Combines Hydraulic speed

Just went through that kinda thing with my TR86. Had a pump leaking through a pin hole in the housing so I got a used pump from a neighbors burnt machine and used it for about 100 acres then it did what yours is doing. So I swapped pumps from our TR95 onto it and it did the same thing. Thought it was the TR86 itself but it ended up being two bad pumps, dad uses the TR95 and is kinda ignorant to the small things so he never noticed the weak hydraulic pump. Got one rebuilt pump and one new updated pump. All is good now! I would say it is your pump. Almost cheaper to just replace it than it is to have it checked out then and have to replace it anyways.

I wouldn't be sure it's the pump. Why would everything else work goodIJ Why would your feederhouse not go down at high idleIJ Sounds like a valve problem to me. Mine was doing strange stuff like that. Found there was an o ring missing around a seat in the lift valve. Took awhile to find the problem. Good luck.
