I have a 4450 with the 15 speed powershift that the hydraulics have quit on. Everything was running fine, stopped the tractor to fuel up, used the loader to lift the front wheel to check the hub oil levels and left the wheels up when I turned the tractor off.
Upon restarting there were no hydraulics of any kind. No remotes, the tractor would not move and the steering had no power. The second time it was started the tractor would drive and the steering returned but still no remotes. I used this opportunity to get the tractor the 100 feet to the shop and turned it off. Now when the tractor is started there are no hydraulics again. Hydraulic oil is at the correct level, clean, and no smells. Hydraulic filters were all changed approximately 30 hours ago because it was time to change them. There are 5500ish hours on the tractor.
Does anyone have any ideas on what might be wrong with this thing? Thanks in advance.
