3-Point Hitch Mahindra 7520 4wd with 275 loader / lift arms don't work

Dealer replace engine under warranty. Since replacement the rear 3pt lift arms has not worked. Oil and filters has been changed. All remotes been checked at 2600 psi. Lift arm levers are not stuck. Dealers said there is no oil flow charts so I can see if I can chase the problem that way. Been four yrs since lift arms has worked.

It was the dealers problem. Too late now I guess.

Dealer didn't have anybody that knew anything about Hyd They took 8 months to change engine.

8 months to R&R an engine ! flat rate without looking i'd guess is only 20hr 0r so. I looked at the JIC schematic for you tractor. its in the work shop man. That dealer was blowing smoke up you 6. 3pt lift valve is at end of line. Check you draft control feed back linkage adj. Do you have a FEL on this unit?:confused3:

I'm guessing that the lift is all the way up and won't go down. Is this correct?

If so, push the 3pt control lever all the way forward, then open the valve (under your seat just above the floor) a few turns and see if it goes down.

If I'm wrong....never mind.

The 7520 does not have a manual valve to limit down speed. It automatically senses weight and adjusts to prevent a quick fall of a heavy implement.
,,, OP has not given sufficient info to make any educated guess as to the nature of the problem.
