When to Replace Lawn Mower Belt (Drive Deck Belts)

The lawnmower belt(s) is the main component that helps drive the power from the engine to drive the propeller which cuts the grass.

Over time, general wear and tear will occur and the belt(s) will eventually wear out and potentially break or not be able to cut your grass as efficiently.

But when is the best time to replace it? We will also review how long they last and ways to make the belt last longer whether it be on a push, self-propelled or riding lawn mower.

When to Replace Lawn Mower Belt?

There are two different types of belts; a drive and deck belt. The deck belt is the main belt which helps drive the propeller to cut the grass. The drive belt is what helps move the mower on its own (self propelled or riding mowers).

If you have a push lawnmower (electric or petrol) this will only have a deck belt. The belt should last the lifetime of a typical lawn mower (8-10 years, if used in ideal conditions and properly maintained). However if in the situation the deck belt needs to be replaced you will find out the propeller doesn’t run and not cut the grass where this is the most obvious symptom (other symptoms are explained later).

If you have a self-propelled or riding mower, you will find an additional belt which is the drive belt. As it states in the name, this helps drive the wheels of the mower to move and will help drive the other components for the deck belt. These belts last between 3-4 years (again depends on the amount of use of the lawnmower) and should be replaced within this time period, but of course if the mower is still running as it should, the replacement will be put off but there are various signs and symptoms to indicate if the belt should be replaced which is explained in the next section.

How to tell if a mower belt is too worn?

There are easy tell-tale signs which show a worn mower belt, but how do you tell the difference between a worn (still ok to use for a fair few sessions) or a very worn belt (will most likely break in the next one or two sessions).

The best way to check is to visually inspect the belt and the upcoming signs are of belts which need replacing.

One obvious sign is whether the belt is shiny and completely flat with little to no ridges or bumps (depending on belt design) on the surface which fits into the grooves of the pulley system. Then this is the obvious sign of a worn belt that needs replacing.

Other signs are cracks in the actual belt itself. If you bend the belt the other way from its natural position and it splits open then the belt has been cracked and it won’t be long until it snaps.

If you find the belt quite slack between each pulley, this is also a sign of old age or wear and tear. This will not efficiently run the mower and will be more prone to slipping when mower is on. Don’t get confused if you have a feature to un-tension the belt on the mower which is normal depending on the design of your mower.

If it is particularly difficult to access the belt or you want a quick way to notice the belt is too worn, keep particular attention to your next mowing session. Some signs may include:

General signs:

  • Mower stops/stutters at times (as it has lost traction to drive the wheels)
  • Excessive vibration through the mower

When to replace self-propelled lawn mower belt

One key design of the self-propelled lawn mower is that it helps move the mower along which prevents you from having to push the mower, only requiring you to steer it in the direction of where you want to cut your grass. If you suddenly feel that you need to exert more force into pushing the mower or if the drive is slower than usual it is time to replace the drive belt. The last thing you want is the belt to snap as this can cause problems elsewhere if it gets caught or hits other components.

electric, lawn, mower, belt

When to replace riding lawn mower belt

Similarly to a self-propelled lawn mower, you will need to replace the drive belt from time to time, you will find similar symptoms to the self propelled lawn mower where the mower may not drive very well, the belt may slip and mower may feel it is stuttering while driving.

Why does my lawn mower belt keep breaking?

If you have recently broken your mower belt or just replaced your mower belt and the belt has broken in no time, there are reasons why this has happened.

One common problem is excessive cut grass clippings on the deck. These clippings can get caught in between the pulleys which the belts are directly driving. This will cause unwanted additional tension to belts and may cause stretching to the belt which will loosen and then more grass clippings could get caught and would eventually snap the belt.

Another problem could be an oil leak within the engine, this will simply destroy the belt. If you have recently replaced a belt and it has broken with little use of the mower, you should check for oil leaks.

Broken or faulty pulleys can also cause broken belts. The pulley is meant to spin freely as the belt gets pulled around it. If the pulley is not spinning freely, uneven or excessive friction will occur on the belt and consequently wear it out quicker. If the pulley doesn’t look broken it is worth checking the bearings as these may be worn and may need replacing.

If you have recently replaced your belts, it is important to tension the belt correctly according to your owner’s manual. If it has been over-tensioned, this will cause excessive strain on the belt when in use and will break quicker than usual. Misalignment of the belt to the sheave (groove(s) of the pulley) can also cause excessive wear, so make sure the belt grooves are aligned properly within the pulley, an easy way to check is if you spin one pulley the other pulley that the belt is wrapped around will move at the same time and frequency.

