V. OPERATING INFORMATION

HYDRAULIC SYSTEM CONTINUED Detasseling Heads

The hydraulic motors on the detasseling heads (fig. 5.23) are turned on and off with a row of switches mounted on the control panel to the right of the operator’s seat (fig. 5.22). To open the solenoid on any of the motor control valves (fig. 5.21) which activate the motors, flip the corresponding switch(es) away from the operator’s seat. To shut any or all motors off, flip the corresponding switch(es) toward the operator.

Each motor control valve contains a .182 inch orifice disc that restricts hydraulic flow to th e hydraulic motors so they don’t overspeed and become damaged.

Activate hydraulic motors while engine speed is at an idle, then increase engine RPM to operating speed.

Caution

Before Engaging Hydraulic Motors

1. REDUCE ENGINE SPEED TO AN IDLE

2. CLEAR AREA OF UNAUTHORIZED PERSONNEL

DO NOT operate the hydraulic motors on detasseling heads without .182 inch orifices in place under each solenoid coil.
