Honda mower wheel adjustment. Best Self-Propelled Lawn Mower Reviews 2023

Best Self-Propelled Lawn Mower Reviews 2023

Deciding on the best self-propelled lawn mower isn’t as easy as it used to be. Do you need commercial or residential quality? Do you want to use gas or batteries for power? How much grass do you need to cut? Are you a mulcher or a bagger?

Having tested dozens of the best walk-behind lawn mowers from entry-level residential to the top professional models, we got our Pro team together to choose our top mowers in a range of scenarios.

One of the big things changing in the market is Honda’s announcement that the brand is exiting the lawn mower market. While you can still buy Honda mowers until they run out of stock, 2023 marks the end of production. We still highly recommend them, but due to the news and iffy availability, we’re not considering Honda as part of our choices this year.

Best Self-Propelled Gas Lawn Mower

Commercial: Exmark Commercial X-Series Self-Propelled Lawn Mower

As we bid adieu to Honda this year, the HRC series still gets two thumbs up from us while you can get them. From there, we turn to Exnark and its Commercial X line that complements its Lazer Z zero-turn mowers well. Some professionals will certainly turn to the higher-capacity 30-inch model, but we expect the 21-inch model will find its way onto more trailers.

Exmark wisely uses a Honda 163cc GXV engine with a legendary reputation for reliability. It’s fed by a generous 1-gallon fuel tank and turns the blade at tip speeds up to 18,500 fpm. There’s also an option for a Kawasaki FJ180V engine if you’d like to step up to a 179cc engine.

The deck is 1/4-inch aluminum construction that keeps the weight down (112 pounds) while maintaining high durability. The deck is adjustable from 4.5 inches on the high side all the way down to 1 inch while the drive runs at speeds up to 4.2 MPH.

Residential: Toro Super Recycler Series 21-Inch Self-Propelled Lawn Mower

Toro runs deep in the residential lawn mower sector and our favorite among them is the Super Recycler series. Getting the best of all the technology Toro has to offer, our top recommendation (model 21565) includes the Personal Pace drive system and the Smart Stow design that allows you to vertically store the mower even though it’s a gas model.

It uses a 163cc Briggs Stratton engine that produces 7.25 ft-lbs of torque and just under 17,000 fpm blade tip speed.

Toro touts a commercial-grade construction on this model and includes a lighter aluminum deck rather than steel. In addition to that, you get outstanding cut quality, especially on the mulching side (you better with the name Super Recycler!). Wrapping it up, the Personal Pace drive system adjusts to your walking pace so there are no levers or dials to adjust.

Best Self-Propelled Electric Lawn Mower

Just a few years ago, if you wanted to find the best battery-powered lawn mower, you could only find residential models. Now, there’s an emerging class of professional-grade options and we have picks for both Pros and homeowners.

Professional: Milwaukee M18 Fuel 21-Inch Self-Propelled Lawn Mower

There aren’t many true commercial self-propelled lawn mowers with lithium-ion power sources. Milwaukee launched their effort in 2022 with a monstrous 10 ft-lbs of torque that tops what you typically see from a 200cc gas engine. It’s more than just muscle, though. Its blade and deck combine to handle mulching and bagging better than most.

As you roll into fall, the mower’s high-lift mode keeps the blades at 3300 RPM to help pull those lightweight leaves and clean up your lawn. Other features include 180° LED lighting, LED battery indicators facing you, variable speed thumb bar (in addition to the speed wheel), a durable build, and much more.

Price: 1099.00 with two 12.0Ah batteries and dual-port Rapid charger

Residential: EGO Select Cut XP 21-Inch Lawn Mower with Speed IQ

The evolution of EGO’s flagship mower is interesting. It started with the dual-battery Peak Power model that raised the bar of what lithium-ion is capable of. Then, we saw the first stacked-blade SelectCut options that improved cut quality and effectiveness in tall grass. The two technologies combined in the SelectCut XP. Now EGO adds Speed IQ to the mix.

Speed IQ is a self-propelled drive system that automatically adjusts to your pace. However, it’s not a spring-loaded set of handles like Toro uses on its Personal Pace models. Instead, there’s a sensor doing some serious engineering magic… and it works like a charm from our brief time with it at Equip Expo 2022 (formerly GIE).

Price: 599.00 bare, 999.00 with a 12.0Ah battery and Turbo charger

Best Large Walk-Behind Lawn Mower

Commercial: Greenworks Commercial 30-Inch Self-Propelled Lawn Mower

Can a battery-powered commercial mower really displace gas models? Greenworks Commercial has an 82V 30-inch model that got our attention at the Equip Expo in late 2022, and it’s hard to ignore as a legitimate option. It has the power to replace a 200cc gas engine with blade speeds up to 16,000 FPM. On a full charge, it can cover up to 2 acres.

There are drive system features worth considering as well. Independent hub wheel motors engage what Greenworks calls the Easy Turn System (ETS), making the mower easier to maneuver. Another big deal is that there is a powered reverse function—something that’s incredibly helpful with the weight of mowers in this class. The controls are all up next to your hands and there’s even a display to help you keep track of your battery levels.

Price: 1999.99 bare, 2999.99 with three 8Ah batteries and a dual-port charger

Residential: Toro TimeMaster 30-inch Personal Pace Mower

With 10 ft-lbs of torque delivered from its Briggs Stratton 223cc engine, the 30-inch Toro TimeMaster is our pick as the best large walk-behind lawn mower. Not only does it deliver big power to turn its time-saving 30-inch blade, but it also features Toro’s Personal Pace self-propelled drive and Spin-Stop that lets you stop the blade without shutting off the mower.