Checking the type of belt used in your mower is important especially if you are going away from what is stated in the owner’s manual. Factors such as the material, type of the belt and lengths are important and vital to ensure the belt lasts the intended lifetime they were made for. If you have purchased a belt that is not recommended within your owner manual but the design and lengths of the belt are correct the material is likely not to be the same as the original and most probably won’t be able to take the strain of the mower over its intended life.

It is worth noting some mowers only allow you to use the OEM (original equipment manufacturer) components, so no matter what belt you buy even if you match all the specifications of the OEM belt it may still not last as long as intended. However if in the case you can use other belts, use a belt which is made from Kevlar (often used in bulletproof vests), this is far more long lasting than the regular rubber reinforced with polyester cord belts. Although this is a more expensive option it might be worth using if it is particularly hard to change the belts depending on your mowers design.

How to keep lawn mower belt running for longer?

If you want to keep the replacement of the belts to a minimum these common procedures and guidance will keep the belt running for longer:

  • Remove grass clippings at the end of every session (check the deck and in between the pulley belt)
  • Use the mower for no longer than the recommended time, excessive heat will cause unnecessary wear the belt and weaken it over time
  • Check the tension of the belt as often as possible and adjust where necessary as according to your manual
  • Use the mower in the ideal conditions (dry and not completely over grown grass), if you are using it in conditions that are not ideal (wet and completely overgrown grass) it will wear the belt far quicker, if you do have very overgrown grass, trim it down first and complete the lawn in 2 sessions

The advice above is generic and covers all the mowers but of course refer to your owner’s manual and the recommendations of maintaining the mower as there may be extra/special features which may not be on regular mower that may need special attention which may affect the belts if not properly maintained.

Related Questions.

Do you have to remove mower deck to replace belt?

This will depend on the type of mower you have. On a riding mower the belt should be accessible at the deck when it has been lowered to its lowest position or if you can lift the mower to access underneath the deck. However, if you have a self-propelled or push mower, this may be more difficult as this is often covered and protected by casing, so yes you may have to remove the deck to replace the belt. A drive belt is more difficult to replace and you are more likely to need to remove the mower deck on older models. Newer models may be designed so that the drive and deck belts are accessible once the cutting deck has been lowered into the lowest position. Again with any maintenance ,check your owner’s manual.

How many belts does a riding lawn mower have?

Some texts state that a riding lawn mower will have 2 belts (drive and deck belt) whereas some refer to 3 belts (Power Take-off Belt (PTO) or Power clutch belt, Arbor belt and Drive belt). The PTO and Arbor belt is often referred to as the ‘deck belt’ as these are found within the deck which help drives the cutting propellers. These are different belts which is found in the same area but differ in lengths and use in the actual lawn mower. It is important to check your owner’s manual to ensure you differentiate between the two otherwise the mower won’t run as it should.

Why Is Your Electric Lawn Mower Smoking? 10 Causes

Are you mowing your lawn with an electric mower and noticing some smoke coming from the machine? It’s not just your lawn that’s in trouble – you could be doing damage to the mower, too. But why is your electric lawn mower smoking?

If your electric lawn mower is smoking, it could be due to an overheating motor. When the motor overheats, the insulation around the wires can break down, causing a short circuit. This can cause the wires to overheat and melt, emitting smoke.

This post will discuss ten potential causes of smoking electric lawnmowers. I’ll also give some tips on how to fix each problem so you can get back to mowing your lawn without any smoke. Read on to learn more!

The Motor Is Overheating

One of the common reasons why an electric lawn mower is smoking is because it’s overheating. When an electric lawn mower overheats, the motor can start to smoke.

Some of the things that can cause the motor to overheat include:

  • The motor is dirty: Over time, the motor on an electric lawn mower can get dirty. This can happen if you don’t clean the underside of the mower deck regularly. When the motor gets too dirty, it can’t cool itself properly and will start to overheat.
  • Something is caught in the blades: If something is caught in the blades of your mower, it can cause the motor to overheat. Be sure to check the blades regularly and remove any debris that may be caught in them.
  • The grass is too tall: If the grass is too tall, it can put a strain on the motor. That can cause the motor to overheat and start smoking.
  • The mower is old: An electric lawn mower that’s starting to smoke may just be old. Over time, the parts in the motor can wear out and cause it to overheat.

Here are a few signs that your mower’s motor is overheating:

  • The mower’s blades stop spinning.
  • The mower starts to smell like it’s burning.
  • The mower starts smoking.

How To Fix

If the mower is smoking because the motor is overheating, you’ll need to take it to a repair shop. The technician will be able to diagnose the problem and fix it.

