Lawnmower decks are not often thought about, but they are important. Having a level deck on your lawnmower may or may not be important to fix. Does it matter if it’s level? A lawnmower deck should be level so that it can cut grass evenly. The deck of a lawnmower is the covering that protects the engine and person. It hides the blades and the debris that comes out of the lawnmower including the grass cuttings. Keeping the mower level keeps your grass uniform as you cut. Having a level lawn mower is important, but how can to do it? Read on below for more information about how to level your lawnmower deck.

Why Should You Level Your Lawn Mower Deck?

Leveling your lawnmower deck allows you to cut the grass evenly. If you notice that your grass looks uneven and choppy, then that is because you need to adjust or fix your lawnmower deck. The issue may be with the blade itself, but the deck can also be a cause for uneven grass. Plus, it is fairly easy to fix. Keeping your lawnmower deck level also keeps your lawnmower in good shape. You can maintain it and make sure that your lawnmower is running well and cutting grass efficiently. Also, if your lawnmower deck is uneven, then it is potentially hazardous. To keep yourself and others safe when using a lawnmower, make sure the deck is level so that the grass blades do not come out and the blades stay covered. If the blade is not covered properly, then you should not be using the lawnmower. The blades are sharp and dangerous, and you can harm yourself or others easily. Always make sure that your lawnmower deck is attached securely and level so that you can avoid ruining your equipment and you can avoid getting hurt. (Source) If you see that the grass is cut uneven, you can also sharpen the blade if you find it dull and not cutting grass very well. Just be sure to always exercise caution when dealing with the blade of a lawnmower because it is sharp and can potentially harm you. If your lawnmower has grass clippings cleaned off of it and the deck is level, then there should be no issue with its performance and it should cut the grass well.

How to Level Your Lawn Mower Deck

Leveling a lawnmower deck is not a complicated procedure. To start off, check the owner’s manual or look up the owner’s manual online for specific information for your lawnmower. Then, just follow along with those instructions. If you are looking for a general idea or a list of steps, then read below for how to level your lawnmower deck. Firstly, wear the correct clothing. Be sure to protect yourself so that you do not injure your hands or any part of you with the mower blade. The main item to wear is thick gloves. Wearing them will help protect your hands from getting injured when handling a lawnmower. You should also consider wearing long sleeves, jeans, and closed-toe shoes so that you are covered and at least partially protected when working with the lawnmower. Basically, you are adjusting the tightness of the screws to adjust the height of the deck and evening that out. The nuts against the deck are what you will loosen and adjust. These are connected to the deck and can control how high or low the deck sits. You will want to loosen the side of the deck that is lower, and tighten the side that is higher. Adjust these sides and measure the deck from the ground up on each side to see if the deck is even. Adjust until they are even and your deck will be successfully leveled.

How to Clean/Mantain Your Lawn Mower

Cleaning and maintaining your lawnmower is important. You do not want the blade to become dull and you want your engine and your wheels to run smoothly. Getting your blade, deck, and wheels clean is important to keep your lawnmower in great shape. Keeping up on this will make your lawnmower last for years, and you can avoid causing any damage to it. To make sure you keep up on the maintenance and cleaning of your lawnmower, you should check it out before using it. If you use your lawnmower daily for mowing the lawns of others, then clean out the lawnmower daily or weekly and check under the deck to see if it requires cleaning. If you mow every week to every 2 weeks then you should clean it out about every month. If you want to clean it after every use then you may do that as well, but cleaning after every handful of uses will still be enough to keep your lawnmower in great shape.

To properly clean a lawnmower deck you should take the deck off so that you can fully access the underside. This is the part that will be the most dirty from lawn clippings. Remove the grass and wipe it out with a cloth or paper towels. Then, you can clean out the deck with water and scrubbing if necessary. Before putting the lawnmower deck back on, make sure it is fully dry. You can gently clean off any other part of the lawnmower. Exercise caution when cleaning off the blade. You can remove this part or clean it separately from the mower. You can also sharpen the blade if you desire but look into your owner’s manual for specific details on how to sharpen the blade. Using a cloth or paper towels, you can wide down the wheels and any part that has grass clipping built up on it. Carefully wipe the engine and remove any dirt and grass. Then, you can fill up your lawnmower with gas if it needs a refill and put together all of the parts that you may have removed for cleaning. Finish putting the deck, blade, and other parts together and put your mower away. Now it’s ready for its next use!

