A couple weeks ago I bought my Grandpa's 2020 from my Grandma. It had been parked in the machine shed for 15+ years because the hydraulics quit working on it again for the second time and Grandma wasn't going to spend the money to fix them again. I am pretty sure it isn't the high pressure pump since when I first got it started the lift arms worked right and steering was fine. After it ran for a few minutes the lift arms became "chattery" when lifting and the clutch wont completely disengage. Steering and brakes seem to work fine though.
I am going to change the filter and check the screen but my uncle who was running the tractor when it started acting up and parked said that he had just changed the filter and checked the fluid right before it quit years ago.
From looking at the service manual and pics of the pump online it looks to be a standard gear pump. The tractor only has 3400 hours total on it and it was taken care of. I may be wrong but the pump should last much longer than that. If in fact it is the transmission pump is this something I can tackle myself or would I have to split the tractor? The picture in the FSM isn't real clear but I am thinking it is on the back of the clutch housing.
If anyone has any suggestions I would appreciate it. I am going to run by Deere tomorrow and get some hydraulic fluid and a new filter and will check the screen for blockage.