Besides taking it to a repair shop, there are a few things you can do to prevent the motor from overheating:

  • Clean the mower regularly: Be sure to clean the underside of the mower deck and the area around the blades.
  • Check the blades often: Remove any debris that may be caught in the blades.
  • Don’t let the grass get too tall: Cut the grass when it’s no taller than 3 inches (7.62 cm).

The Motor Is Worn Out

Another common reason your electric lawn mower is smoking is that the motor is worn out. Over time, the motor will wear down and eventually need to be replaced.

Here are a few signs that your mower’s motor is worn out:

  • The mower doesn’t run as well as it used to.
  • The mower starts to smoke.
  • You’ve had your mower for a while.

How To Fix

If the motor on your lawn mower is damaged, it will need to be replaced. However, before you replace the entire motor, you should take it to a professional to have it inspected. They may be able to repair the damage and save you some money in the long run.

Besides, a new motor is a big investment, so you want to be sure that it’s absolutely necessary before you make the purchase.

That said, here are a few tips to help you choose the right motor for your lawn mower:

  • Choose a motor with the same voltage as your old one.
  • Choose a motor with the same manufacturer as your old one.
  • Choose a motor with the same model number as your old one.
  • Check the owner’s manual for compatibility.

The Mower Is Overloaded

Another common reason for an electric lawn mower to start smoking is that it’s overloaded. When a mower is overloaded, it can cause the motor to overheat and start smoking.

Some of the things that can cause a mower to become overloaded include:

  • The grass is too tall: If the grass is too tall, it can put a strain on the motor. Try mowing the lawn more often so that the grass isn’t too tall when you do mow.
  • The blade is dull: A dull blade can also cause a mower to work harder than it should.
  • You’re going too fast: Mowing too quickly can also overload the motor. Slow down and take your time when mowing the lawn.

How To Fix

If your mower is smoking because it’s overloaded, consider these tips to prevent it from happening again:

  • Try mowing the lawn more often so that the grass isn’t too tall.
  • Sharpen the blades on your mower.
  • Slow down when you’re mowing the lawn. Take your time, and don’t try to hurry through it.

There’s a Short in the Wiring

Another reason why the mower may be smoking is that there’s a short in the wiring. This can happen if the wires are frayed or damaged in some way, causing an electrical current to arc between them.

The current can create a lot of heat, which can then cause the insulation on the wires to start burning. In addition, a short circuit can also damage the electrical components in the mower, causing them to fail.

How To Fix

If the wiring on your lawn mower is damaged, it’ll need to be repaired or replaced. That said, before you start tinkering with the wiring, it’s important to disconnect the mower from the power source.

Once the mower is disconnected, follow these steps:

  • Inspect the wiring. If you see any damage, such as frayed wires or exposed insulation, it will need to be repaired or replaced.
  • Reattach any loose wires.
  • If the wiring is damaged beyond repair, you’ll need to purchase new wiring and have it installed by a professional.

You Have Worn-Out Blades

Another common reason for an electric lawn mower to start smoking is worn-out blades. When the blades on your lawn mower are worn out, they can cause the motor to overwork, which can lead to it overheating and smoking.

Additional signs that your mower’s blades are worn out include:

  • The mower isn’t cutting the grass well.
  • The mower is leaving streaks in the grass.
  • The mower is making a lot of noise.

How To Fix

If the blades on your lawn mower are damaged, they’ll need to be replaced. That way, you can be sure that they’re sharp enough to cut the grass properly without straining the motor and causing the mower to smoke.

However, be sure to check the manufacturer’s website or the owner’s manual to find the correct blade size and type for your model of lawn mower.

The Deck Has Accumulated Grass and Debris

The deck of your lawnmower is an important part of the machine. It helps to deflect grass and debris away from the blades and motors, keeping them running smoothly (source).

However, if you don’t clean the underside of the deck regularly, it can start to accumulate grass and debris. That can cause the motor to overheat and start smoking. In addition, it can make it difficult for the blades to spin properly, resulting in a less effective cut.

Here are the typical signs that it’s time to clean your mower’s deck:

  • The deck is visibly dirty.
  • Grass and debris are accumulating on the underside of the deck.
  • The mower is leaving clumps of grass behind.
  • The mower is leaving a trail of debris behind.

How To Fix

If the deck on your lawn mower is dirty, it’s time to give it a good cleaning. As I mentioned, a build-up of grass and debris can cause the motor to overheat and smoke.

