Tie or block the clutch pedal down. In 3rd gear. Roll the tractor forward or backward. If the clutch is working the drive shaft and engine will not turn. If the drive shaft and engine turn with the clutch depressed - problem is within the clutch system - some place.outdoors4evr wrote:You can test this out while the covers are off the tractor and the engine is off. (Use a rope or a tiedown to hold the clutch pedal while testing) Put the tractor in third (road gear).
Leave the clutch brake disconnected - as shown in your last photo.
