There are a number of reasons, mechanical and otherwise, why a mower won’t run. The good news is that fixing most all of the issues is easy enough for a DIYer to handle.

Lawn care can be tedious, but once the grass starts growing in the spring, mowing becomes a fact of life in most neighborhoods. When you finally muster the strength to tackle that first cut of the season, there are few sounds as disheartening as that of a lawn mower engine that turns over but doesn’t start.

Before you drag the mower in for repairs or invest in costly replacement parts, first make sure that a clogged air filter, soiled spark plug, damaged safety cable, clogged mowing deck, or contaminated gas isn’t to blame. Work through the following steps, and you may be able to get your puttering grass guzzler up and running again in no time.

A lawn mower repair professional can help. Get free, no-commitment repair estimates from pros near you.

Change the lawn mower carburetor filter.

Your lawn mower’s air filter guards the carburetor and engine from debris like grass clippings and dirt. When the air filter becomes clogged or too dirty, it can prevent the engine from starting. To keep this from happening, replace paper filters—or clean or replace foam filters—after every 25 hours of engine use.

The process for removing the filter depends on whether you are operating a riding or walk-behind lawn mower. For a riding mower, turn off the engine and engage the parking brake; for a walk-behind mower, pull the spark plug wire from the plug. Then, lift the filter from its housing.

The only choice for paper filters is replacement. If you’re cleaning a foam filter, wash it in a solution of hot water and detergent to loosen grime. Allow it to dry completely, and then wipe fresh motor oil over the filter, replace it in its housing, and power up the mower—this time to the pleasant whirring of an engine in tip-top condition.

Check the spark plug.

Is your lawn mower still being stubborn? The culprit may be the spark plug, which is responsible for creating the spark that ignites the fuel in the engine. If it’s loosened, disconnected, or coated in water or carbon residue, the spark plug may be the cause of your machine’s malfunction.

Locate the spark plug, often found on the front of the mower, and disconnect the spark plug wire, revealing the plug beneath. Use a socket wrench to unscrew the spark plug and remove it.

Check the electrode and insulator. If you see buildup, spray brake cleaner onto the plug, and let it soak for several minutes before wiping it with a clean cloth. Reinstall the spark plug, first by hand, and then with a socket wrench for a final tightening. If the problem persists, consider changing the spark plug.

Clear the mower deck of debris.

The mower’s deck prevents grass clippings from showering into the air like confetti, but it also creates a place for them to collect. Grass clippings can clog the mower deck, especially while mowing a wet lawn, preventing the blade from turning.

If the starter rope seems stuck or is difficult to pull, then it’s probably due to a clogged deck. With the mower safely turned off, tip it over onto its side and examine the underbelly. If there are large clumps of cut grass caught between the blade and deck, use a trowel to scrape these clippings free. When the deck is clean again, set the mower back on its feet and start it up.

Clear the vent in the lawn mower fuel cap.

The mower started just fine, you’ve made the first few passes, then all of a sudden the mower quits. You pull the cord a few times, but the engine just sputters and dies. What’s happening? It could have something to do with the fuel cap. Most mowers have a vented fuel cap. This vent is intended to release pressure, allowing fuel to flow from the tank to the carburetor. Without the vent, the gas fumes inside the tank begin to build up, creating a vacuum that eventually becomes so strong that it stops the flow of fuel.

To find out if this is the problem, remove the gas cap to break the vacuum, then reattach it. The mower should start right up. But if the lawn mower won’t stay running and cuts off again after 10 minutes or so, you’ll need to get a new gas cap.

Clean and refill the lawn mower fuel tank.

An obvious—and often overlooked—reason your mower may not be starting is that the tank is empty or contains gas that is either old or contaminated with excess moisture and dirt. If your gas is more than a month old, use an oil siphon pump to drain it from the tank.

(It’s important to be careful as spilled oil can cause smoking, but there are other reasons this might happen. Read more about what to do when your lawn mower is smoking.)

Add fuel stabilizer to the tank.

Fill the tank with fresh fuel and a fuel stabilizer to extend the life of the gas and prevent future buildup. A clogged fuel filter is another possible reason for a lawn mower not to start. When the filter is clogged, the engine can’t access the gas that makes the system go. If your mower has a fuel filter (not all do), check to make sure it’s functioning properly.

