Hi everyone, i have a John Deere 400D 2007 SN DW400DT613136, the brakes aren't working and the dumper doesn't go up, our mechanics think it could be the hydraulic oil manifold, the flow Control Hyd. valve or the double pump that actuate the brakes and dumper. Anyone of you had any issue like this? that could help me solve this out. Thank you!
If you don't already have it, I highly recommend acquiring the Operation and Test Manual TM1198. Have pressures been checked?