Lawn Mower Leaving Uncut Grass – The complete fix with pics

It’s a common source of frustration, and ARGH!! But more than likely, the solution is a simple one, and you can fix it right now.

So why is my lawnmower leaving uncut grass? The most common cause of uncut grass is a dull blade, but it’s not the only possible reason:

This problem has many possible causes, but a dull blade is a usual suspect. Check your engine performance; if you feel the engine doesn’t sound right or it’s sluggish, go ahead and solve engine-related issues first.

Very often, uncut grass is simply caused by a dull blade. If you need help inspecting and safely sharpening your blade, check out “How to sharpen mower blade video”.

Check For Blade Damage

A defective blade will cause all kinds of problems in the grass-cutting and collection department. Examine your blade checking for loose bolts, and damaged, misaligned, bent, or broken blade tips.

Mower blades have it tough, and hitting stones, sprinklers, stumps, and dog toys is all part of the job. Mower blades turn about 50 times a second – that’s 200 mph at the tip.

So when you hit something, it’s going to damage even hardened steel. Bending and gouging chunks from the metal blade will cause uneven cutting and a horrible vibration.

A blade may look OK, but they do wear. If it’s more than four seasons old, it’s probably worn out. The leading edge cuts the grass and is easy to see when it’s worn. The trailing edge stuffs the bag, and as that edge wears, it becomes much less efficient. The solution – replace the blade.

Never attempt to repair or bend a blade; the metal has been specially treated, and interfering with this can cause them to shatter.

When replacing the blade, go ahead and get a new bolt and washer. They’re mower-specific and also specially treated, so a bolt from the local hardware store won’t be up to the job.

A torque wrench should be used to tighten the bolt to the correct specification. A quick check of your mower manual or on the dealer site will give the spec.

Blade Orientation

It’s possible to fit a blade backways, so if you fit a blade recently, just check that the orientation is correct. Hey, it could happen a Bishop, don’t worry about it!

Imagine looking down at the blade from above – the leading edge of the blade will turn clockwise.

Bent – A bent blade is dangerous, and it will cause lawn scalping and vibration and, if ignored, will damage the mower engine.

Replace – A new blade will solve many problems; when changing the blade, replace the bolt and washer too.

If you need video help replacing the blade, check out the “Replacing blade video” and if you need mower blades, check out the Amazon link below.

Dull Blade

Is your blade sharp? A dull blade is the number one reason for leaving uncut grass. The blunt blade will damage your lawn in no time at all; it tears the grass and leaves a jagged edge which turns the grass tips yellow.

The recommended way to repair the yellow grass damage – regularly cut with a sharp lawnmower blade. I tell my customers to sharpen at least once per season, and more depending on how often you cut and terrain type. A sharp blade is the secret to a healthy, beautiful green lawn.

Check out “Blade maintenance tools” here; they make the sharpening process a ton easier. And if you need video help sharpening the blade on or off the mower, check out the “Blade sharpening video”.

Sharpen – Your blade needs a sharpening once per season, at least. If you file your blade regularly, it won’t take much effort to keep sharp.

What Blade Type?

You may have a blade that doesn’t suit your climate or your needs. So what’s in a blade? Quite a lot of clever engineering, actually. A blade looks pretty unimpressive, but change it out for a different type or a new one, and you’ll be surprised at the difference in cut and finish.

There are two main blade types, the lift blade, and the mulching blade; each has its own strengths. How you intend to handle your clippings and your climate will likely dictate which blade suits you.

lawn, mower, mowing, uneven

Lift Blade

The Lift blade, also known as the 2 in 1 (collecting or discharging), vacuums the grass upright, before cutting and moving it to the bag. These lift blades are designed for collecting grass and come in low, medium, and high lift.

Lift means sucking power, and a higher lift blade will require a more powerful engine. The lift is created by curving upwards of the trailing edge of the blade; the steeper curve, the more powerful the lift. These blades love to bag grass, wet or dry.

Lift blade – Also known as a 2-in-1, it loves to bag grass, wet or dry.

Mulching Blade

A true Mulching blade is designed to finely chop and disperse grass clippings, not collect them, a proper mulching mower won’t have a grass bag.

Many of the latest mowers are fitted with a hybrid mulching blade, also known as a 3-in-1 (collecting, discharging, or mulching). It’s sort of half lift blade, half mulching blade – Jack of all trades if you like.

