Massey Ferguson 275 No PTO or Lift Arms - Multipower Transmission Not Working Also

[Humble Farmer]

We have a 275 and while bush hogging the IPTO quit, lift arms don't work, and the multi power shift will not engage. The transmission still works other than the multi power. The transmission clutch, the PTo pump and clutch were all replaced last season (about 300 hrs ago). I humbly ask where I should look for the problem as I have limited access to a garage to perform work in and don't believe I can do this in a hay barn. Any suggestions to help me limit time in another's garage would be greatly appreciated.

Pressure checks and more than likely some disassembly. Could be malfunction with aux pump, but three PT should still work. Does it have press. control on three point? Are three point levers in correct position? Drain hyd oil, pull off side covers, and look inside to see if something physically came out of place(assembly error).
