OPERATING INFORMATION
HYDRAULIC SYSTEM
The front, larger gear pump (fig. 4.1, item 1) supplies only
the cutter motors or Quad Puller motors. The rear, smaller gear
pump (fig. 4.1, item 2) supplies power steering, the detasseling
head lift cylinders, and the outrigger fold cylinders.
Locate the variable flow control valve that supplies the solu-
tion pump motor with hydraulic fluid (fig. 4.2). Adjust the setting
so no fluid is sent to the solution pump. Remember to open it
back up later when you begin spraying again.
HYDRAULIC SYSTEM CONTINUED
DO NOT GO NEAR LEAKS. High pressure oil easily punctures skin causing injury,
gangrene, or death. If injured, seek emergency medical help. Immediate surgery is
required to remove oil. Do not use finger or skin to check for leaks. Lower load or
relieve hydraulic pressure before loosening fittings.

NOTE:
Full operating speed of detasseling heads
cannot be reached unless the variable flow
control valve to the solution pump is adjusted.
