820 PTO problem

My pto did the same thing. It turned out that the clutches were worn out and the brake plate lining was gone. The seal between the pto and rear end had let gear oil into the pto housing. That ruins the pto clutches. It's also a big pain to get to. Look in the book for details.

I spent about $350 on clutch discs. Many of the clutch plates were scored and had to be replaced. The good news is that you can still get the parts from your JD dealer.

The hardest part is replacing the pto housing and clutch assembly. If you don't have the clutch assembly perfectly aligned, it won't go into the clutch drum. And the pto assembly is HEAVY!

Good luck.

I'm not an 820 guy, but I did stay in a Holiday Inn Express last night !

Seriously, what I would do first is to disconnect the linkage at the PTO box down below. Then I'd use a wrench on that clutch fork shaft to engage the pto clutch manually. Then I'd see how far you would have to re-adjust that link to make that position be right, because if you don't readjust the clutch, that's where it will have to be to function without slipping or holding the lever forward.

If that position is dramatically different from where you have it now with the brake functioning properly, then I'd think next you'll need to look into a worn out brake facing or clutch pack.

But I'm just-a guessin' !
