Forward/reverse shuttling is done with a synchronizer. Seperate the front transmission at the spacer transmission as outlined in Section 1B to access the input gears. PTO Clutch The PTO on is driven thru a wet multi-disced, hydraulically operated clutch pack. For the PTO to work, the mechanical PTO lever located at the rear 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 Clutch Packs Oil is transfered from the auxillary (steering) 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 maintains line pressure to the secondary circuit to operate the PTO clutch pack.