First, remove the fuel line at the carburetor. Gas should flow out. If it doesn’t, confirm that the fuel shutoff valve isn’t accidentally closed. Then remove the fuel line that’s ahead of the fuel filter inlet. If gas runs out freely, there’s a problem with the fuel filter. Consult your owner’s manual for instructions on replacing the filter and reassembling the mower.

Inspect the safety release mechanism cable.

Your lawn mower’s reluctance to start may have nothing to do with the engine at all but rather with one of the mower’s safety features: the dead man’s control. This colorfully named safety bar must be held in place by the operator for the engine to start or run. When the bar is released, the engine stops. While this mechanism cuts down on the likelihood of horrific lawn mower accidents, it also can be the reason the mower won’t start.

The safety bar of a dead man’s control is attached to a metal cable that connects to the engine’s ignition coil, which is responsible for sending current to the spark plug. If your lawn mower’s engine won’t start, check to see if that cable is damaged or broken. If it is, you’ll need to replace it before the mower will start.

Fortunately, replacing a broken control cable is an easy job. You may, however, have to wait a few days to get the part. Jot down the serial number of your lawn mower, then head to the manufacturer’s website to order a new cable.

Check to see if the flywheel brake is fully engaged.

The flywheel helps to make the engine work smoothly through inertia. When it isn’t working properly, it will prevent the mower’s engine from working.

If it is fully engaged, it can make a mower’s pull cord hard to pull. Check the brake pad to see if it makes full contact with the flywheel and that there isn’t anything jamming the blade so the control lever can move freely.

If the flywheel brake’s key sheared, the mower may have run over something that got tangled in the blade. It is possible to replace a flywheel key, but it does require taking apart the mower.

Look out for signs that the mower needs professional repairs.

While repairing lawn mowers can be a DIY job, there are times when it can be best to ask a professional to help repair a lawn mower. If you’ve done all of the proper mower maintenance that is recommended by the manufacturer, and gone through all of the possible ways to fix the mower from the steps above, then it may be best to call a pro. Here are a few signs that indicate when a pro’s help is a good idea.

  • You see black smoke. The engine will benefit from a technician’s evaluation, as it could be cracked or something else might be worn out.
  • Excessive oil or gas usage. If you’ve changed the spark plugs, and done all of the other maintenance tasks, and the mower is consuming more than its usual amount of oil or gas, consult a professional for an evaluation.
  • The lawn mower is making a knocking sound. When a lawn mower starts making a knocking sound, something could be bent or out of alignment. It may be tough to figure this out on your own, so a pro could help.
  • A vibrating or shaking lawn mower can be a sign of a problem beyond a DIY fix. Usually something is loose or not aligning properly.

A Beginner’s Guide to Riding Lawn Mower Maintenance: Tips and Tricks for a Long-Lasting Machine

If you want a reliable mower all season, who doesn’t? Then your Riding mower will need a tune-up at least once a year, preferably in the spring before the season starts. If you want a reliable mower all season, then your Riding mower will need a tune-up at least once a year, preferably in the spring before the season starts.

So what is riding mower maintenance? To maintain a riding mower, the following components need attention:

At the very minimum, the oil should be changed at the start of the season. If your mower is new, change the oil after the first 5 hours of use. Some mowers will have a useful tune-up interval chart stuck under the hood or under the seat.

Topping Up Oil

Checking and topping up the oil is good practice, but it’s not a substitute for an oil change. If your mower has an oil filter, change it when changing the oil, this is where all the contaminants are trapped.

Info Sticker – Helpful charts are fitted to some mowers showing intervals and part numbers; however, I’ve found the Husqvarna belt labeling to be wrong; just saying!

About Your Gas Engine

All tractor-mower engines are very durable, failures, in my experience, are rare, and when they happen, it’s usually associated with poor or low oil. That’s why checking your oil regularly and oil changes are so important.

When To Tune-up Your Gas Engine?

