I recently purchased an older model 1800 Tractor. When it is cold, the hydro. lift works great. After a few minutes it quits working altogether. Help??

I'd change all fluids and filters and clean any screens on a used tractor on general principal unless the maintenance history is well known. That might cure the lift problem. If not I'd start by inspecting the suction line for breaks or leaks and also see if the hydraulic oil gets hot and frothy. If there's a sound like a rattle or buzzing from the hydraulic pump or the oil gets very hot I wouldn't run the tractor very long. ....

Hey Tom:
Yes, the fluid gets a lot of air bubbles in it, but it doesn't get very hot.

Sounds to me that if the fluid is aerated and not hot, the pump is probably shot. Most likley the pump housing expands just enough to allow hydraulic fuid to pass by the sides of the pump gears. When it does that, it cavitates.
When I'm working my backhoe too much or too hard I would have to run cool water over the pump, reservoir and the oil cooler to get it to cool down enough to use it again. You might have a clogged oil cooler too, but most likely it's a worn out pump---in my opinion. ....