These blades are not designed specifically to collect and are really best suited to very regular dry weather cutting; if the grass is tall, a 3 in 1 mulching blade may struggle to bag efficiently.

Mulching – 3 in 1 blade is good but has limited success in more challenging conditions.

Check Engine Power

Check if the throttle is set correctly; it should be set to fast/run when cutting. Does your throttle cable need adjustment? Is the engine running as it should? If the engine power is reduced, the mower will not cut well, especially when it hits a patch of heavy grass.

Lawnmowers are generally very reliable; give them a tune-up and blade sharpening at the start of every season, regardless of how it’s running. The oil should be changed every 50 hours, and clean the air filter every 25 hours, and more often in dusty dry conditions.

Check throttle lever – If your engine seems to be a bit sluggish, first check that the throttle is set to full. The lever may be reading full throttle, but the cable may not be moving at the carburetor end.

Second, check the air filter is clean, try running the engine without the filter, and see if it makes any difference.

Gas – Old fuel is the number one cause of poor engine performance. Fuel older than a month goes stale and will gum up the inside of the carburetor.

This blocks the fuel feed ports and causes fuel starvation. This results in a sluggish engine and a poorly cut lawn.

Try using a fuel stabilizer, it will keep the gas fresh for up to two years, but more importantly, it will prevent gumming up of the carburetor. Check out the video showing how to mix and add gas stabilizer. The page includes a link to the gas stabilizer I use.

If you suspect bad gas is causing sluggish engine output, try draining the fuel tank, and carburetor bowl, and filling them with fresh gas. This will very often fix the issue, and if it doesn’t, a full carburetor cleanout will.

Clutch Slip

If you’re using a tractor mower, you may have a clutch system fitted. The clutch or PTO (power take-off) transfers the engine power to the blades. When the clutch starts to fail, it slips, which means the blades are not turning with the same power or speed as normal. It will be especially noticeable in taller, heavier grass.

Some walk behind lawn mowers (Honda) use a very similar clutch set up, so if you have a separate control to engage the blade, then it’s likely you have some form of the clutch system, but note these clutch systems are cable operated and the tension on the cable may simply need to be adjusted.

If you don’t have a clutch fitted, but you do have a separate lever to control the blades, then your blades are possibly controlled by a tensioned belt. The Toro Time-master is a good example. (see below)

Pulling the bail lever tightens the tension on the belt and makes the blades spin; the tension on the belt may simply need to be adjusted.

Clutch – Three types of clutch, the tractor PTO, the Honda blade clutch, and finally, the belt-type clutch fitted to the Toro Time-master.

My Overall Top #1 Pick: PowerSmart Lawn Mower, 21-inch 170CC, Gas Powered Self-Propelled Lawn Mower

Normally I look for more eco-friendly options for my top pick lawn mower, but in this case I thought that the extra power and runtime of a gas-powered lawn mower was worth it.

That’s because uneven ground can be more challenging to get over, which means it usually takes longer to mow an uneven lawn. The extra power is also great for handling grass that may be in different growth stages and different heights.

If you want to learn to take better care of your lawn, I’ve got you covered. My article How To Mow Your Lawn Like A Professional talks about how you can be more in tune with your lawn, regardless of where you live or what kind of grass you have.

If a little of your grass has started to grow stems instead of leaves, this lawn mower will power right through them. No problem, and minimal blade dulling thanks to the more powerful engine.

This larger design is actually great for uneven ground since the larger cutting deck helps create a smoothly cut lawn.

This lawn mower is also self-propelled, which can be a huge advantage on uneven ground. The motor will help you get the wheels out of dips in the ground and stuck areas without a problem. The self-propelled wheels are also great for controlling your lawn mower safely on hills and curves in the land.

Overall, this PowerSmart Lawn Mower is a great option if you’re looking for a versatile lawn mower that will make your lawn look great.

I always recommend choosing higher-quality lawn mowers because the extra investment really pays off in the long run. However, if your lawn is uneven and difficult to mow it’s even more important to get a higher quality lawn mower.

If your ground is a little more than uneven, I’ve also got a list of the best lawn mowers for hills.

Not only will high-quality lawn mowers get the job done better and faster than cheaper models, they also keep you safer at the same time.