It all adds up to big-time savings on larger lawns. Grab model 21200 if you want an electric start or the 21199 if you don’t mind a recoil start and want to save 100.

Price: 1599.00 (21199), 1499.99 (20200)

Best Self-Propelled Lawn Mower for the Money

Toro’s 21-inch Recycler (21352) offers an excellent value for budget-minded homeowners. It’s a Made in the USA rear-wheel drive system powered by a Briggs Stratton 140cc engine. It comes ready to mulch, bag, or side discharge and you don’t have to worry about changing the oil. Just check the levels and add more when it’s necessary.

Best Self-Propelled Lawn Mower Brand

No one in the self-propelled lawn mower market dominates like Honda. Their engines enjoy a reputation for quality and durability every other manufacturer is shooting for, and their mowers are simply outstanding.

They typically run at a premium, though. Both Honda mowers and Honda-powered mowers are more expensive than similar designs from other brands. The big kick in the pants is Honda leaving the market, though.

That opens the door for Toro. There are a lot of Toro models we recommend for good reason and hit a wide range from budget-friendly homeowner mowers to commercial zero turns. It’s one of the best-selling brands of walk-behind mowers.

Getting hard sales figures is tough to come by, and it’s always possible we missed the mark. However, we see more Honda and Toro walk-behind mowers on commercial trailers and residential lawns than any other brand.

Best Self-Propelled Lawn Mower for Bagging

You don’t have to ditch your current self-propelled lawn mower and buy a whole new one to improve your bagging efficiency. In most cases, adding a high-lift blade to your current mower will make a significant difference. With the exception of electric mowers, you don’t need to worry too much about matching the brand making the blade, but you do need to match the arbor style and the length. The package should tell you which brands it is compatible with.

If you’re still in the market for a new mower, higher RPMs make for better airflow and bagging. Check mowers with a 160cc or higher engine and compare the top blade speeds. You can always swap blades, but you can’t change the speed.

Pro Tip: If you have a 2-point or 4-point deck height adjustment, set the front wheels of your mower one notch higher than the rear to improve bagging.

Best Self-Propelled Mulching Lawn Mower

Similar to a high-lift blade for bagging, you can improve your mulching efficiency with a mulching-specific blade. These usually have additional cutting edges that cut the clippings more times before they drop back into the grass. Keeping the blade sharp ensures you get the best mulching results every time you mow.

If you’re in the market for a new mower, look for a 160cc or higher engine to give you the torque you need to keep your blade speed high in thicker grass. Remember, you can always add a mulching blade, but you can’t make up for an underpowered engine.

Pro Tip: You get the best mulching results if you’re only taking an inch or two off the top of your grass, so make sure you stay on top of lawn maintenance during the peak cutting season.

Best Self-Propelled Lawn Mower – Priorities

Best Rear-Wheel Drive Self-Propelled Lawn Mower for Hills: YBravo Gen II 25-inch Commercial Mower

After running into issues with other commercial walk-behind mowers, we turned to YBravo 25-inch commercial mower to take care of a 3-acre soggy field that our ZTs only bogged down in. Its Kawasaki 180cc engine kept the blade turning where others simply stalled.

When it’s time to move out of the radio station swamp and you’re going for a more professional look, its cut quality is excellent as well. Available in a 21-inch and the 25-inch model we tested, Ybravo is worth serious consideration.

If you have a Bad Boy dealer closer to you, check out the same model sold under the Bad Boy brand name.

Price: 1299.00 (25-inch model)

Best All-Wheel Drive Self-Propelled Lawn Mower: Toro 22-inch Personal Pace All-Wheel Drive Mower 21472

AWD mowers are what you turn to for work on slopes and uneven terrain where it’s possible to have a wheel or two lose traction. For the best all-wheel drive self-propelled lawn mower, we like the Toro 21472 Personal Pace model.

Its 22-inch deck is on the larger size of standard mowers and the Personal Pace system is easy to work with once you get used to it. If you switch between mulching and bagging, the mower’s lever system is super simple.

Packing plenty of power with its 163cc Briggs Stratton engine, it’s not so much that it destroys the competition. It’s that its performance is excellent and the innovations are genuinely helpful while keeping its price in check.

Self-Propelled Lawn Mower Recommendations

Not every mower earns an award, but there are several other models we recommend that didn’t find a place earlier in the article. Check these options out if one of the others doesn’t fit your needs.

Best Lawn Mower Buying Guide – What We Look For

Gas vs Battery

Gas power still wins the day when you’re highest priorities are keeping your purchase price down and your power level high. With advancements in battery and motor technology, the OPE world is shifting towards battery power, though. It’s cleaner and quieter to run and requires less maintenance.

However, you have to look at premium models to get true gas power, and runtime can be a limiting factor. It’s also less likely you have a service center nearby that can get you back up and running quickly if there’s a problem.

If your lawn is a 1/4-acre or less, there are a lot of battery-powered options available. Once you get beyond that size, you need to consider how many batteries you’ll need and legitimate options really start to thin out once you hit 1/2 an acre. With larger lawns, newer battery-powered zero turn mowers are a legitimate option.

Take a deeper look at the comparison between gas and battery power in this article.

Commercial vs Residential

This might be better titled “professional vs homeowner” considering there are both commercial and residential professional crews. Regardless, commercial mowers are built with better components and commercial engines, creating a machine that is built to last for years of high-hour daily use.

