Preventing Grass Clippings From Clogging Your Mower

One of the most frustrating aspects of mowing your lawn is the grass clippings sticking under the deck or clogging the bagger chute. I’d like to tell you that there’s a fix that can avoid the need to actually clean under the deck and the chute by hand, but I can’t. However, you can make it less of a problem by using a lubricant on the deck after you clean it.

Why Grass Clippings Clump When You Mow

When you mow your lawn a push mower creates masses of little grass clippings that fall onto the lawn. When the grass is wet or too long the clippings fly up and stick to the underside of the deck and blade. The bagger chute can also be affected.

The clinging clips can cause the mower’s blade to dull and can cause the blade and the area under the deck to rust. This could happen because the grass is wet due to a previous shower or thunderstorm. However, this can also occur in hot and dry climates because grass retains moisture. Some times the rust can cause enough damage to the metal of the mower that you’ll have to replace certain parts.

The lawnmower losing suction can also cause grass clipping to clog the chute. A good sign that this is occurring is that the bag that catches the clipping doesn’t get as full as you would expect and it takes longer to mow. In this case, the bag may be unaligned with the chute causing debris to collect and ultimately clog the system.

The mower’s engine can also contribute to the problem. If the engine is worn, it may work harder than normal. The strain can wear out the engine even more and could result in the need to acquire a new mower. A well-maintained engine will allow you to run it at full throttle and can minimize the accumulation of the clippings.


The use of lubricants including WD40, TITESEAL, non-sticking cooking spray, Teflon, or Silicone can break down large accumulations of clippings and could prevent rust. However, the blade and the deck need to be clean before you spray these formulas onto the mower.

Cleaning Under The Deck, The Chute, And The Blade Of The Mower

The process of cleaning the mower involves:

The Inspection

The process of inspecting the under side of the deck and blade can be difficult or not depending on the type of mower you’re using –- a push mower or a riding mower.

When it comes to a push mower, you need to consider the location of the gas and oil tanks. Both are commonly located on the top of the mower. To inspect the under side of the mower, you will have to tip it over. Notice the exact location of the gas and oil tanks before you tilt the mower. Make certain that the gas and oil tanks are securely closed. It may be best to be cautious and empty the gas and oil tanks before tipping the mower to ensure that there is no spillage onto your lawn or driveway.

For riding mowers, you will have to be familiar with removing the cutting deck. This can be a bit tricky. Each brand’s model has a similar configuration, but instead of guessing, it’s best to refer to the owner’s manual before undertaking the task. Place the deck on wooden blocks to relieve tension and so that you can work more efficiently. The cutting deck of a riding mower is heavy and so you may not be able to handle it by yourself. It’s best that you enlist the assistance of someone else.

Be sure to either block the blade with a wooden block or take off the blade if you are dealing with a push mower to avoid cutting yourself.


Once the under portion of the deck is exposed, scrape off the grass debris with a screwdriver, or a paint or putty scraper. If the debris is caked on fairly securely, then loosen it by spraying the deck with a detergent or some kind of solvent. Once the area has been treated, let it sit for a while before you start scraping the clippings.

Wash And Rinse

The wash and rinse process requires a garden hose that is connected to a faucet. You may need an adapter on the hose to perform the washing process.

If you’re dealing with a push mower, then after you have done a thorough job scraping off the deck, you’ll need to wash and rinse the area. Collect a towel or sponge to scrub away any excess debris. You know you’re done when you observe clean metal all the way around the blade. Don’t worry about a few clippings that may remain. They won’t damage anything.

If you have a riding mower then follow these steps:

Locate the mower’s wash port. It is a small connector on the topside of the deck.

Connect the hose with an adapter to the wash port of the mower.

Lower the deck to the lowest position to keep the water inside. This will allow the cleaning to be more efficient and thorough.

Turn on the water and the mower. For the wash port to work properly, the blade must be spinning. This helps to disperse the water through and out of the deck. You will need to sit in the seat to start the engine and you’ll have to stay put for a few minutes to assure that there is a thorough cleaning.

Once the deck and blade are clean, turn off the mower’s engine as well as the water.

Once the deck and blade are dry, apply the lubricant. The lubricant will allow you to wait longer to clean the mower.

There are a number of things you can do between washings to assure that the under portion of your mower stays clean. They include:

Don’t mow when the grass is wet due to rain. It’s best to wait until the driest part of a day to take on the task of mowing the lawn.