When should I service? I advise my customers to service their mowers at the start of the season, not at the end. Mowers that overwinter without being prepared usually suffer from gummed carburetor issues. You can avoid gumming by adding a gas stabilizer to the fuel system.

What Is Gas Stabilizer?

Gumming of small engine carburetors is a real problem. Over the winter months, the old gas eats away at the inside of the carburetor. This is so common, and it’s so simple to prevent. Use a gas stabilizer at the season’s end; dump a few drops into a full tank of gas, and run the engine for a short while. See the video here about mixing and adding gas stabilizers.

If your mower is running rough, changing the oil, plugs, air, and fuel filter may not fix it. Gas mowers that run rough usually require carburetor cleaning. Check out “Carburetor troubleshooting.”

What Tools Are Needed?

A tune-up isn’t technical, and no special tools are needed. Like many tasks, it’s about the right knowledge and good preparation.

When it comes to tools, you don’t need top of a line kit but do buy good quality tools because good tools, well cared for, will last a lifetime.

What Tune-up Parts Needed?

All engines have a model code and date stamped somewhere. Briggs Stratton stamp their codes into the metal valve cover at the front of the engine. Kohler has a tag, and Honda has a sticker on the body.

Tune-Up Kits – Tune-up kits will include plug(s); oil; oil filter (if fitted); air filter; fuel filter – everything you need.

If you’re having trouble identifying your engine type, you can usually identify the right tune-up kit by the shape of the air filter.

Check out your engine maker specs:

Inspection Tune-up

In this guide, we will tune up a single-cylinder engine. In addition to a tune-up, doing an overall visual inspection is good practice. Mowers create a lot of vibration, so look for any loose or damaged components, check rear axle oil, belts, pulleys, deck spindles, deck arms, battery connections, cables, etc. Finding problems now is usually cheaper than them finding you later.

Your mower may not be the same as the demo model, but that’s not important; the process will be close to identical no matter what model you have.

Engine Makers

There are many different makes of mowers, and many are fitted with the very reliable Briggs Stratton single-cylinder engine. Kohler, Kawasaki, and Honda are also quite popular engines. All these engines are simple and easy to work on.

Tune-up Stepped Process

We’ll begin the tune-up process by starting and running the engine for a while, just long enough to warm the engine oil. Warm oil flows more freely, which helps remove more contaminants from the engine.


1 Wire – Remove the plug wire and leave it off until you are ready to start the engine later in the process.

2 Plug – Remove the old spark plug. To avoid cross-threading, thread the new plug in by hand before using the plug tool.

Snug the plug down and give it a little tighten…. not too tight! Don’t fit the plug wire just yet.


3 Drain – Drain the oil while the engine is still warm; this helps the draining process.

4 Remove – If you can’t find your oil filter, then you don’t have one, so you can go ahead and skip this part.

Remove the old filter, you may need an oil filter tool, but they’re usually not that tight.

5 Fit Filter – When fitting the new filter, apply some oil to the O-ring; it prevents distorting the seal when fitting. Only tighten the filter – hand tight.

6 Add Oil – If your mower has an oil filter, then check the oil level again after your test run of the engine. This can be done at the end of the tune-up.

7 Check Levels – Add oil a little at a time, and check the level. Overfilling is not good for the engine. It will cause oil leaks, misfiring, and lots of smoke.


8 Check – Check the rear axle oil level. The front Axle has greasing points; for this, you’ll need a grease gun.

Air/Fuel System

9 Air – Remove the air filter and clean the airbox being careful not to allow dirt into the carburetor. Refit the new filter or clean the old filter, by tapping it on a hard surface or better-compressed air, but never wash a paper filter.

10 Remove – Gas filters are found on the gas line between the gas tank and the carburetor. If you have a gas tap fitted, it’s useful to turn it off before removing the old filter.

Gas filters may be directional, and if so will have an arrow that points to the carburetor.

11 Clean – Gas tank grit is common, I use a suction bottle and tube to remove it, and sometimes I have to remove the tank to clean it.

Blade Sharpening

12 Jack – Be sure to use an axle stand or block of wood to secure the mower, as you’ll be working under it.

Don’t take any chances. Check out the tools on the blade maintenance page.

Deck – If you are not comfortable working under your mower, then remove the deck. Most decks will be pretty simple to remove.

