Got a call yesterday, friend tells me his crew leader called him and was having problems with the Bobcat. Asked me to look at it, so I call his crew leader, and I check out the mower. Tranny belt wouldn't stay on. Crawl under the mower, and see the pulley under the tranny is 1/2 inch higher then the tension pulley. Then I notice the tranny pulley is warped. It appears they have hit something, but how??? Only guess I have is that when they unloaded the mower, the Velke got buckled and got caught under the tranny pulley. Any suggestions?