If you’re a homeowner mowing once a week or so, a good residential mower can still last for 5 or 10 years (or more) if you take care of it. It just uses components and engine designs better fit for occasional use.

Engine Size and Cutting Power

If you stay on top of your mowing and cut quality isn’t a high priority, an engine as small as 140cc is likely fine.

Move up to the 160cc–180cc class for better performance when the grass is thicker and taller, or when you want to make sure you get excellent mulching, bagging, and/or clean cuts. The greater power improves lift and is less likely to bog down in thick patches.

When you’re looking at deck sizes beyond 22 inches, you should start looking for engines in the 180cc–200cc range (or higher) to ensure it can keep the RPMs high while it’s cutting such a large swath.

Cut Quality

We look for three major components of cut quality: evenness, mulching size, and bagging efficiency.

Evenness is pretty straightforward. When we’re testing, we look for grass blades that weren’t cut and indications that there wasn’t enough lift to clip all of the blades at the same level.

When mulching, smaller clippings are better since they drop down closer to the base of the remaining grass. We also look to see if a mower is prone to leaving trails and clumps.

For bagging, it’s all about how much grass is collected, if the chute tends to clog while we’re cutting, and how much grass is deposited back to the ground.

Noise Level

One of the major benefits of battery-powered mowers is the lower noise levels compared to gas, but that doesn’t mean gas mowers have to be obnoxious. We expect higher levels than battery-powered models and that is typically the case.

When we test noise levels, we measure from our operator’s ear to get an idea of what the person using the mower should expect. Even though some mowers are quieter than others, we still recommend hearing protection when you’re using a gas model.

Fuel Efficiency

How efficient gas mowers use fuel has a very direct effect on your wallet, especially when you’re mowing every day as a Pro.

Fuel efficiency testing is more than just a runtime calculation. The cutting swath of a mower comes into play, especially on those 25 and 30-inch models. With larger lawns, it’s possible to get more cutting done per gallon of gas with an engine that uses more gas per hour.

Deck Size

21 or 22 inches is pretty standard for most mowers. Jumping up to a 25-inch or 30-inch mower may seem tempting, but it’s not for everyone.

If your lawn is a 1/4-acre or less, the time you gain with a larger deck might not mean a whole lot of time savings. Where you really gain some time is on lawns that are a 1/2-acre or more.

Keep in mind, larger deck-size mowers are heavier. When you have to mow wet or soggy areas, the weight can work against you.

Steel vs Plastic (Poly) Deck

The vast majority of gas mowers have steel decks while battery-powered models have a much higher percentage of plastic poly decks.

Those poly plastic decks are tougher than they look, but they probably won’t hold up as well as steel in the long run. It’s still highly unlikely that you’ll wear through one before it’s time to replace the mower, though.

However, there’s a whole lot more design flexibility that comes with poly decks, and engineers can do some amazing things to help with airflow that directly affects cut quality along with bagging and mulching efficiency.

Deck Height

Here in Florida, we have a lot of St. Augustine grass that we cut at 3 1/2 inches, so we prefer a mower that has at least a 4-inch maximum deck height.

Depending on what species of grass you have, you might be able to get away with a lower height, but 4 inches is a good all-around benchmark.

On the low end, most of us aren’t cutting golf course greens (you’d use a reel mower for that, anyway), so the minimum deck height usually isn’t an issue.

However, if you use a blade that dethatches or scalps for maintenance or re-seeding, you might want to make sure the deck height gets low enough—typically 1 1/2 inches or less.

Height Adjustment

Single-point height adjustments are the easiest since you can raise or lower the deck with just one lever. It’s common on battery-powered lawn mowers, but not so much on their heavier gas counterparts.

Part of that is because the single-point mechanisms tend to introduce additional flex into the system and the weight of a gas mower puts more strain on the mechanism. So while we generally prefer single-point, we understand why gas mowers may opt away from them.

Pro Tip: Set the front wheels one notch higher than the rear wheels to improve bagging efficiency on 4-point or 2-point adjustable mowers.

Adjustment Levels

If you’re really OCD, more height adjustments mean more precise cutting. Realistically, most of us are going to find a good height on any mower as long as it hits the maximum and minimum heights we mow at.

Setting the Speed

The type of speed adjustment your self-propelled lawn mower has can make or break your experience. There are pull levers, thumb push levers, full push bars (Toro’s Personal Pace), and iterations on those.

Try it at the dealer before you buy it. If you hate working the mechanism for a couple of minutes, imagine what it’s going to feel like after 30 minutes or an hour.

Front-Wheel Drive, Rear-Wheel Drive, or All-Wheel Drive?

Front-wheel drive lawn mowers are typically the least expensive and work well for even terrain. They also help you turn the easiest since you lift up the drive wheels as you make your turns.

Rear-wheel drive mowers add some cost but create better traction on hills and slopes. They’re particularly good at pushing the mower’s weight uphill where front-wheel drives start to lose traction as they try to pull the weight.

All-wheel drive mowers are the most expensive and generally do the best job on hills, slopes, and uneven terrain. On particularly bumpy areas where it’s likely one or more wheels will lose traction, it’s the best bet.

Wheel Size

Larger wheels tend to handle bumps and uneven terrain better than smaller wheels according to manufacturers. However, it’s a claim that Consumer Reports says isn’t really the case.

Electric Start

If you’ve used a gas engine, there’s a good chance you’ve worn out your arm pulling the cord to start it. There’s no doubt that having an electric start on your mower can take away a lot of the frustration.