Balance – Removing deck blades for sharpening and balancing is the best practice. Inspect the blades for damage, and replace them if bent, cracked, or worn. If the blades are in good condition, you can sharpen them in place.

13 Sharpen – Sharpening your blade is done with a good quality flat metal file.

Flat – Begin by dressing the face of the blade to remove any small nicks.

Bevel – Now we will file at the same angle as the bevel; some blades will have the bevel facing the other way.

Dress – Now dress on the opposite side to remove the burrs. A sharp blade is the secret to a beautiful, healthy lawn, and it extends the life of your mower.

Belt Check

14 Check – Check the condition of the belts. Most mowers have at least two belts, one for driving the mower and one for driving the blades. Some mowers will have more.

Flat Spot – These belts have a difficult job and can be the cause of various issues. Regular inspection will tell you if your belt is at the end of its life.

Blistering – Things to look for are flat-spotting, glazing, cracking, and fraying.

Glazing – Worn or damaged belts cause slip, which in turn will cause vibration. The vibration can, if ignored, go on to cause lots of other issues.

Cracking – Better to take care of this now; waiting for it to break can cause other damage.

husqvarna, lawn, mower, maintenance, your

Deck Leveling

15 Pump – Check tire pressure and set it to 1bar/15psi. Some customers like a lower pressure, and that’s okay; what’s important is that they’re all the same.

16 Level – Decks tend to drop at the front over time. Place the mower on level ground.

Measure the height of the four corners of your cutting deck.

Measure – Let your deck down approx. halfway. Now measure the height of the four corners of your cutting deck.

Note the highest corner, and adjust all other corners up, so they match.

Adjust – You’ll find adjusters at each corner; they’ll have a lock nut that will need to be released first.

Turning these bolts adjusts the deck up and down. Spray with WD40 – makes life a little easier.

Clean Cut – Decks that sag will impact your lawn, causing damage to your blades and your lawn. Keep your deck level and blades sharp; you’ll be rewarded with a healthy lawn and a healthy mower.

Diesel Engine Difference

Some manufacturers offer small diesel engines in their mowers; the main advantages are fuel efficiency and lots of torque. Mostly they’re fitted to the commercial range. Diesel engines tend to be very reliable. However, they cost a lot more than a gas engine to repair when they fail.

Diesel Tune-Up

Service to a diesel engine will include oil; oil filter; fuel filter; air filter. Doing an oil and filter change is just as important on a diesel. Note, if you’re changing a fuel filter on a diesel engine, the air must be purged from the system before starting the engine.

Purging Diesel Fuel System

Fill the new filter with fresh diesel before fitting. Then pump the primer, if installed on the machine. If you don’t have a primer – open the fuel lines at the injectors by about two turns, and now crank over the engine until fuel spills from the fuel lines. Tighten up the lines, and your good to go. If your diesel still doesn’t start after purging, it must be purged again.

Related Questions

Should I run my lawnmower out of gas for winter? Using a gas stabilizer is better than running a mower out of gas. The stabilizer will keep gas fresh and protect the fuel system over the winter months. Running the gas out of the mower doesn’t prevent gumming of the carburetor.

Can you store a lawnmower vertically? A lawnmower should be stored on its wheels; however, if you drain the oil and gas from the engine you can store it in any position you like.

Husqvarna lawn mower maintenance

Whether it’s a petrol mower, a battery-powered mower or a robot lawn mower, keeping them in the best condition possible will ensure they perform their very best for years to come. In this guide, we will look at how to clean and maintain the 3 most commonly owned types of lawn mowers, so that you can enjoy trouble-free mowing!

Signs your mower needs servicing

When your mower is working as it should, it’s all too easy to skip its annual servicing. Postponing by a few weeks won’t be an issue, but annual mower servicing is something you want to remember to do for one good reason. it keeps your mower in the best working condition possible, saving you time and money on spares and repairs down the road.

