Detasseling Heads
The hydraulic motors on the detasseling heads (fig. 4.13)
are turned on and off with a row of switches mounted on the
control box to the right of the operator’s seat (fig. 4.12). To
open the solenoid on any of the motor control valves (fig. 4.11)
which activate the motors, flip the corresponding switch(es) up.
To shut any or all motors off, flip the corresponding switch(es)
down.
Each motor control valve contains a .182 inch orifice disc
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.
DO NOT operate the hydraulic
motors on detasseling heads
without .182 inch orifices in place
under each solenoid coil.
