For the PTO to work, the mechanical PTO lever on the LH side of the tractor must be engaged and the on/off switch on the console must be in the "ON" position. When the switch is in the "ON" position, the PTO valve is energized allowing oil pressure to clamp the discs in the PTO clutch pack together and turn the PTO shaft. Oil Supply to PTO Clutch Pack Oil is transfered from the main hydraulic pump to a reducing valve. The reducing valve acts as a flow divider, dividing the flow of oil to a primary and secondary circuit. Oil for the PTO clutch pack is supplied by the secondary circuit of the reducing valve. The reducing valve also maintains line pressure to the secondary circuit to operate the PTO clutch pack. Refer to the HYDRAULIC section for more information on the reducing valve. FIG. 5A-11: Oil pressure to the PTO clutch pack can be checked using an adaptor fitting from tool kit ATP3031 and a pressure gauge. The test port for the PTO clutch, 1, is located on the LH side of the tractor below the PTO solenoid valve.
