Why Do My Mower Belts Keep Breaking?

Do you find yourself replacing your mower belts every year? If so, something is most likely wrong. You shouldn't need to replace belts every year, or more in one year.

There are a variety of causes for belt breakage. We recommend taking a look at these listed below to determine the cause your belt issues. Please contact us directly with any questions regarding your mower belt or if the cause of your belt breakage doesn't appear to be one of the following:

Excessive Grass Clippings
A common cause of belt breakage is excessive grass clippings on the deck. Grass clippings can work their way under pulleys and deck covers, causing series problems. Make sure to clean off your deck after every mower use and follow manufacturer recommendations.

Missing Belt Guards
Belt guards are crucial to the proper function of your mower. The guard around the pulley can be a pain to take off the belt every time. However, that guard is essential to keeping the belt in place. A mising guard will cause the belt to fly off.

Pulley Wear and Tear
Check pulleys for wear and worn out bearings. A pulley rides on bearings that allows it to spin freely. When a pulley doesn't spin freely, friction is created between the pulley and belt, causing the belt to break.

When in doubt, replace the pulley. Always remember to shut the unit off before attempting maintenance on your mower.