It won’t make up for poor maintenance, though. A well-maintained mower starts easily on the first or second pull. That begs the question as to whether the electric start is worth an extra hundred dollars.

It’s totally up to you, but if it’s in the budget, we want it.

Mulch, Bag, or Side/Rear Discharge?

Most quality mowers are 3-in-1, meaning you can bag, mulch, or side/rear discharge. Less expensive models often only provide options for bagging and mulching. Which one you choose depends on what type of grass you have, how fast it grows, and your personal preference.

In central Florida where St. Augustine, Zoysia, and Bahia dominate our landscapes, the summer heat and rains make our grass grow incredibly fast. Most of us mulch out of necessity since we almost need a dumpster for the volume of clippings we create.

Handle Positions

Most lawn mowers have 3 handle positions you can set. For tall guys like me or average-height guys like Clint, it helps you find a more comfortable grip. Some mowers opt for 2, or sometimes just 1 handle position.

Value

Value is more than just price. We take a broad look at the performance and features compared to the price to determine the value of each mower.

Honda Lawn Mower Carburetor Adjustment: How to Do It

This post may contain affiliate links. As an affiliate of retailers(like Amazon), we earn from qualifying purchases.

When your Honda lawn mower’s engine doesn’t idle, lacks power at high speed, or won’t start, it could be time to adjust the carburetor. If you have never done this before, you are probably wondering how difficult it will be, what tools you will need, and if you should just call an expert.

Adjustments to a Honda lawn mower’s carburetor should be made after it has been cleaned. If the carb is dirty, adjustments will be temporary. You will need some screwdrivers, a wrench, a carb cleaner, and an hour or two. Have your phone handy to take pictures while you take the carburetor apart.

Keep reading to find out how a carburetor works, what could be causing different problems, as well as preventative measures.

How Does a Carburetor Work?

Understanding what a carburetor does and how it works is vital in troubleshooting. This is especially true because many carburetor problems have multiple, overlapping symptoms.

The carburetor’s role is to provide the space where gas and air mix. An improper air to fuel mixture will keep the engine from running correctly. An incorrect gas and air mix cause most carburetor problems. Your job is to figure out what is causing the mix to be off.

• Float Chamber: The float chamber holds fuel, and as the amount of fluid increases, the float rises until it is pushed into its seat. When fuel leaves the chamber, the float falls. As more fuel enters, it rises again.
• Intake: Air rushes through the throat of a carburetor, and then a narrower passageway called a venturi. This causes the air to speed up, creating a vacuum that pulls fuel into the fuel nozzle.
• Fuel Jet: Once the proper gas/air mixture has been created, the fuel is pulled through the fuel jet. This creates the explosion that powers the engine.
• Throttle Valve: This valve controls the amount of gas that goes into the carburetor. An open valve increases the engine’s power, and a closed valve stops the engine.

Carburetor problems can occur at each of those points, and the way to fix most carburetor problems is to get inside and see which of these is causing the problem.

Why You Should Clean the Mower’s Carburetor

Although you might be tempted to play around with the throttle or make other adjustments, clean the carburetor. Otherwise, any corrections you make will be temporary, and you could wind up causing even more damage to the carb.

Also, get a parts cleaner, such as WD-40 Specialist Carb/Throttle Cleaner. It contains the solvents you need to clean out the gunk, and the spray will blast away dirt and deposits. For tools, you will need screwdrivers and a socket wrench.

Mower Engine Starting Problems

If your engine is not starting, you have difficulty starting it, or it stops after you get it started, then the following could be causing starting problems:

• The main jet, main nozzle, or main nozzle air path could be clogged.
• The float isn’t moving correctly.
• The throttle stop position is wrong.

Mower Speed Problems

If the engine speed does not increase, the speed is unstable, or the engine performs poorly at high speed, then an additional clog to check for is the pilot jet—either its air path or the jet itself are clogged.

Should speed problems happen at low speeds or the idle speed is unstable, then in all likelihood, the pilot jet or its air path is clogged. You will need to check for dirt and clean.

Mower Gasoline Problems

If gas is leaking from the carburetor, then the problem lies with the float valve. Either the float valve is worn out or coated with dirt, or the valve seal is worn or dirty.

Getting to the Mower’s Carburetor

Before you get started, we recommend you disconnect the spark plug cap. This is to prevent the mower from accidentally starting. Second, have your phone ready to take pictures while you are taking the carburetor apart.

Fix Without Taking the Carburetor Apart

You might get lucky and avoid having to take the carburetor apart. To do so, FOCUS on cleaning out the carburetor idle jet. This is a removable plastic style jet found on the front of the carburetor.

• First, spray the carb cleaner and remove the dirt and gunk.
• Look for a plastic screw with a Phillips head bolt. That’s the idle adjustment screw. Loosen and remove it.
• Now you will have access to a rubber plug with a hole. This is the idle/pilot jet.
• To remove the pilot jet, you need to pull it out gently. Use flathead screwdrivers to wedge it up.
• After you get it out, you should clean it with the carb cleaner. The small hole on the end often gets plugged. Honda makes Jet Cleaner sets, but a tiny pin will be a good substitute.
• After you have cleaned the pilot jet, push it back in carefully, and then replace the idle screw. Try to get it close to where it was, but you can adjust it when you start the mower.

Clean Out the Float Bowl

The float bowl is at the bottom of the carburetor. It is easy to take off, but before you do, turn off the fuel line. Then loosen the bolt on the bottom and take out the bowl.