How often your mower needs servicing can be found in the user manual for your model. However, there are times when your mower may need an early service, especially if you are noticing any of the following:

  • Your lawn mower is having difficulty starting.
  • Your mower is making loud knocking or rattling sounds.
  • There’s smoke coming from the mower.
  • It shudders when mowing thick grass.
  • There’s a high-pitch whining sound when starting.
  • There are more vibrations than usual.
  • The mower is giving an uneven cut.

The easy way to clean a petrol lawn mower

The way you clean your mower will largely depend on the power supply and the type of mower you have. For the most part, electric and petrol push mowers follow the same types of cleaning with a few apparent differences such as petrol, oil, and fuel filters. For simplicity, we’ll look at each of the basic steps to cleaning a lawn mower, going deeper into the different steps when needed.

  • Place your mower on a level and secure surface such as a driveway or patio. If the mower is not on a flat surface, you run the risk of it tipping over as you work on it, which could cause injury.
  • If your mower has a grass catcher, remove it and close the discharge flap to prevent any grass or debris from being pushed back inside during cleaning.
  • To access the underside of your mower’s deck, always tip your mower backwards towards the handles, never to its side. This will prevent oil and any fuel that may still be in the engine from seeping into places it shouldn’t.
  • Inspect the underside of the mower for any dried grass clippings that have built up. It is also a good idea to check the condition of the blades. Even if there is a small amount of debris on the mower deck, then you’ll want to give it a wash while you have easy access to it.
  • Most walk-behind mowers come with a fitting to attach a garden hose to flush the deck. If not, you’ll want to turn your mower on its side and use gloved hands to remove the bulk of any grass, dirt, and debris.
  • If your mower has a Hose fitting, turn the hose on, and then start the mower and let it run, allowing the water supply to clean the underside. After a few minutes, turn off the water and check the underside. Don’t turn on the mower if you have to have it on its side to clean the blades.
  • Repeat the process if there is any debris remaining. It’s often a good idea to complete this cleaning task after each use before the grass clippings have a chance to dry and harden.
  • Should the lawn mower’s blades be a little blunt, then it might be time to replace them. Husqvarna does not recommend sharpening the blades on your mower. Check out Husqvarna’s Lawn Mower Blade Replacement Guide for an in-depth look at how to change the blades.
  • Keep the air filter clean by removing it and giving it a blast with some compressed air (never use liquid to clean your air filter!).
  • Also, check and replace the spark plugs. You’ll likely need to change the spark plugs every year or two, depending on use.

How to quickly clean a battery lawn mower

While many of the mower cleaning techniques will be similar between petrol and battery models, there are a few differences to be aware of. Here’s how to safely clean down your battery-powered lawn mower.

  • Place your lawn mower on a solid and level surface, turning it onto its side to access the cutting deck.
  • Make sure the battery has been removed to prevent any accidental starts.
  • Using a gloved hand or a washing-up brush, run around the underside of the cutting deck to remove the bulk of the dry grass and debris.
  • For hard-to-reach areas, use compressed air to remove any debris. DO NOT use water on a battery mower. especially from a hose or pressure washer.
  • To clean the chassis and cutting deck, take a damp cloth and wipe everything down.
  • Clean the blades with an old toothbrush or hard bristle brush. If the blades are showing signs of damage, it may be time to replace them.
  • Allow everything to dry properly before replacing the battery.
  • To clean the battery, use a dry microfiber cloth to wipe down all surfaces and connection points. the same with the charger.

How to clean Husqvarna Automower®

It is highly recommended to have Automower® professionally serviced and cleaned at your local Husqvarna dealer at the end of every season. In between professional servicing, you can give Automower® a bit of TLC as and when you want.

Taking just 10-minutes of your time, Automower® is easy to keep in tip-top condition. It’s important to note that you should never wash a robot or battery-powered mower with a pressure washer, running water or solvents. While designed to deal with surface water and rain, pressurised cleaning could force water into the electrics. which isn’t something you want to do.

husqvarna, lawn, mower, maintenance, your

Regular annual servicing not only enables Automower® to work its best but also maintains the mower warranty.

