Information:

The hydrostatic system is a closed loop. The hydrostatic system is made up of the following main components: Hydraulic Tank Group (1), Gear Pump (charge oil, implement, air conditioner and fan drive) (2), Piston Pump (hydrostatic system) (4), Piston Motor Group (hydrostatic right side) (5) and Piston Motor Group (hydrostatic left side) (21) .The oil that flows from the Piston Pump (hydrostatic system) to the Piston Motor Groups (hydrostatic system) flows in a continuous loop. The oil then returns to the Piston Pump (hydrostatic system). The hydrostatic system is kept full of oil by the charge system. The forward section of the Gear Pump (charge oil, implement, air conditioner and fan drive) supplies both sections of the Piston Pump (hydrostatic system) with charge oil.

Hydrostatic System Components (1) Hydraulic Tank Group (2) Gear Pump (charge oil, implement, air conditioner and fan drive) (4) Piston Pump (hydrostatic system) (5) Piston Motor Group (hydrostatic right side) (21) Piston Motor Group (hydrostatic left side)Pilot oil flows from the Pilot Valve (hydrostatic system) (16) to the pilot pressure ports (7), (8), (18), and (22) that are on the Piston Pump (hydrostatic system). The pilot oil causes the pump actuator groups (6) and (19) in the Piston Pump (hydrostatic system) to move the swashplates. This causes the Piston Pump (hydrostatic system) to pump oil to the Piston Motor Groups (5) and (21) .When the Piston Pump (hydrostatic system) is in the NEUTRAL position only charge pressure will flow out of "A" loop port (9) and "B" loop port (10) .In the NEUTRAL position, no high pressure oil flow is provided to the piston motors. The hydrostatic system oil pressure will be equal to the charge oil pressure. If the travel control lever is pushed to the FORWARD position, the Pilot Valve (hydrostatic system) (16) opens a path for the oil to flow to the pump actuator group (hydrostatic right side) (6) and the pump actuator group (hydrostatic left side) (19). The oil that flows into the "X 4" pilot pressure port (hydrostatic right side) (8) causes the actuator piston (6) to shift upward. The pilot oil also flows into the "X 4" pilot pressure port (hydrostatic left side) (18). The pilot oil that flows into the "X 4" pilot pressure port (hydrostatic left side) (18) causes the actuator piston (19) to shift downward. The movement of the actuators causes the swashplates to move. Movement of the swashplate will cause piston pump (4) to upstroke. The flow of the oil out of the "B" ports (10) and (15) that are in the Piston Pump (hydrostatic system) (4) increases. Refer to the Systems Operation, "Pilot Hydraulic System" for additional information about the pilot valve. Refer to Systems Operation, "Piston Pump (Hydrostatic System)" for additional information about the piston pump.The oil that flows out of "B" ports (10) and (15) causes Piston Motor Groups (5) and (21) to rotate. The shafts of the Piston Motor Groups
