:rolleyes: My mowing deck is breaking belts...the pulley seems to be fine? What could be causing this? Thanks.

Seized pulley

take the belt off and check all the pulleys look for any thing that could be seen as not running in line or with todays crap plastic every thing pulleys that are half missing bent spindlles or belt guides improperly adjusted look for wear in places it should not be and above all dont mow in places where a brush hog should be used good luck