  • Begin by turning the main power switch to off.
  • Put on a pair of protective gloves to prevent any accidental injuries.
  • Place Automower® upside down, preferably on a sheet on a level surface.
  • Remove the bulk of any clippings and dirt using your fingertips.
  • Take an old toothbrush and gently clean the wheels, skid plate, body, etc.
  • Return Automower® to its original position, gently shaking out any debris.
  • Wipe down the chassis and all external body parts with a damp cloth.
  • Dry everything off with a microfibre cloth when done.
  • Turn on the main power switch and Automower® is good to go.

Ride-On/Zero-Turn/Garden Tractor

Husqvarna’s range of Ride-On Front Mowers, Zero-Turn Mowers and Garden Tractors all have different servicing needs, and it’s recommended you leave the bulk of the servicing and maintenance to a professional. However, there are a few things that you can do on a regular basis to keep your mower in good condition.

For mowers with inflatable tyres, make sure the pressure is kept at 16psi at all times. Checking them before use is a good routine to keep. Check the air intake valve before use and give it a clean out if it appears to be clogged; debris in the air intake can lead to an overheating engine which can cause serious damage. Check the mower‘s fluid levels before use each time. This includes oil levels, the hydraulic reservoir and radiator fluid. Top up any fluids that are low.

Check the air filter regularly. If it’s noticeably dirty or the dust load indicator has turned red, you’ll need to replace it, as a dirty air filter can lead to serious damage. Ensure the fuel filter is replaced after 800 hours of operation (at most). If you’re noticing the engine stuttering or if the fuel supply seems to be an issue, it’s a good idea to change the filter sooner.

The Husqvarna Dealer Advantage

When it comes to keeping your lawn mower in top condition, regardless of what kind you have, taking advantage of your local Husqvarna dealer’s experience and services is your best course of action.

What Oil Is Best For A Husqvarna Lawn Mower?

Husqvarna lawn mowers are a popular choice for many homeowners and business owners alike. But if you are a new owner, then you need to know the best oil to use for your Husqvarna lawn mower. Let’s take a look at what the manufacturer suggests.

Husqvarna recommends using full-synthetic 10w-30 oil in their lawn mowers. This blend of oil is perfect for push-behind lawn mowers, tractors, and zero-turn mowers. Whether it’s for residential or commercial use, this oil will provide the best engine protection.

No matter the engine, oil is vital to the proper functioning of your lawn mower. In this article, we will take a closer look at why this is the best oil for Husqvarna lawn mowers. In addition, we will answer other frequently asked questions about the maintenance schedule for Husqvarna mowers, so read on!

What Oil Should I Use In My Husqvarna Mower?

Husqvarna is known for manufacturing lawn mowers that provide high-level performance and power as well as long life. To ensure that your mower will remain operational for years to come, it is essential that you use the correct oil in your engine.

The manufacturer recommends using full-synthetic 10w-30 oil in all Husqvarna lawn mowers. This type of oil has been specifically designed to handle high temperatures and reduce engine wear.

Top 5 Ways To Fix A LAWN MOWER That WON’T START (Fix It In Minutes)

Not only should this oil be in your lawn mower, but it is also recommended to be used in Husqvarna tractors. If you are a business owner, using the best oil possible is especially important.

This is because you will be operating the equipment for extended periods of time. The higher-quality oil can help prevent any issues with your engine, so it is important that you follow Husqvarna’s recommendations.

Plus, most lawns are mowed during hot weather. If you don’t use the right oil, then your mower can overheat and cause serious damage to the engine.

For residential work, you may be able to get away with using cheaper oil. However, your mower may not last as long or perform as well as it should.

No matter what type of mower you use, always make sure to follow your manufacturer’s instructions when it comes to oiling and maintenance. Doing so will ensure that your Husqvarna lawn mower lasts for years without any issues.

How Often Should I Change My Oil In My Husqvarna Lawn Mower?

The oil change schedule for lawn mowers is different than for vehicles. For vehicles, you typically will change the oil by mileage or by so many months, whichever comes first.

Lawn mowers, on the other hand, go by hours or season. Husqvarna recommends changing the oil every 5 hours of continuous use or at least once per season.

You can either do the oil change yourself, or you can take it to a service center. Keep in mind that if you don’t use synthetic oil, you may need to change the oil more often since it can break down faster.

If you are interested in buying a used Husqvarna lawn mower, then ask the previous owner for the maintenance records. This will give you an idea of how often the oil was changed during their ownership.

