MF 1085 three point problem

M SLABA · Aug 18, 2014

I have a 1085 that the three point hitch will not lift on. It will raise with no weight on it, but just me standing on the arm will stop it. I checked the pressure at the test port on the top cover and have less than 100 psi. when idling and just at 100 throttled up. Is the pump bad or is there a relief valve or another valve that could be the problem? Any input would be appreciated.

I don't have any experience on the 1085 specifically but if it started suddenly I'd be more inclined to think it's an o-ring seal or pressure relief valve.

If it has an aux hydraulic line with diverter valve under the seat, I was able to eliminate the pump as being the problem by checking the pressure on the aux line.
I didn't have but 100psi as a straight test because an o-ring was loosing all the pressure but when I switched it to a different circuit (by passing that o-ring) to the aux line I had good pump pressure.

Again, yours may be different as mine is a 165 and doesn't have a separate aux pump.

make sure that the linkages aren"t loose