Use a high-lift blade. These blades will accelerate the circulation of the clippings so that more of them land in the grass catcher or bag or back on the lawn.

How to Install a Side Discharge on a Lawnmower?

All mower owners have the same goal, to make their lawns look fresh and tidy. But not all environments are similar. Some have a big yard, and others have a small yard. Some yards are flat, and others move up and down and have steeper slopes. Also, the frequency of mowing and the type of grass can be different. Depending on your situation, you need a lawnmower that fits your specific environment. If you often have to cut tall and thick grass, you need a mower to cope with this. Many lawnmowers have problems with this type of grass and will get slow and inefficient. When the grass is slightly wet or damp, this problem is even more apparent. Using a proper discharge system will significantly help. In this case, using a side discharge on your lawnmower will ensure a much better grass discharging.

How to install a side discharge on your lawnmower:

  • Step 1: Securely turn off your mower.
  • Step 2: Locate the area where the discharge chute is to be installed.
  • Step 3: If applicable, remove the bolts that are already present there. If you are replacing an old side discharge, unbolt and unhook the old discharge chute.
  • Step 4: Pull up the mulch plug.
  • Step 5: Install the side discharge.
  • Step 6: Lower the mulch plug.
  • Step 7: Make sure that the side-discharge is firmly attached.

The procedure is relatively simple, and it’ll take you around 30 minutes max to complete this procedure.

This blog will explain how to install a side discharge in more detail and look at the advantages and disadvantages.

What is Side Discharge?

Mowing is more comfortable when the grass is not too tall and thick. If you have to cut tall and thick grass, you will notice that your lawnmower will have more difficulty. It is slower and requires more engine power. waste gets stuck in the mower’s cutter with larger grass, increasing the friction and making it need more power or go slower. When the grass is slightly wet or damp, this problem is even more significant. But there are solutions for this problem, using a side discharge.

A side discharge will provide a proper channel for the outflow of grass debris and ensure that the cutter area doesn’t get filled with grass. With a side discharge attached to your mower, grass waste will be thrown out towards a side, close to the blades. If you use a backend discharge system, where the grass is collected in a container on the back, the grass needs to follow a much longer path. Particularly with slightly wet grass, this path is even more challenging to follow, and often the cut grass will get stuck somewhere.

Installing a side discharge is easy to do, so you don’t need to take your mower to a mechanic. You can perform the installation yourself. It should take you no more than 30 minutes. Consulting the manufacturer’s manual or an online tutorial will also help.

Tools that You’ll Need:

You’ll need two main tools in this entire procedure. These are:

  • Side-discharge Bolts and hooks: You need to ensure that the side-discharge gets firmly and adequately attached to the mower. For this, you’ll need the bolts and hooks that came with the side-discharge so it can be attached to the mower.
  • A socket wrench: You’ll need a socket wrench to loosen or tighten the bolts.

How to Install a Side Discharge on Your Mower step by step:

Follow these simple steps to get the job done:

Step 1. Preparation:

Park your mower on an open flat area. Make sure the lawnmower is turned off. In the case of an electric lawnmower, you should unplug the power cord. In case of a gas lawnmower, make sure that the mower cannot accidentally turn on, as you will be working close to the blades during the installation procedure.

Using Safety gloves is a good idea to protect your hands from getting cut by sharp edges or the lawnmower blade.

Step 2. Press the Chute Downward:

There is a bracket that crosses that deck’s bottom on your lawnmower. You must make sure that the side-discharge is below this bracket. To meet this requirement, press the bottom side of the side discharge chute downward.

Step 3. Attach the Rubber Strap to the Deck:

To ensure that the side-discharge gets firmly attached to the deck, extend and attach the chute’s rubber strap to the deck.

Step 4. Locate the Installation Area:

Now you’ll need to locate the area on the deck where the chute is to be attached. Visual inspection would be enough in this regard, but you can still consult the user manual for locating this area.

Step 5. Remove the Bolts:

The area allocated for installing the discharge chute will have bolt holes. If there is an old discharge chute that you are replacing, you’d see that it is held in place with bolts. Remove these bolts using the socket wrench.

Step 6. Install the Discharge Chute:

The discharge chute might be covered with a mulch plug. Pull the mulch plug upward and install the discharge chute. Attach the discharge chute’s hooks to the mulch plug’s grip carefully. Tighten all the bolts using the socket wrench, turning it clockwise for tightening. Make sure that all the hooks are locked and all the bolts are tight.

