More Information about Belts


First you should not be having to replace belts every year or more in a year. So here are things to look for before replacing that third belt this season.
A common problem especially with deck belts is belts being thrown off of their pulleys. There can be several reasons for this:

The most common problem with deck belts is excessive grass clipping on the deck. Grass clipping can work their way under pulleys and deck covers which can lead to more serious problems. Make sure to clean off your deck after every use following the manufacturers recommendations.

Here a big problem that is missed a lot. You know that guard around that pulley that makes it a pain to take off the belt every time! Well that guard is very essential in keeping the belt in place. Missing belt guards will cause the belt to fly off.

Last but not least pulleys can cause big problems. Check pulleys for wear and worn out bearings. If in doubt replace the pulley. Always remember to shut the unit off before attempting any maintenance on the unit. This brings us into the other problem "broken belts".
