My Cub Cadet zero turn Z-Force 44 with around a 20 horsepower Kohler engine wants to destroy the primary mower deck drive belt just about every time you use the mower. This would be the belt from the electric PTO clutch on the engine crankshaft to the center arbor on the mower deck. Today I put a new belt on it and mowed for 20 minutes in relatively light blue grass. Eventually I smelled something hot, stopped for a couple minutes and after starting again it snapped. The blue Kevlar belts from the farm stores are about the worst. A Kevlar wrapped mower deck belt is better. I cannot see anything that is rubbing on the belt. Routing of the belt is correct. Pulleys and idlers seem OK. Tension is good but not excessive. I do not think the belt ever slips. Arbors are greased. Blades are sharp. I can not figure it out. I do know that a farm store belt might be more like $20 and the original Cub Cadet belt might run $45. Is there that great of difference. Has any one else had this issue or any ideas as to what might correct this issue? Thanks.

You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