Here’s how you can clean your lawn mower deck:

  • Switch off the mower and disconnect it from the power source.
  • Tip the mower onto its side so that you can access the deck.
  • Use a putty knife or a stiff brush to remove any built-up grass and debris.
  • Use a hose to rinse off the deck and remove any remaining dirt.
  • Allow the deck to dry completely before you use the mower again.

The Mower’s Belt Is Broken or Worn Out

Another common reason for an electric lawn mower to start smoking is a broken or worn-out belt. The belt is what drives the blades on the mower, so when it’s not working properly, it can cause the motor to overwork. That can lead to the motor overheating and smoking.

Additional signs that the belt may be the issue include:

  • The blades are not spinning.
  • The mower is making a squealing noise.
  • There is visible damage to the belt.

How To Fix

If the belt on your lawn mower is damaged, it’ll need to be replaced. The good news is that lawn mower belts are relatively inexpensive and easy to find.

Here are a few tips to help you choose the right belt for your lawn mower:

  • Check the manufacturer’s website or the owner’s manual to find the correct belt size and type for your model of lawn mower.
  • Be sure to measure the old belt before you purchase a new one. That will ensure that you get the right size.
  • If possible, take the old belt with you when you go to purchase a new one so that you can compare them side by side.
  • If you’re unsure about which belt to purchase, ask a sales associate at the store for assistance.

Note: For the best results, ask a professional to help you install the new belt. That way, you can be sure that it’s installed correctly and won’t cause any damage to your lawn mower.

The Discharge Chute Is Blocked

The discharge chute on your lawn mower is responsible for directing the grass clippings away from the blades and out of the back of the mower. However, if the discharge chute becomes blocked, it can cause the grass to build up under the deck. That can lead to the motor overheating and smoking.

Here are a few signs that the discharge chute is blocked:

  • The grass isn’t being discharged from the back of the mower.
  • The engine is working harder than usual.
  • Grass is building up under the deck.

How To Fix

If the discharge chute on your lawn mower is clogged, it’s time to clear it out.

Here’s how you can clear a clogged discharge chute:

  • Switch off the mower and disconnect it from the power source.
  • Remove the discharge chute from the mower.
  • Use a garden hose to rinse out the discharge chute and remove any built-up grass or debris.
  • Reattach the discharge chute to the mower.

Caution: Be sure not to tear or damage the discharge chute while you’re clearing it out. Otherwise, you’ll need to replace it.

The Mower Is Old

Another potential reason why your mower is smoking is simply because it’s old. Like any other machine, lawn mowers have a lifespan. And after a certain amount of time, they just aren’t able to work as well as they used to. So if your mower is starting to smoke, it may be time for an upgrade.

That said, here are the tell-tale signs that your mower is on its last legs:

How to Start an Electric Lawn Mower

  • It’s hard to start.
  • It doesn’t run as smoothly as it used to.
  • It’s leaving clumps of grass behind.
  • It’s smoking.

That said, be sure to check out When To Replace a Lawn Mower (and How To Choose) for more information on how to tell if your mower is due for an upgrade. Besides, the article provides some great tips on how to choose the right lawn mower for your needs.

How To Fix

If your lawn mower is smoking and you can’t figure out why, or it’s just not working properly, it might be time to buy a new one.

While it’s certainly not the cheapest option, it will save you the hassle of trying to repair an old mower. Plus, you can be sure that a new mower will be more reliable and won’t cause any smoking problems.

electric, lawn, mower, belt

When you’re shopping for a new electric lawn mower, be sure to read the reviews. That way, you can find one that’s right for your needs and won’t have any smoking issues.

In that case, a lot of folks have been pleased with the EGO Power LM2101 21-Inch 56-Volt Lithium-ion Cordless Lawn Mower (link to Amazon). It provides up to 45 minutes of uninterrupted runtime and has a 21-inch cutting deck for a fast and efficient mow.

You’ve Been Mowing for Too Long

Finally, an electric lawn mower to start smoking if you’ve been mowing for too long. Remember, these machines are not built to run for hours on end. So if you’ve been mowing your lawn for an extended time, it’s not surprising that the motor would start to overheat and smoke.

How To Fix

If you’ve been mowing for a while and the motor starts to smoke, the best thing to do is to take a break. Turn off the mower and let it cool down for a few minutes. Once it’s cooled off, you can start mowing again.

That way, you can avoid damaging the motor and prolong the life of your mower. Besides, a little break can do you some good too.


An electric lawn mower can smoke due to many factors. A common cause is that the motor is overheating. However, there are a few other potential causes, such as a clogged discharge chute or old age.

If you’re having trouble with your lawn mower smoking, the best thing to do is to call a professional for help. They’ll be able to diagnose the problem and make the necessary repairs.