High-quality lawn mowers also tend to last longer and need less maintenance. You’ll still want to take your lawn mower in for an annual tune-up, but you’ll need other maintenance less often. Plus, high-quality lawn mowers tend to come with more durable blades and other longer-lasting components.

Don’t want to work with an uneven lawn? This video will teach you how to level your lawn quickly for easier care and keeping. Or rather, this video will show you what not to do, with some tips on how to get it right!

Power Source

There are three basic power sources for lawn mowers—corded electric, battery-powered, and gas powered. I have all three power sources included on this list since corded options can be a good choice on smaller uneven lawns.

Think about how eco-friendly you want your lawn mower to be. Electric options—both battery-powered and corded, are the best solution if you want an eco-friendly lawn mower.

However, gas power has some advantages too. While battery-powered lawn mowers are almost as powerful as gas versions, gas powered mowers still have the edge when it comes to run time. A tank of gas in your lawn mower will generally go farther than a battery.

If you’re worried about power sources and how long you can mow your lawn with each option, you should also think about how often you should mow your lawn. That will help give you a better idea of the time commitment to mow your lawn.

Wheels and Traction

Unlike other lawn types, it’s important to look for a lawn mower with even-sized wheels when you’re going to be mowing on uneven ground. That’s because you never know which wheel might get caught in little dips or need to go over a bump. Uneven wheels can make it harder to keep your lawn mower moving on uneven ground.

You also need to make sure the wheels have good traction since the uneven ground can make it easier for your lawn mower to slip and slide instead of moving where you need it to.

My Reviews of the Lawn Mowers for Uneven Ground

This gas-powered lawn mower is larger than most push-behind options. Its 21-inch mowing deck is big enough to tackle any lawn small enough to walk and mow.

If you want a riding lawn mower this might be a good next best option though thanks to its larger size.

The cutting deck is made from durable stainless steel that will last for years. Its simple design is meant to resist damage while helping protect the motor above the deck.

Durable high-traction wheels also help make this lawn mower a good option for uneven ground.

The wheels will help your grip and maneuver over every bump and roll in the ground. The wheels are the same size, which is good for maneuverability on unpredictable ground.

The large grass collection bag in the back can sometimes be a little tricky to maneuver with, but it’s usually only an issue on ground with a lot of sharp bumps. gentle uneven ground will work fine with this design.

If your lawn is a little too rough for this design you can simply switch the mower to side-discharge to make it easier to maneuver.

The 5 different height settings also work to give you all the height versatility you need.

Powerful motor for faster more even cutting Incredibly durable for long lasting use 5 different height settings gives you more control over your lawn’s appearance Easy start design makes this lawn mower accessible for almost all users 3 different grass discharge settings to give you more control – Not very eco friendly
  • Brushless effecient motor
  • 40V battery
  • Easy start design
  • Mulching bag included
  • 20 inch cutting deck
  • Part of the Greenworks 40V line

If you’re looking for a similarly powerful model, but want an eco-friendly version, you’re going to have to pay a little more.

Fortunately, Greenworks has a battery-powered lawn mower that’s almost as big as the PowerSmart lawn mower.

While this design has the same 21-inch cutting deck its actual width is a little closer to 20 inches. That makes it just the tiniest bit smaller than the PowerSmart lawn mower.

The powerful battery on this design also lets you mow for longer without taking a break.

It’s a highly efficient option that also protects you from harmful gasoline fumes and is more environmentally friendly to boot.

The one thing I don’t like about this design is that it’s a lawn mower only, and you don’t get the battery you need with this kit. That’s great if you already have a 40v Greenworks battery from an old lawn mower, but it’s less convenient if you need to buy one now.

That said, the money you’ll save off gasoline costs will pay for the more expensive battery over the life of this lawn mower. And since it’s a more powerful long-lasting battery you probably won’t need more than one to be able to mow your whole lawn.

Long-lasting battery suitable for a wide range of lawn sizes Powerful cutting blade helps keep your grass heathy and looking it’s best. Durable design so you can use this lawn mower longer Large cutting deck makes mowing your lawn much faster Mulching option included, no need for a separate mulching tool – Doesn’t come with its battery, you need to purchase the battery separate.
  • 16 inch cutting deck
  • 32 lbs.
  • 6 height settings
  • Corded electric
  • Easy start

If you’re looking for something a little more affordable, the Lawn Master 16 inch lawn mower is a good option.

