    What to do if it is not possible to place KUHN GMD602 GII in "headland turn" position?
    • D
      Dawn FaulknerAug 5, 2025
      If you cannot place your KUHN Farm Equipment in the "headland turn" position, it might be because the hydraulic circuit was not pressurized correctly. To resolve this, connect the 2 hydraulic hoses of the transport/work position cylinder to a double acting valve with float position. Open the hydraulic valve using the 18mm box spanner supplied with the machine. Shift the tractor hydraulic valve in the direction for placing the machine in working position, to pressurize the circuit to 93 bar (1348 psi). Shut off the hydraulic valve. Shift the tractor's hydraulic valve in float position. The pressure on the gauge drops. Repeat these operations several times until the pressure stays at 93 bar (1348 psi).
