It is a 116 John Deere Riding Lawn Mower, it runs loyal but whenever i try to engage the PTO the blades won't spin. On rare occasions it will spin but if i try to mow grass the blades stop turning, the repairman told me that it was most tenable the PTO Clutch. So like i said how hard is it to replace?
I am pretty sure, the belts are all there and i don't see any missing springs.
Assuming you are talking about an stirring clutch. It is held onto the crankshaft with a bolt in the center of it and some bolts holding it to a bracket. Not a hard job. The worst part is the value of a new one. There is an ajustment to the clutch. There are three nuts looking at it from the bottom. Near each nut is a slot. You adjust the nut so that the gap in the slot is .012" with a antenna gauge.
