John Deere 3520 pto clutch problem

[john3520-Rosedale]

So i have 2008 3520 hydrostatic with cab and have been experiencing a problem with the rear pto.
Was using my NH teader rakeand noticed it was slowing down and almost stopping on rough ground.
The rake does not have a clutch so it looks like the pto clutch is slipping.
I have not done any more raking so not sure if this will continue on better level ground.
I also run a snow blower and flail mower on this tractor.
Anyone experience this problem or have to replace pto clutch.
The pto clutch is activated hydraulically via solenoid switch.
I believe you have to split the tractor to access the clutch pack.
Not a good outcome.

Mine is doing the same. When i engage it turns very slowly and finally gets up to speed but when lowering the deck from my mower the shaft slows down and stops . Pto lights are on

That’s bad. I could split the tractor and look at it, stilll would not know what to do