There are two gaskets—one where the bowl connects to the housing, and another one on the bolt. Inspect both for cracks. Then clean out the bowl and replace the housing.

Taking the Mower’s Carburetor Apart

If the mower is still not running correctly, then the carburetor must be taken apart so that you can clean it. This is a much more complicated procedure and could take an hour or more.

• First, remove the air filter. If it is dirty, replace it. A dirty air filter can affect how well your mower runs better. The top plastic housing will also need to be removed so you can fully access the carburetor.
• Next, you will take the air filter box off so that you can get to the carburetor. In most models, it is held on by two bolts. As you loosen the bolts, hold onto the carburetor. The bolts run through the carburetor and mount it to the motor housing.
• Now that you have access to the carb, get ready to start taking pictures. Anything you unhook needs to be hooked back correctly. Keep an eye out for the tiny spring attached to the top.
• Once you have taken the carburetor off, it is time to disassemble. As you do so, check the gaskets—worn ones need to be replaced. Continue taking the carb apart and cleaning. Every hole needs to be clear of dirt.

Finally, the carburetor will have to be reassembled. Hopefully, you took lots of pictures so that you have them as guides.

Rather than taking a carb apart, some folks simply buy a new carburetor. Be sure to check compatibility with your Honda Mower.

Check out this 12-minute video that will take you through the steps of fixing a lawn mower carburetor:

To prevent future problems, make sure you are following Honda’s recommendations. Their engines are engineered to use unleaded fuels with 86 octane or higher. Ethanol fuels can be used as long as the fuel has no more than 10% ethanol (E10). A fuel with methanol should contain no more than 5% methanol.

Copyright article owner is ReadyToDIY.com for this article. This post was first published on 2020-08-27.

Fuel with higher ethanol or methanol content can cause problems with the mower’s performance. The engine’s warranty does not cover damage to the engine caused by fuel with more than 10% ethanol.

If possible, regular unleaded gasoline is ideal. Avoid E85 at all costs because Honda considers it an alternative fuel since it is 85% ethanol and only 15% gasoline.

Storage Suggestions to Prevent Carburetor Problems

These are some suggestions to prevent future carburetor problems. Gasoline can begin to deteriorate within three to four weeks, so use these if you only mow every couple of weeks:

• Fill up the tank. As fuel is exposed to heat or air, it oxidizes and can gum up the carburetor’s jets. Keep the tank full to minimize how much gas can enter the tank through the vent.
• Run the engine out of gas. No fuel = no oxidation. If the mower only has a little gas in the tank, run it dry and close the fuel valve.
• Storage container. Make sure you close the container tightly and store it in a cool place. Honda discourages metal fuel containers since they might rust, and tiny rust particles can clog the carburetor.
• Fuel Stabilizer. Fuel stabilizers should be added if gas is stored either in the container or the mower for three months or longer. If you plan to use the mower within a year, there is no need to drain the gas from the fuel tank or carburetor—as long as you add the stabilizer.

Final Thoughts

Carburetors are an essential and often overlooked part of a lawn mower. If your mower is not running well and you have checked the air filter and spark plug, you might have to work on the carburetor. Taking the carburetor apart and cleaning it is time-consuming but not difficult. You may decide that rather than repairing the carb that you purchase a new one.

Should Lawn Mower Wheels Be the Same Height?

• Why the height of the wheels and deck affects the experience
• Problems associated with sloping mowers
• Height specifications for lawnmowers

What Height Should Mower Wheels Be?

The height of a lawnmower should be between 2.5 to 3.5 inches (6.4 to 8.9 cm), but don’t let it get any longer or shorter than that. Tall and short grass are both bad for your lawn. Fortunately, it’s very easy to change the height of the mower in a few seconds.

Below, you’ll find out why the height of your mower’s wheels and deck matter.

• The height affects the size of the grass. Organo-Lawn points out that the height of your deck and wheels directly impacts the health of your grass. When it’s too low, you’ll have all sorts of issues. If it’s too high, you’ll have a disorganized lawn. Adjust the wheels and deck, knowing how they’ll affect the grass.

• Dense grass needs to be cut evenly. If you’re dealing with dense grass, then it has to have sharp blades to cut it down to size. Many companies tilt their mowers or lower the height because it makes it easier for the mower to cut dense grass. Furthermore, it prevents an uneven, choppy appearance.

• If it’s too low, the grass will reveal dirt and weeds. Low-cut grass is a staple of most neighborhoods, but it shouldn’t be lower than two inches, or dirt will show itself. Also, low-cut grass tends to provide more oxygen and hydration for local weeds to grow. You’ll notice dirt and weeds more than the appealing lawn that you’re working for.

• Tall grass invites bugs and weeds. If you don’t adjust the wheels and deck low enough, bugs will call it home, and weeds will grow. Keep in mind that most weeds need to be removed by their roots to stop them from coming back. Nevertheless, bugs will climb up the tall blades of grass and feel concealed.

• The deck and the wheels can be at different heights. When the deck of the mower is slanted, it’s inevitable that the wheels will be a bit higher or lower. Never confused the two heights since they have very different effects. Low wheels and a high deck will be easy to push, but it won’t cut much grass at all.

As you can see, the height of the wheels and deck can drastically change the performance of the lawnmower. Make sure you know how to adjust both of them before you start mowing your lawn.

Why Are Some Mowers Slanted Forward?

You might’ve worked with tilted mowers that look different from traditional lawnmowers. In fact, all mowers used to have an even deck. If you’re curious about why your mower is tilted, or you want to know more about the benefits, then keep reading.

