MF25 hydraulic three point lift problem

[tom cunning]

I have a MF25 tractor the three point lift works fine after i start the tractor. Then it warms up and gets sluggish then finally just stops working. Any suggestions?

Sounds like a bad seal on the 3 point piston. Oil warms up and thins and starts leaking past the seal. Do you have any other hydraulics. You can go to AGCO Parts Books ( enter as guest) to see parts diagrams of your tractor.
