I have a 1986 Wheel Horse 417 A Model 31-17KE 02 . It has a Kohler engine KT 17QS 24363 and Deck 05-48MS05. Originally, the blades stopped turning and the belts weren't moving. One of the bearings in the pulley was worn so I replaced it, but that didn't solve the problem. I then replaced the clutch plate, which was worn smooth. Now, the pulley adjustment is smoking and obviously overheating. Any suggestions as to what I should be looking at now for repair? Thanks, Joe
