THREE-POINT HITCH
Three-point hitch combines Tractor and implement
into one working unit. Implement position and raising
are controlled hydraulically. In addition, implement
weight and loads impose downward pressure at Trac-
tor rear wheels to increase traction.
Hitch Controls
FIG. 5-31:
Control quadrant, to right of operator’s
seat, controls the system to provide the following hitch
control functions:
Position Control -
Maintains hitch position at con-
stant height in relation to the Tractor. As position con-
trol lever, 1, is moved rearward, hitch (and implement)
are raised. Moving lever forward will lower hitch to se-
lected position. Each lever setting provides a specific
hitch (and implement) position.
Draft Control -
Regulates hitch height to provide
constant draft or “pull” of ground engaging implements
(plows, subsoilers, etc.). Moving draft control lever, 2,
forward will provide deeper implements working depth.
Moving lever backward will provide a shallower depth.
As ground contours and / or soil conditions change,
the system will raise or lower implements as needed
to keep even load in Tractor.
CAUTION: Use position control lever, 1,
when attaching or detaching implements.
Place draft control lever, 2, fully forward
when using position control.
FIG. 5-32: Lowering Rate Control -
Knob, 3, controls
discharge rate of hydraulic oil to adjust lowering speed
of hitch and implement. Turn knob clockwise to slow
drop rate, counterclockwise to increase drop rate.
Turning knob fully clockwise will lock implement in
raised position.
CAUTION: When working on or around
mounted implements, always lower to
ground prior to work. If implement must
be raised, always block implement and
lower links securely.