Here’s a list of five reasons that some lawn mowers are tilted:

• It limits air from getting into the blade assembly. Gravely mentions that their mowers are slanted to prevent air from getting into the mower, which could otherwise slow the movement. It could also prevent the blades from pushing debris efficiently, leading to clogs and a plethora of other problems.
• Slanted decks prevent too much debris from flying around. When the deck is level, grass will fly whichever direction the blades throw it. However, the slanted deck is angled to throw the debris to the back of the mower directly into the bag. It’s an incredibly efficient process that most mowers don’t have.
• You’ll be able to go downhill fairly quickly. SInce the deck is tilted, it helps you move forward and downhill without an issue. You won’t be limited, nor will you feel the push-pull resistance that’s present when you’re pushing a level mower. If you have a hilly yard, then a slanted deck is a good option.
• It’s more aerodynamic, allowing you to move the mower easier. The tilted deck cuts through the air and grass in front of you, much like the shape of an airplane moving through the sky. Rather than being flat and air-resistant, a tilted mower slices through the air and pushes easily.
• There might be a misalignment on the lawn mower. Although tilted mowers usually have a designed purpose, they could be misaligned due to a mechanical error. Tilted mowers could be caused by loose wheels, rusted bearings, and broken mower decks. All of these issues cause a wiggling, loose deck that tilts forward.

Now that you know why some lawn mowers are tilted, you might feel like you want to get one. Most of them are excellent mowers, but it’s a good idea to know what you’re getting yourself into before you buy a new one.

To discover two major cons that come with sloped mowers, read on.

Downsides of Sloped Mower Decks

Sloped mowers have their pros and cons, both of which deserve to be recognized. There are only two issues that you might have to deal with if you choose to go with a sloped mower.

It’s Harder to Move Uphill

While it’s easier to push the mower downhill, the front of the deck can scrape the grass, making it harder for you to push it uphill. Even if you’re using a riding mower, the front bumper will undoubtedly scratch steep hills. Do your best to lift the mower and tilt it back as you’re moving it uphill unless you’re mowing.

If It Tilts Too Far, It Could Damage the Blades

All mowers with tilted decks come ready to go, but as they grow old, the deck can misalign and move forward. Another possibility is if you lower the deck too much and raise the wheels at the same time. Either occurrence will cause the blades to slice into the deck. It’ll ruin the blades, smoke the engine, and cut into the deck. In other words, you’ll have to buy a brand-new mower.

Both of these problems aren’t always present, and they’re easily avoidable. As long as you’re a responsible owner, then you’ll be able to use a sloped mower. The wheels don’t have to be the same height as the deck, but they need to be aligned with one another.

Conclusion

The wheels on a lawnmower are all the same height. The illusion that they’re not is often caused by the deck sloping forward. Make sure your mower is level and aligned before you start mowing the grass.

Here’s a quick rundown of the post:

• Your mower’s wheels should all be at the same height: 2.5 to 3.5 inches (6.4 to 8.9 cm).
• A slanted deck will make it look like the wheels aren’t the same height.
• Slanted mowers have trouble moving uphill, but they’re more aerodynamic than their level counterparts.

The Best Self-Propelled Lawn Mowers in 2023 for Making Your Yard Work Easier

These lawn mowers drive themselves, taking the load off you in the process.

By Roy Berendsohn Published: Mar 21, 2023

One of the perks of the warm-weather season is getting to spend time outside. If you own your own home and have a yard, it’s very likely that in order to enjoy your outdoor space, you need to mow the lawn. The larger the yard, the more work it will be to maintain. If you have a lot of grass to cut, you’d be wise to consider a self-propelled lawn mower especially now that there are a ton of sales just in time for Memorial Day.

The primary difference between a standard push mower and a self-propelled mower is that the former moves when you push it, and the latter essentially moves itself with only your guidance. Once the engine is running, all you have to do is squeeze a handle or push a lever and the mower will start moving forward with you as you walk.

Turning the mower around is your job, but once you have your heading, just keep the drive handle squeezed and escort the mower down the path, no pushing necessary.

Self-propelled law mowers take power off the engine and route it via a belt to a pulley on the transmission and axle. When you move the drive control lever on the mower handle, you tension the belt, causing the pulley to turn, and this drives the transmission, moving the mower forward.

Move the drive control lever back and the tension is released, the pulley stops turning, and the mower stops moving forward. The belt-driven transmission is a time-tested design to power the mower and take the load off you in the process.

What to Consider

A mower is like many consumer products in that the more features a manufacturer adds, the more expensive it becomes. But a longer or more eye-catching list of features isn’t necessarily better. Sometimes less is more. Here are the most important to keep in mind.

Front-wheel drive mowers tend to be less expensive than rear-wheel drive units. They can be easier to turn because you don’t have to disengage the drive wheels to do so. Simply push down on the handlebar to raise the front wheels off the ground. However, their traction isn’t as strong on hills or when the bag is full, as there isn’t as much weight over the drive wheels.

Rear-wheel drive mowers do cost more and aren’t as easy to turn, as you do need to disengage the drive—but this isn’t too much of a hassle. Rear-wheel drive mowers shine on hills and inclines, and when the grass bag is full. In either scenario, weight is shifted rearward and over the drive wheels, which enables superior traction, thus making the self-propel more effective.

