(1) Implement lockout switch. (2) Lift control lever. (3) Tilt control lever. (4) Auxiliary control lever.Lift control lever (2), tilt control lever (3), and auxiliary control lever (4) are controlled manually by the operator. The control levers send electronic signals through the implement control to the solenoids on the pilot valve. The pilot valve sends a low pressure signal to the main control valve. This signal causes a valve spool in the main control valve to send high pressure oil to the implement cylinders. The cylinder rods will extend or the cylinder rods will retract.The optional auxiliary implement system has an auxiliary pilot valve, an auxiliary control valve, and auxiliary cylinders. To control the auxiliary implement system, third control lever (4) is added in the operator station.Implement lockout switch (1) is used to disable the implement pilot system. When the switch is in the LOCKED position, the pilot supply on/off solenoid is off. No pilot pressure is allowed into the pilot valve. When the switch is in the UNLOCKED position, the pilot supply on/off solenoid is on. Pilot pressure is allowed into the pilot valve.
