Field Operation
You may be severely injured or killed by being crushed between
the tractor and hitch. Do not stand or place any part of your
body between hitch and moving tractor. Stop tractor engine and
set park brake before installing the hitch pin.
Escaping fluid under pressure can have sufficient force to pene-
trate the skin. Check all hydraulic lines and hoses before apply-
ing pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
1. Hook hitch to a suitable tractor and drill. Refer to
Hooking Hitch to Tractor and Hooking Hitch to Drill,
“Preparation and Setup,” page 8.

ure 2-1.
