Mower Deck Belt Keeps Walking Off the Pulleys? What to Check?

Look for bad routeing, worn pulleys, broken belt guides or bad tension. Once you have fixed the underlying problem, then you should replace the belt to prevent it from coming off again.

Why is the 42” deck specification important when choosing this replacement belt?

Worn or stretched belt may result in reduced blade speed, slipping, inconsistent blade engagement and uneven cutting. Replacing a damaged belt can help bring back the stable operation of the mower deck.

What do I do with the mower deck to get this new belt on?

With the engine off and the ignition key removed, clear debris from the deck and inspect the pulleys, belt guides, and tensioning system for wear or damage. Be sure the belt is seated properly in each pulley groove before returning the mower to service.

This belt is for John Deere D130, D105, E100, L100 and L110 models with 42-in deck. Always check the mower model and OEM belt number before ordering.