Step 7. Test the Side Discharge Chute:

If the discharge chute is not firmly locked to the deck, it can remove itself during the mower’s operation and potentially damage even the blades. To avoid this situation, make sure that the discharge chute is attached firmly. You can check it by giving a jerk to the chute with your hand. If it is tightly locked, it won’t fall off. If it does, it means that you missed a bolt or a hook or attached it wrongly.

Step 8. Lower the Mulch Plug:

Once you have confirmed that the side discharge chute is firmly attached to the mower, carefully lower the mulch plug. You have completed a side discharge installation process with this step done, and your mower is ready for use.

Things You Should Know:

Now that you know how to install a side discharge on your lawnmower, there are several other things useful to know:

  • Removing the side discharge: Say you need to remove the discharge chute that you just installed. You can do so by opening a few bolts and unhooking a few hooks.
  • Turning the mower: Now that your mower has a side discharge chute attached to it, don’t turn it like you used to before. If you need to turn your mower, make sure that the side discharge chute is well set and does not carry the mower’s weight during the turn.
  • Please turn off the mower before install or removing: We cannot stress this point enough. Your mower must be turned off when you are installing or removing a side discharge chute. This is to avoid injury to any persons or harm to your mower.

Advantages of a Side Discharge Installed on Your Mower:

Installing a side discharge on your lawnmower has the following advantages:

How to prevent your lawn mowers grass chute from clogging.(We tested it out)

  • Clean cutting area: With the side-discharge attached, grass debris will not get caught in the cutting area, keeping it clean.
  • Clean blades: The side discharge will ensure that the blades stay clean for longer, increasing blade life and efficiency.
  • Cutting tall grass: A side-discharge attached to your lawnmower will allow your mower to cut taller and thicker grass—something difficult without the discharge chute.
  • Speed and efficiency: Ultimately, your lawnmower’s speed and efficiency will increase with a discharge chute attached.

Disadvantages of a Side Discharge Installed on You Lawnmower:

A disadvantage from using a side discharge could be that if you do not use a side discharge chute, the grass will be sent flying out the mower’s side. If you use a side-discharge chute, you will collect the grass, but the chute is often smaller than if you collect the grass in the back container. This means you have to empty it more often. And where this is easy to do with the container at the back by just reversing and pull a handle, emptying the chute takes more time.

The mower with a side-discharge will be wider than using the container in the back. Particular with the chute attached. So if you have a situation with narrow locations, it can difficult.

Final Remarks:

Using your lawnmower to cut bigger and thicker grass is difficult. With the increased grass debris getting caught in the cutting area and getting attached to the blade, the cutter speed will decrease, and the mower’s efficiency too. This means you’ll be spending more time and effort on the mowing process. Furthermore, you’ll have to clean the cutting area more often. Or, you can avoid all these problems by installing a side discharge on your lawnmower. A side discharge will allow the grass debris to move out toward a side instead of getting caught in the cutting area. This will increase the speed and efficiency of your mower. Installing a side discharge chute is not difficult. Following the step by step guide provided in this article, you’ll be able to install a side discharge on your mower in less than 30 minutes and enjoy faster mowing.

Lawnmower Chute Clogs – Fix Easily in Seconds

Unless you take a lot of pride in keeping your garden or yard neat, you probably don’t exactly enjoy mowing your lawn. However, whether you love it or despise it, there is one issue that no one wants when mowing their lawn, and that is a clogged mower chute.

A clogged mower chute can make a mess and be tricky to deal with, so it is best to get it sorted out as soon as possible and permanently if possible.

Fixing a clogged mower chute is as easy as switching off the mower and removing the clogged grass from the pipe and catcher. Additionally, you can help prevent your chute clogging by ensuring that you do not cut wet grass, your blade is sharp, and you’re not trying to cut too much length at once.

lawn, mower, grass, install, side

Though fixing a clogged lawnmower chute is easy, it is still an added step in keeping your lawn neat that no one wants to need to do.

For this reason, there are a plethora of tips you can find online or from gardeners or garden-keeping enthusiasts.

Below you will discover how to de-clog your lawnmower’s chute, why it clogs regularly, and how to prevent clogging.

How To Clear A Clogged Lawnmower Chute?

Clearing a clogged lawnmower chute isn’t tricky, but if you have a new lawnmower or haven’t needed to mow the lawn before, you might be able to use some tips if this happens to you.

Before preventing this from happening again, it is essential to ensure that your lawnmower is clear and working correctly.

Below is an easy-to-follow list of steps to help you clear your lawnmower chute right.