An engine as small as 125 cc can power a mower, but most are somewhere in the 140 cc to 190 cc range. A large engine helps when powering through tall, lush grass or in extreme conditions, such as with a side discharge chute in place and mowing tall weeds in a border area. Also, the extra torque provided by a larger engine can improve bagging when the going gets tough (tall, leaf-covered grass in the fall). But if you mow sensibly and pay attention to deck height—and especially if you don’t let your lawn get out of control—an engine between 140 and 160 cc has more than enough power to get the job done.

A mower can have all four wheels the same diameter (7 to 8 inches), or it may have rear wheels that range from 9.5 inches to 12 inches in diameter. Larger rear wheels help the mower roll more easily over bumpy ground.

With some mowers you can start the engine with the twist of a key or the press of a button. It’s a great option, but a luxury. Keep the mower engine tuned and use fresh fuel with stabilizer added to it, and you’ll never have trouble starting.

Any number of mechanisms can control a mower’s ground speed—a squeeze handle, a drive bar that you press forward, even a dial. There’s no single right answer here. Look at the design and think about how you like to work. For example, if more than one person will be using the mower (and not all of them are right-handed), a drive control like that on a Toro Personal Pace mower might be the answer. Just push down on the bar to make it go faster. Let up on the bar to slow down.

A mower that can bag, mulch, and side discharge is known as a three-function mower, the most versatile kind. Two-function mowers bag and mulch or mulch and side discharge.

Mowers will typically have one, two, or four levers to control the deck height. Single-lever adjustment is the easiest to use, but it requires more linkage, which adds weight and complexity. If, for some reason, you find yourself varying deck height frequently, it’s a good option. Otherwise, two or four levers work just fine.

Only Honda makes a gas-engine mower with a high-impact plastic deck (there are battery mowers that have plastic decks). Otherwise, mowers generally have a steel deck, and a few manufacturers—Toro, for one—offer a corrosion-resistant aluminum deck. An aluminum deck won’t rot the way a steel deck will, but you still need to keep it clean.

This is a hose fitting mounted on top of the mower’s deck. When you’re done mowing, hook up a hose and run the mower to power wash the underside of the deck. We’ve had mixed results with these, but they’re better than just letting a mass of dried grass clippings accumulate.

expensive mowers come with a more durable bag with more dust-blocking capability. If you bag a lot, especially leaves or other lawn debris in the fall, then you need a mower with a higher quality dust-blocking bag. Having said that, if you rarely bag, the standard one that comes with a mower will last you the life of the mower.

Also called wide-area mowers, machines in this subgroup help homeowners better reconcile their need for more power and speed with the fact that they may not have enough storage for a tractor or zero-turn mower. A typical residential walk mower has a single-blade deck that cuts a swath from 20 to 22 inches wide. Wide-cut mowers (built for homeowner use) have either a single blade or, more typically, a pair of blades, cutting from 26 to 30 inches with each pass. Some of these are rated for light commercial use and have larger decks, in the 32-inch range, and engines that start at 223 cc and go up to about 337 cc.

Wide-cut mowers typically employ gear or hydrostatic drive transmissions, and they have top speeds of about 4 to 6 miles per hour. At their fastest, they move so quickly you have to trot to keep up with them. Needless to say, they’re overkill for small yards; only opt for one of these if you’ve got a significant plot of land that you need to keep tidy, but not one so large that you’d be better off going with a full-on riding mower.

How We Tested and Selected

We compiled this list based on Popular Mechanics mower testing and our knowledge of the lawn mower market at large. For our testing, we put mowers through the paces using our standard Popular Mechanics methodology: We cut turf grasses such as fescues and blue grass and rougher non-turf grasses like Timothy, clover, orchard grass, and wild oats, all in both normal and shin-deep heights. We mow uphill, downhill, and across the faces of hills. The maximum slope we cut is about 30 degrees.

That may not sound like much, but it’s about all you can do to stand on it, let alone push a mower up it or across it. We mow damp and wet grass to test general cutting performance and whether clippings accumulate on the tires. And we cut dry and dusty surfaces to see how well the bag filters under less-than-optimal conditions.

Honda HRN 216VKA

Key Specs

Honda mowers enjoy a sterling reputation. Having tested their walk and self-propelled mowers for the last 30 years, we feel confident that Honda‘s entry level mower is a great choice for homeowners looking for power and durability. The HRN features a GCV 170 gas engine that’s built to withstand long hours of operation.

If you do your own maintenance (and most owners who buy this class of product do), you’ll appreciate the easily accessible spark plug and the fuel shutoff valve that enables better winter storage. Close the fuel shutoff and run the mower until it sputters to a halt. This will clear the carburetor of any gasoline, which will prevent the ethanol in it from disintegrating and causing running issues later on. Open the shutoff valve in the spring, add some fresh gasoline, and the mower should start easily.

All this maintenance stuff is great, but we can also tell you that our past test findings on other Hondas prove that their cut quality is outstanding for cleanliness. Sharp blades deliver a velvet-like finish. And their bagging ability is also quite good, in the same league with other well-bagging mowers from Toro.

In all, if you take mowing seriously, you should enjoy this Honda. If you have a little wiggle room in your budget, consider the Honda HRX, which features a mower powerful engine and a composite deck that won’t rust and is renowned for its durability.

One note is that Honda has announced that it will cease selling lawn mowers in the United States after this year—so if you’re considering buying one, best do it sooner rather than later.

Toro Recycler 60-Volt Max Lithium-Ion

Key Specs

Toro mowers have garnered more recommendations from us than any other brand for two reasons: build quality and cut quality. These were amply demonstrated in our testing as the Recycler turned in the best ratio of cut area per amp-hour of battery in the self-propelled category, while at the same time not skimping on cutting, mulching, or bagging quality.

