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 FIG 5.21
that restricts hydraulic flow to the 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 FIG 5.22