Clearing A Walk Behind Lawnmower Chute

  • Ensure that the lawnmower is off – It is first essential to ensure that the lawnmower you want to clean is off and disconnected from power if it is electric. If you want to be extra safe, you can disconnect the spark plug for a gas mower.
  • Disconnect the grass-catching attachment – Before continuing, it is essential to disconnect the grass catcher from the rest of the mower.
  • Lay the lawnmower on its side – Next, you need to lay the lawnmower on its side to give you easy access to the bottom of the mower.
  • Use a hose to clean the bottom – With easy access to the bottom of the lawnmower, use a high-pressure hose to wash off any grass or grass particles from the bottom of the lawnmower.
  • Clean the grass catcher – After cleaning the rest of the lawnmower, you can clean the catching attachment with a stiff brush and some soapy water.
  • Let the mower dry and reassemble – After cleaning all the different parts of the lawnmower, you can let it dry and reassemble it for further use.

Clearing A Riding Lawnmower Chute

  • Clean the bottom of the mower – For riding lawn mowers, there is usually an area where you can connect a hose. Once the hose is connected, let the blades spin at full power to distribute the water and clean the bottom.
  • Disconnect the chutes and catcher – Once the bottom of your riding lawn mower is clean, you can disconnect the tubes, disassemble the pieces, and disconnect the grass-catching attachments.
  • Clean the cutes and catcher – With the chute disconnected and disassembled, you can clean them. You can wash both the chutes and catcher attachment with a hose or some soapy water and a stiff brush.
  • Let the parts dry and reassemble – Once everything is clean, let all the pieces dry before reassembling. Once everything is dry and reassembled, you can continue to use your riding lawnmower.

How To Prevent Lawnmower Chutes From Clogging?

Now that the lawnmower is clean and clog-free, it’s time to discuss how to prevent your lawnmower’s chute from clogging again.

Though not all of these tips will work, many get passed down from one to another, and a lot of this information is good to know if you apply it to your mowing process.

Don’t Cut Wet Grass

The first and most likely reason your lawnmower chutes might be getting clogged is because of wet grass.

Because grass is relatively light, when the grass is moist, it can stick to surfaces such as the chute walls or the entrance to your catcher.

To prevent grass from clogging your lawn mower’s chute, ensure the mower itself is dry, and the same for the grass.

It is best not to trim the lawn directly after rain or after watering, as this is more likely to cause the grass to stick and cause a clog.

Don’t Do A Rush Job

Another reason why your lawnmower might have clogged shoots is because you are cutting too much grass per pass.

The more grass you cut, the heavier the load gets, and that means that the airflow could become too weak to push the grass into the catcher and cause a clogged lawnmower chute.

You should never cut the grass with more than one inch per pass to be safe. This length means that you should go over the same grass area a couple of times if the grass is very long, but it will help prevent a clogged chute.

Make Sure The Blades Are Sharp

When working correctly and in good shape, Lawnmower blades serve two separate functions on a lawnmower.

The first function is to cut the grass evenly and accurately.

The second function is to push, direct, or blow the cut grass down the chute and into the grass catcher attachment.

For this reason, if your blades are dull or otherwise damaged, there is a high likelihood of your chute clogging.

This possibility elevates because the grass does not flow through the chute to the grass-catching attachment, causing a pile of grass to gather in the pipe until none can flow through.

Keeping your lawnmower blade in good shape is essential to prevent chute clogs.

Clean Your Grass Catcher Or Grass Bag

If you are using a grass catcher or grass bag, a certain amount of air flows through the bag or catcher. The air pushed into the catcher while carrying grass needs to escape through a vent or small holes in the bag.

If grass blocks the vent, the air has no place to go, making it harder for the airflow to carry the grass through, causing the chute to become blocked.

It would be best to keep your grass bag or catcher clean to ensure that the chute will not clog due to inadequate airflow.


There are many reasons why your lawnmower could have clogged chutes. Luckily, most solutions and preventative measures are easy to do and maintain.

If you want to get the best experience from your lawnmower, I recommend keeping your lawnmower clean, the blades sharp, and never cutting wet grass or cutting too much on a single pass.

Why Is My Lawn Mower Spitting Out Grass? Causes and Fixes

The question “Why is my lawn mower spitting out grass?” will surely be running across the minds of gardeners who encounter this for the first time. It is normal to worry about grass flying in all directions while cutting grass on the lawn.