We attribute this outstanding mower performance to three features, all upgrades to the previous version of this machine. First, the air vent at the front of the mower deck seems to improve mulching and bagging performance. Toro calls it Vortex technology, a design that increases air flow under the deck. This helps to stand the grass for a cleaner cut, which improves mulching performance, and also allows better airflow into the bag when collecting the clippings.

Next, the company’s redesigned “Atomic” blade configuration appears to assist the air flow and clipping movement. Finally, the three-phase, 60-volt motor is exceptionally efficient, resulting in a large cut area for a single battery.

Toro has maintained features that make this mower work: rear wheel drive, a one-piece deck that’s all steel (no plastic nose), 11-inch wheels to help it roll over roots and crevices, and the same fold-forward handle that was an industry breakthrough when it was introduced some years ago.

Ryobi 40-Volt Brushless Self-Propelled Mower

Key Specs

This is one of Ryobi’s top-of-the-line mowers, and it’s American-made construction is something we wish we saw more of. It delivers a tremendous cut area with its two 6-Ah batteries providing a total of 12-Ah of capacity, and its X-shaped blade leaves a pristine surface in its wake.

Ryobi estimates the design should provide 70 minutes of run time; we didn’t time our cut, but it strikes as plausible. Its rear-wheel drive and reasonably aggressive tire tread pattern provide good hill climbing and sidehill cutting performance, and its bagging on all surfaces (level, sidehill, and uphill) is also commendable.

Other ease-of-use features include an easily installed or removed bag that mounts and dismounts straight up and down through the handle; deck adjustment is quick and easy thanks to a single-level deck height adjustment. The straight edge deck is polypropylene; it will never rust and needs very little care other than basic cleaning.

Toro TimeMaster 30 in. Briggs Stratton Personal Pace

The Toro Timemaster 30-in. mower has been around for several years and has earned a reputation as a sturdy workhorse for homeowners who want to cut down on their mowing time. It’s also used by some professionals as well. A few years ago the Timemaster got a slightly more powerful Briggs and Stratton gas engine, so it should have no issues powering through most demanding mowing jobs.

The Timemaster is rear-wheel drive and features Toro’s Personal Pace drive system that’s used on many of its self-propelled mowers. This allows the mower to move at your speed by simply pushing down or releasing the handle, which is spring-tensioned.

With a 30-in. deck, Toro claims the Timemaster will help you reduce your mowing time by about 40% compared to using a standard-sized mower. You can mulch, back, or side discharge with the Timemaster, and the handlebar can be locked in a fully vertical position to reduce space consumption in storage.

If you have half an acre to a full acre of lawn to mow and prefer the experience of a walk-behind mower versus a tractor or zero-turn, the Timemaster is worth a look.

Craftsman M220

Key Specs

Craftsman mowers have been doing very well in our tests, so we can recommend this one because it’s so much like the many other of the brand’s models that we’ve tested. If you’re looking for a good blend of maneuverability and power, you’ll get it with this mower. Its front drive helps move it along and makes it easy to turn.

It’s important to note that front-drive mowers do lose some traction when running uphill, particularly with a full grass bag. But if your slope is less than 20 degrees, and you’re not bagging uphill, you’ll be fine. The side discharge will also help you handle tall grass. Adjust the two deck levers to bring the mower up to full height and have at the rough stuff.

The fact that this mower bags, mulches, and side discharges is a plus, enabling you to handle a wide range of mowing conditions, from early spring and late into the fall. Three-function mowers like this are our preference for that versatility.

Toro Super Recycler Self-Propelled Lawn Mower

Key Specs

This is a beauty of a mower, with a cast-aluminum deck and a smooth-running Briggs Stratton 163-cc engine. We tested the Honda engine-equipped version, and it was effective at both bagging and mulching, even in moist grass.

Equipped with rear-wheel drive and the Personal Pace system (the farther you push the drive bar, the faster the mower goes), it’s an effective hill climber and moderately effective on sidehill cutting. It has relatively small 7.5-inch tires on all four corners, which causes this Toro to bump up and down a bit on washboard surfaces. But the good news is that it’s equipped with a far higher quality tire than we’re used to seeing these days. We didn’t notice them pick up any grass on moist surfaces.

Other features we like include its forward-fold handle that has a built-in shock absorber that Toro calls a Flex Handle Suspension, and a high-quality grass bag that loads through the handle, from the top.

QA

Are there special maintenance considerations with self-propelled mowers?

Yes. Both front- and rear-wheel drive mowers typically feature a drive belt, which can crack or wear out over time. Fortunately these belts are not difficult or particularly expensive to replace.

Secondly, you may have to replace the drive wheels occasionally. These wheels are driven with gears. there are typically teeth on the inside diameter of the drive wheel that line up with a gear on the axle. These teeth can wear out, especially if they are made of plastic. Higher-end mowers may feature drive wheels with a metal gear that meets the metal axle gear, which improves longevity of these components.

My lawnmower says I don’t ever have to change the oil, but just add oil when needed. Is this OK?

It’s not a good idea to never change the oil in your lawn mower. In a lawn mower, same as a car, oil degrades over time and is less effective at reducing heat and friction in metal components. Changing the oil in your lawn mower is easy to do and will significantly increase its service life. For most homeowners, changing the oil at the beginning or end of each mowing season should be sufficient, though there is certainly no harm in doing it more often.
