(8) Solenoid (9) Passage to Hydraulic Tank (10) Passage from Pressure Reducing Valve (11) Pilot SupplyImplement lockout valve (1) is located in the pilot manifold.When the machine is on, solenoid (8) is energized. Pilot oil from pressure reducing valve (4) enters the valve through passage (10). The valve directs the pilot oil to passage (11). Pilot supply now flows into the inlet manifold. The inlet manifold distributes the pilot supply oil to either end of each implement control valve and to either end of the dual tilt valve (if equipped).If the operator activates the implement lockout switch in the cab, solenoid (8) is de-energized. Implement lockout valve (1) closes. Pilot oil from pressure reducing valve (4) is blocked and the implements cannot be operated. Pilot supply from the implement control valves and from the dual tilt valve (if equipped) returns to the hydraulic tank through passage (9).
