The pilot system controls the functions of the main control valve. The pilot hydraulic system is controlled by the implement electronic control system.The main hydraulic system consists of implement pump (9), implement control valve (6), and the implement cylinders.Implement pump (9) is a piston type pump. Implement pump (9) is installed on the transfer gear case housing. The pump supplies oil to implement control valve (6).The Implement hydraulic system is controlled by the implement ECM (13). The ECM responds to operator control inputs. When the operator commands hydraulic attachments to move, the ECM activates the appropriate pilot solenoid valves. The valves allow oil to flow to the corresponding main control valves. The main control valves control the various cylinders and hydraulic attachments. The operator joystick has detents that are activated by the ECM.