Mostly this could be due to faulty or clogged mower parts or because you are cutting wet and long grass. Read on as we have compiled all the reasons causing this problem along with their potential solutions.

  • Why Does Your Lawn Mower Spit Out Grass?
  • – The Grass Might Be Too Long
  • – Your Grass Might Be Too Wet
  • – The Blade Is Blunt and Dull
  • – The Mower’s Grass Chute Is Clogged
  • – The Mower Deck Is Dirty
  • – Grass Bag Under the Mower Is Wet or Loose
  • – The Tires Are Under-inflated
  • – Air Filters Are Dirty
  • – Mow the Grass Only When Dry
  • – Sharpen the Blades Well
  • – Clean the Clogged Chute
  • – Clean the Mower Deck
  • – Keep Your Tires Evenly Inflated
  • – Clean the Air Filter
  • – Don’t Allow the Grass To Grow Too Long

Why Does Your Lawn Mower Spit Out Grass?

Your lawn mower spits out cut grass pieces that begin flying around during mowing because you are cutting grass that is too long or wet, using dull mower blades, or there is a blocked grass chute. Other reasons include a dirty mower deck or the grass bag being loose.

Find out even more reasons in the list that we have compiled below.

– The Grass Might Be Too Long

Allowing grass to grow too long can be problematic for the lawn mower. These long blades often get stuck in the blades of the mower and the mower deck. The poor machine will have to exert double the effort and start spitting out grass clips.

Long grass continually clogs the mower blades, and you will have to keep stopping again and again to clean it. It will take a lot longer to cut tall grass and then later to clean the grass clippings from the lawn.

– Your Grass Might Be Too Wet

Mowing wet grass with any machine is never a good idea, generally. The wet grass clippings get clumped together and are spat out by the mower. These clumped-together clippings also become stuck to the mower blades and slow down the working of the blades.

This might not harm your mower but it uses more energy than usual. Wet clumps are also spat out into the mower deck and become stuck. After each mowing session, cleaning the deck will take you twice as much time. The grass that is spit out will also form clumps on the lawn, and you must clean it with double the effort.

– The Blade Is Blunt and Dull

The problem with a dull and flattened mower blade is that it needs to cut grass evenly. Mower blades are designed to spin and create a suction that pulls the blades straight up. This helps cut the grass faster and more neatly.

When the blade is dull from frequent use without sharpening, it will cut unevenly. Uneven pieces of cut grass are thrown around more than even grass. The suction created by the blades is also insufficient; hence the clippings are spat out instead of being collected in the collection bag.

lawn, mower, grass, install, side

– The Mower’s Grass Chute Is Clogged

The grass chute is a pathway through which the grass clippings are redirected into the bag in which they are collected. A clogged chute will redirect the cut grass toward the mower blades.

There are many reasons a chute gets blocked up and spits grass. The main reasons are cutting grass that is very tall or still quite wet. Sometimes, when the grass is being mowed extremely low, it can kick dirt into the chute and block it.

People who rarely clean their mowers will also face this problem because their unclean decks will end up choking the chute.

– The Mower Deck Is Dirty

We have said this before, and we will say it again: you need to clean the mower decks on the underside of your mower regularly. The cut grass pieces and dirt and soil are continually stuck there and form a thick carpet of debris.

If you go years without ever cleaning the underside of the mower, the deck will eventually have no more space and will start spitting out grass. You need to turn the mower over and see if a layer of grass has adhered to it.

– Grass Bag Under the Mower Is Wet or Loose

See that bag under the mower collecting all the cut pieces of grass? This grass bag might be responsible for all that grass being thrown around. This might happen if this bag becomes wet or gets contaminated with moisture. This contamination occurs mostly whenever someone uses the mower on a wet lawn or during a downpour.

When this bag is not attached properly and just loosely hanging under the machine, grass will spin around instead of being collected into the catcher bag. It would help if you ensured that this bag was dry and properly attached before each use.

– The Tires Are Under-inflated

When one or more mower tires are underinflated, they will lose their balance. The cutting blade present underneath also gets tilted. Imbalanced blades will always cut grass unevenly and get spit out more than ever. You can easily tell when the tires need to be filled with air again by looking or tapping at them.

– Air Filters Are Dirty

A lawn mower spitting grass might be due to a dirty air filter. The main function of air filters is to clean and filter out the air and exhaust. This filter gets covered by dust, debris, and grease over time.

If this carries on for too long, the proper working of your mower will be seriously affected and it will start spitting out grass. Regularly cleaning the air filters is an important aspect of lawn mower maintenance, and you must be vigilant.

