I'm not sure how long the PTO was operated with a jammed blade (seconds?, minutes?) but the drive pulley does look a bit overheated on the outside (rust seems darker than in the old topic's photo) but the inside isn't discoloured and seems fine. I'm not sure of the hours on the belt but it's been on for several seasons and there are some worn spots on the bottom of the vee. It doesn't look like there are any burned spots on the belt. There also don't appear to be any burned spots on the mower belt. My guess is that the clutch slipped rather than the belts.
I have a some questions:
- Can this clutch withstand slippage for (say) one minute?
- Is there a rebuild kit for this clutch?
- If I need to replace the clutch, what would be my best option?
