HYDRAULIC SYSTEMS

Dump Valve

The Dump Valve (located beneath the

operator’s seat) is the main valve, which
controls the amount of pressure going to the
lift valve.

NOTE: The Dump Valve is factory pre-set to

2200 psi (151.7 bar).

NOTE: To check Dump Valve psi/bar, install

a 3000 psi (206.8 bar) pressure
gauge on the Dump Valve Inlet. If

additional adjustment is required,
contact your John Deere dealer for
assistance.

Detasseling Heads

The hydraulic motors on the detasseling

heads are controlled by the Master
Detasseler Switch and are individually turned
on/off using the Detasseling Head Motor
Control Switches (located on the side
console).

Motor Control Valves

•

To open the solenoid on the Motor Con-
trol Valve(s) (which activate the motors),
press the corresponding Detasseling
Head Motor Control Switch(es) (located
on the side console) in the ON (Up) posi-
tion.

•

Press Detasseling Head Motor Control
Switch(es) in the OFF (Down) position to
turn motors off.

NOTE: Activate hydraulic motors while

engine speed is at idle, then increase
engine RPM to operating speed.