How To Stop Your Mower From Spitting Out Grass?

To stop your push-type or riding lawn mower from spitting out grass easily, you should fix any problem with them and take regular lawn mower maintenance very seriously.

Make sure to mow the grass only when it’s dry and sharpen the mower blades well.

– Mow the Grass Only When Dry

Make a mental note to always cut your grass when it is as dry as possible. This means no more mowing right after rainfall. Wait for at least one to two days after each rain spell, as this is how long it takes for grass to dry up properly.

The grass might dry up quickly if you live someplace hot and sunny. Refrain from watering your lawn a day or two before you plan on mowing it. Watering the lawn right after mowing is beneficial in more ways than one.

While mowing early in the morning might seem like a good idea, the grass is usually not dry at this point. Allow the sun some time to evaporate the dew drops present on grass blades, and then take your mower to it.

– Sharpen the Blades Well

Every time you cut grass, you need to clean the blade afterward. Most mower companies suggest that a blade needs to be sharpened after approximate use of every 20 to 25 hours. How much you use your machine will determine how often you need to sharpen it.

Always turn the mower off and disconnect the spark plug to prevent it from starting accidentally while your hand is near the blade. You should also drain the oil tank and store that oil for a refill later. Very carefully tilt the mower on its side but in such a way that it is stable and will not fall over.

Loosen the nuts or bolts to remove the blade from the mower, keeping in mind which side is up and which is down. Clean the blade off any debris using a dishwashing soap solution first. The easiest tool to sharpen a blade is an electric angle grinder.

Keeping it stable, sharpen it at an angle of no more than 45 degrees. Ensure that both sides of the blade are well-balanced before reinstalling the right side.

– Clean the Clogged Chute

Turn the mower’s power off and disconnect its spark plug to be safe. If it is an electric mower, then turn its power off beforehand. The mower parts that catch grass underneath the mower are easily removable by hand.

Next, lay the mower on its side with the fuel tank facing upwards to gain access to the deck belt containing the chute. You must use a hose to clean the stuck grass and debris from the mower deck and the blade.

Use a stiff straight brush with a long handle to reach the chute. With the help of this brush and the water hose, clean the chute. Clean the grass catcher bag and allow everything to dry before reassembling the mower.

– Clean the Mower Deck

Ensure the spark plug is disconnected and the switch is turned off before turning the mower over to its side while keeping it balanced.

Use a water hose and soap water to clean the deck until it is spotless. If the layer of debris is too thick to be removed with even pressurized water, then use a gardening knife to scrape it off. Allow the entire deck to dry well before you start the engine again.

– Keep Your Tires Evenly Inflated

If any of your tires get deflated, refill them immediately. If you don’t have the refilling equipment home, take it to the nearby gas station instead. Take care that all the tires are filled at equal pressure; otherwise, the balance of the mower will again be disturbed.

– Clean the Air Filter

The great news is that you can clean your filter by yourself pretty easily. Put your mower to a halt and turn it off. It helps to disconnect the spark plug to ensure the machine does not start even by accident.

If you have trouble gaining access to the filter, refer to the machine’s instructions manual. It is covered by a shroud that must be unscrewed first and removed. Take the air filter out of the mower and see if it needs to be cleaned or changed. Some filters made of paper can just be cleaned by tapping them on a flat surface.

lawn, mower, grass, install, side

The foam air filter needs to be washed properly using soapy water. It will take a long time for this filter to dry properly, and you must wait all that time before reinserting the filter back in.

– Don’t Allow the Grass To Grow Too Long

Do you see how low the cutting blade of lawnmowers is located? These machines are designed to keep the grass at a particular length only. You must keep cutting your grass regularly to ensure it doesn’t clog your machine.

It is highly essential to keep an eye on the growth rate of the grass you are growing. Fast-growing grass types need to be cut several times per month during growth. Slow-growing grasses need to be cut much less often in comparison.


Let us end this guide on lawnmowers spitting out grass pieces by reiterating the most important points.

  • Never use your mower on wet grass or grass that is too tall, even if you have the larger riding type of mowers.
  • If the grass catcher is loose or wet, or the chute is clogged, cleaning it would stop the lawnmower from spitting out grass.
  • Keep the mower deck and the air filter regularly clean to prevent spitting.

Go through our list to determine why your mower is spitting grass out every time you take it out. We have also provided the easiest solutions so you don’t have to go anywhere else!
