KEY PART DESCRIPTION
1 A125162-02 PUSHOFF SEQUENCE CARTRIDGE
2 A125162-01 COUNTER BALANCE CARTRIDGE
SETTING THE APRON AND PUSHOFF VALVE
The manifold block containing the pushoff sequence valve cartridge and apron sequence valve
cartridge is used to control two hydraulic circuits with one hydraulic remote. When the tractor hydraulic
remote is activated, oil flows first to the apron cylinders until they are fully extended. Once the cylinders
are fully extended, the apron circuits’ hydraulic pressure begins to increase. Once the pressure threshold
is surpassed (which is adjustable. See adjustment section), the sequence valve diverts the oil flow to the
pushoff’s hydraulic circuit. Once the push off is completely extended the operator then reverses the
tractors hydraulic remote. The counterbalance valve will hold the apron open until the push off is fully
retracted. The Apron sequence valve then opens and allows the apron to close.
Setting the valves:
STEP 1 PUSHOFF SEQUENCE VALVE
Loosen the lock nut (9/16”) on the sequence valve cartridge. Turn the setscrew (4mm) clockwise
until the front apron rises before the push-off begins to advance. (Earthmover should be empty) Turn
the adjustment screw an additional 1/4 turn clockwise and tighten jam nut.
STEP 2 COUNTER BALANCE VALVE
Loosen the lock nut (9/16”) on the counterbalance valve cartridge. Turn the setscrew (4mm)
counter-clockwise until the apron holds in a raised position while rear gate is being retracted. Turn
adjustment screw an additional 1/4 turn, tighten jam nut. DO NOT tighten adjusting screw more than
necessary.