If you do decide to do the oil change yourself, then check the oil capacity of your mower. Every mower is different, and overfilling with oil can cause problems with your engine.

Lastly, adding oil isn’t a substitute for changing the oil. You should still follow the same schedule for changing your oil even if you have to add some in-between changes.

How Much Does It Cost To Change The Oil In A Husqvarna Lawn Mower?

Before the next season starts, make sure to change your oil, air filter, and spark plug in order to keep your mower running smoothly. The cost will vary depending on the type of mower, the oil you use, and where you purchase it from.

On average, you can expect to pay 25-50 or more. This is a relatively inexpensive cost when you put it into perspective.

It is worth getting multiple price quotes and comparing them, as can vary between different service centers. If you are doing the oil change yourself, then you can save money by purchasing the oil and filter from a local store or online.

How Do You Change The Oil In An Husqvarna Lawn Mower?

Follow the steps below to change the oil in your Husqvarna lawn mower:

Prepare Supplies

You will need the following supplies to properly change the oil:

  • The proper amount of engine oil (refer to owners manual)
  • Oil filter
  • Drain pan
  • Oil funnel
  • Towels

Once you have the supplies listed above, you can continue to the next step.

Prep The Mower

Next, you will need to prep the lawn mower for an oil change.

  • First, run the engine until there is no fuel left.
  • Disconnect the spark plug and move the spark plug wire so it won’t come into contact with the spark plug.
  • Using a towel, clean the oil cap and filler spout.
  • Remove the oil cap and dipstick.

Remove The Old Oil

It may seem odd, but most lawn mowers have the old oil drained directly from the oil spout. When doing this, lay something down to avoid a mess.

  • Tip the lawn mower on its side and drain the oil into the oil pan.
  • Ensure all of the old oil is out of the lawn mower.
  • Then remove the old oil filter.
  • Add the new oil filter.

Add New Oil

Once all of the old oil is drained, it’s time to add the new oil. Make sure that you are using the proper type and amount of oil for your lawn mower (refer to the owner’s manual).

  • Using an oil funnel, slowly pour the new oil into the filler spout.
  • There will be a max fill line indicated on the oil cap, so make sure not to overfill.
  • Put the oil cap and dipstick back in place.
  • Tighten the oil cap until it is secure.
  • Wipe off any excess oil.
  • Replace the spark plug and reconnect the spark plug wire. It’s important to ensure that the plug is tight before starting up the mower again.
  • Start the lawn mower to ensure the oil is properly circulating.

If everything looks good, then be sure to dispose of the oil responsibly. Most automotive service centers and auto parts stores will accept used motor oil for proper disposal.

Remember, unless you just recently replaced the spark plug and air filter, you may want to consider replacing them as well.

Congratulations, you just successfully changed the oil in your Husqvarna lawn mower! Following these steps will ensure that your mower is running smoothly and that it will last for many seasons to come. Be sure to check the oil level again after a few hours of use and before storing it for the winter.

Do You Have To Use Husqvarna Oil?

Most dealers will recommend using their brand of oil for their machines. However, you don’t necessarily have to use Husqvarna oil for your lawn mower.

You can use any type of oil that meets the engine requirements listed in the owner’s manual. Just be sure to check what viscosity and grade are recommended for your specific model before making a purchase.

This is similar to vehicles when it comes to oil changes. For example, Lexus recommends using their Genuine Motor Oil, but you can still use other brands as long as they are within the correct viscosity and grade.

Should You Warm Up A Husqvarna Lawn Mower Before Changing The Oil?

It’s always a good idea to warm up an engine before changing the oil. If you run your Husqvarna lawn mower for 10-15 minutes to change the oil, you will ensure all of the impurities are out of the oil, and it will empty easier.

This is also a great time to check the air filter, spark plug, and other engine components for any signs of wear or damage. If any parts need attention, you can address them before putting the mower away or using it again.

Final Thoughts

Changing the oil in a Husqvarna lawn mower is an essential part of proper maintenance. Be sure to double-check your lawn mowers owner’s manual before changing the oil, as each model may have different requirements.
