How to Replace a Lawn Mower Belt

Life is full of chores and lawn mowing is one of them. However, many find lawn mowing cathartic. Strolling around the front or back lawn, listening to music or just the sweet sounds of summer, and getting the house looking a bit neater.

For lawn mowing to go well, you need to keep your mower in a good condition. If you are having trouble with your lawn mower belt slipping, then it sounds like it’s time to replace it. Replacing the belt on your lawn mower can be intimidating, but with a few steps and supplies, you will have your machine humming along again in no time.

Buying a Lawn Mower Belt

Firstly, use a reliable company like Industrial & Automotive Parts to buy the right belt for your lawn mower. They offer a great selection of quality belts that are designed to last. Find an exact match for the model and year of your lawn mower so you can be sure it will fit properly.


Now it’s time to prepare your lawn mower for replacement. Make sure to unplug it from the power source to avoid any risk of electrocution and then turn it over so you can access the underside. Remove all debris, dirt, and grass clippings that may be caught in the blades or stuck to the deck with a stiff brush or shop vacuum.

Removing the Old Belt

With the mower prepped and ready, it’s time to remove the old belt. Depending on the model of your lawn mower, you may need to take off a protective cover or guard to access the belt. Check your owner’s manual for specific instructions here as different models have different configurations. Once you have access to the belt, use a screwdriver or ratchet wrench to loosen and remove the bolts that connect it in place.

Installing the New Belt

Now that you have the old belt removed, it’s time to install your new one. Place the new belt on the pulleys, matching up all of the grooves and ridges. Make sure you’re following your manufacturer’s instructions for the belt routing and that the belt is snugly in place on each pulley. Once you have everything positioned correctly, use your screwdriver or ratchet wrench to secure all of the bolts again.

Testing Your Work

The last step is to make sure your new belt is working correctly. Reinstall the cover, plug in the power cord, and start the engine. If you hear any chirping from the pulleys or notice any slippage on the belt then you may need to go back and retighten some of the bolts. Otherwise, you should be all set.

Is it Difficult?

Replacing a lawn mower belt is usually not a difficult job, but it can be time-consuming. It’s important to take your time and follow all of the instructions carefully so that you get the best performance out of your new belt. With some patience and practice, you should be able to easily replace your own belt in no time. This will save you time and money by avoiding a trip to the mechanic. Give it a try yourself and see what you can do.

If you need help, remember to look at the instruction manual – YouTube is also great for discovering tutorial videos. Alternatively, you can always call a professional if the job proves to be too difficult. Even when working with a professional, it’s important to make sure that all of the steps have been taken correctly to ensure the best performance from your lawn mower!