It’s got a smaller cutting deck for sure, but that can actually be a good thing for smaller yards. It’s easier to maneuver smaller lawn mowers around tighter spaces and small corners in your lawn.

lawn, mower, mowing, uneven

This lawn mower is also lighter than larger options, which means it’s a good choice if you don’t have a lot of upper arm and core strength.

However, this model is a corded electric lawn mower.

It’s got plenty of power, but the corded design also means that you’re limited to the length of your extension cord while you’re mowing, another reason this lawn mower is best for small lawns.

Remember that you need to keep and eye on your extension cord while you’re mowing. You don’t want to accidentally mow over the cord and cut it while you’re working.

Durable design for longer use affordable than most alternatives Smaller profile for tight corners and navigating bumps and uneven ground Adjustable height design, gives you more control over the appearance of your lawn Reliable corded electric, never worry about a dead battery or running out of gas – Not designed for large lawns, corded design limits the range of this lawn mower.
  • steel cutting deck
  • 21 inch cutting deck
  • 3 in 1 design
  • Gas powered
  • 18.8 lbs.
  • 6 cutting height options

This gas-powered lawn mower comes with a lot of advantages. One of my favorite things about this lawn mower, since it comes from Craftsman, is that it’s incredibly durable and well designed.

But in addition to that, features like an auto-choke and a recoil system make it really easy to use.

The 21-inch deck is plenty of space to maneuver your lawn mower, while also being well suited to uneven ground.

High grip wheels and several bagging or discharge options make this lawn mower even more versatile.

Overall, if you’re looking for a long-lasting and durable gas-powered lawn mower, this model from Craftsman is a good choice.

Easy start makes this lawn mower simple to use Durable steel design saves money and keeps this lawn mower working longer Grippy wheels for better maneuverability and control Lightweight and comfortable to push for even the largest lawns – Some people receive lawn mowers with minor damage in shipping, always check your lawn mower before operating.

Greenworks G-MAX 40V 16” Cordless Lawn Mower Best Eco Friendly

  • 16 inch cutting deck
  • Battery powered
  • 40V design
  • Easy start
  • 37.5 lbs

This last lawn mower is a good option if you’re looking for a slightly smaller battered powered lawn mower, but still want the power and versatility of my high-end pick.

This is basically the same lawn mower, but with the a smaller cutting deck and a lighter profile.

That’s a good thing if you have a smaller lawn. It’s also a great option if you don’t have a ton of space for your lawn care tools.

Like the larger version of this lawn mower, it offers high traction wheels for better maneuverability.

This design also comes with variable cutting heights to help you find the perfect option for your lawn. Even though this 16-inch design is a little smaller, it’s still big enough to help even out the appearance of your uneven lawn.

This lawn mower is also a little heavier compared with the competition. However, it’s design helps make it easy to push and maneuver, so you won’t notice the extra weight. This smaller design is otherwise very similar to my hig-end pick, but it’s better suited to smaller lawns than the high-end design.

Plus, with GreenWorks FOCUS on sustainability and eco-friendliness, this is one of the most eco-friendly lawn mowers you can get.

Easy to store, takes up less space in your garage or shed Battery powered, very eco-friendly design and manufacturing Maneuverable wheel and deck design Long handle for better leverage and control, also improves user comfort – Takes a little longer to mow large lawns compared with mowers with bigger cutting decks

My Top Pick: PowerSmart Lawn Mower, 21-inch 170CC, Gas Powered Self-Propelled Lawn Mower

Overall, of all the options on this list, the PowerSmart lawn mower offers the best combination of features for uneven ground. Its powerful gas motor helps keep you mowing longer, allowing you cover more ground before you stop. 5 different height settings work to make sure your grass is exactly the right length.

If you’re looking for a good deal on a powerful and effective motor, this is it.

Final Thoughts On The Lawn Mowers for Uneven Ground

Mowing on uneven ground can be a little bit more difficult than mowing the lawn that’s already perfectly flat. But that doesn’t mean that your uneven lawn has to look any worse than your neighbor’s. You can still get great-looking healthy grass with the right tools and a little extra time and effort.

Plus, a lot of the things you do to keep your grass looking great will actually help even out the lawn over time.

So, you could have a great-looking lawn today, and be working toward having a lawn that is easier to take care of tomorrow. Just don’t give up when it takes a little more time to get your lawn looking the way you want it to. And happy mowing!

