5. REMOTE CONTROL VALVE (IF EQUIPPED) Neutral Pressure-fed oil from the hydraulic pump is delivered into the P port, and flows to the rear hydraulic outlet through BY port. At this time, oil from A port to the T port is blocked by the mechanical check valve (Poppet (1)). Therefore the position of implement is kept at the set position. (1) Poppet (2) Piston (3) Spool

Lift When the remote control valve operating lever is set to LIFT position, the spool (3) moves to the right and the passage from P port to the BY port is blocked by the spool (3). Then the pressure-fed oil open the poppet (1) and flow through the A port to the hydraulic cylinder to lift the implement. (1) Poppet (2) Piston (3) Spool

Down When the remote control valve operating lever is set to DOWN position, the spool (3) moves to the left and the passage from P port to the BY port is blocked by the spool (3). At the same time, the piston (2) and poppet (1) moves upward, and open the passage from A port to T port. Then the pressure-fed oil flow through the B port to the hydraulic cylinder to lower the implement. Return oil from hydraulic cylinder flows from A port to the transmission case.