Why is My Bad Boy Mower Cutting Uneven?

The Bad Boy mower is a powerful and reliable lawn cutting machine, but like any piece of equipment, it can experience problems.

One common issue that many Bad Boy mower users have experienced is uneven cutting. This can manifest in a variety of ways, such as leaving rooster tails of uncut grass, creating ragged edges along the cut, or leaving bare patches in the lawn.

Uneven cutting can be caused by a variety of factors, including low tire pressure, dull or damaged blades, uneven or worn out wheel height adjustment, improperly adjusted cutting deck, and clogged deck or air filter.

In this blog we will be discussing the causes of uneven cutting, how to diagnose the problem, how to prevent uneven cutting and important maintenance tips for Bad Boy mower.

Causes of Uneven Cutting

Low tire pressure

Refers to the possibility of the mower’s tires not being properly inflated. When the tire pressure is too low, it can lead to an uneven cutting pattern. This happens because the tires may not be able to provide adequate support and stability to the mower, causing it to tilt or lean to one side during operation.

When the mower is not level, the cutting deck becomes uneven, resulting in an inconsistent cut across the grass. The blades may not make proper contact with the ground, leading to patches of grass being cut too short or left untouched.

To address this issue, you should regularly check and maintain the tire pressure according to the manufacturer’s recommendations. Inflate the tires to the recommended PSI (pounds per square inch) using a reliable tire pressure gauge and an air compressor if necessary. Keeping the tires properly inflated will ensure that the mower remains level and provides a more even cutting performance.

Dull and Damaged Blades

dull or damaged blades, can contribute to an uneven cutting pattern on your Bad Boy mower. Dull blades or blades with damage, such as nicks or bends, can result in an inconsistent and jagged cut across the grass.

lawn, mower, mowing, uneven

When the blades are dull, they struggle to cleanly slice through the grass blades. Instead, they tear or shred the grass, leading to an uneven appearance. Similarly, blades with nicks or bends can cause the mower to vibrate or wobble during operation, further affecting the quality of the cut.

To address this issue, regularly inspect the blades for signs of dullness, nicks, or damage. If you notice any issues, it’s recommended to sharpen or replace the blades as needed. Sharpening the blades ensures a clean and precise cut, while replacing severely damaged blades may be necessary for optimal cutting performance. It’s important to follow the manufacturer’s instructions or seek professional assistance when sharpening or replacing mower blades to ensure safety and proper alignment.

Uneven or Worn Out Wheel Adjustment

an uneven or worn-out wheel height adjustment, can contribute to an uneven cutting pattern on your Bad Boy mower. The wheel height adjustment mechanism allows you to set the cutting deck at a specific height to achieve an even cut.

If the wheel height adjustment mechanism is uneven or worn out, it can result in one side of the cutting deck being higher or lower than the other. This imbalance causes the mower to cut the grass at different heights across the mowing path, resulting in an uneven appearance.

To address this issue, inspect the wheel height adjustment mechanism for any signs of damage or wear. Ensure that all the wheels are properly aligned and adjusted to the same height. If the mechanism is damaged or worn, it may require repair or replacement by a qualified technician to restore proper wheel height adjustment functionality. Regularly checking and maintaining the wheel height adjustment mechanism will help ensure a consistent and level cutting performance.

Improperly Adjusted Cutting Deck

an improperly adjusted cutting deck, can contribute to an uneven cutting pattern on your Bad Boy mower. The cutting deck on the mower should be properly adjusted to ensure that it is level and parallel to the ground during operation.

If the cutting deck is not adjusted correctly, it can tilt or angle in a way that results in an uneven cut. This misalignment can cause one side of the deck to be higher or lower than the other, leading to an inconsistent cutting height across the mowing path.

To address this issue, you should check and adjust the cutting deck to ensure it is level and parallel to the ground. Refer to the mower’s manual or consult a professional for specific instructions on how to adjust the cutting deck for your particular model. Properly aligning the cutting deck will help achieve a more even and uniform cut across the grass. Regular maintenance and adjustment of the cutting deck will contribute to a consistent and desirable cutting performance.

Clogged Deck or Air Filter

clogged deck or air filter, can contribute to an uneven cutting pattern on your Bad Boy mower. A clogged deck or air filter can impact the mower’s performance and airflow, leading to an inconsistent cut.
