SECTION 2 - OPERATION
2-91
FIELD OPERATION
After attaching an implement to the three-point hitch,
adjust the height limit control knob, 2, to prevent large
implements from damaging the tractor cab, and
adjust the drop rate control knob, 3, to set the desired
rate at which the implement will drop when the hitch
is lowered.
To set the height limit control, proceed as follows:
• Turn the height limit control knob, 2, fully
counterclockwise which will allow the hitch to
raise to one-half its full height.
• Pull the lift lever, 1, fully to the rear.
• Slowly turn the height limit control knob, 2,
clockwise to raise the implement until no less
than 100 mm (4″) clearance is remaining
between the tractor and implement or maximum
hitch is reached.
Adjust the rate or implement drop by rotating the drop
rate knob, 3. Turn the knob clockwise to speed up the
drop rate or counterclockwise to slow down the drop
rate.
IMPORTANT: When first setting the implement up for
work, keep the drop rate control knob in the slow drop
position (“tortoise” symbol).
NOTE: The drop rate control only affects the lower
link/implement drop rate when the implement is not
engaging the ground.
POSITION CONTROL OPERATION
NOTE: See DETERMINING 3-POINT HITCH MODE
OF OPERATION in this section for procedures to
verify if position control operation is needed for the
implement being used.
To operate in position control:
1. Turn the position/draft sensitivity control knob, 4,
fully counterclockwise (position 1) into the
detented position.
NOTE: Failure to turn the position/draft sensitivity
knob into the detented position will cause the hitch to
make automatic hitch corrections as it searches for
a draft load.
2. Use the 3-point hitch lift control lever, 1, to control
movement of the hitch. Pull the lever rearward to
raise the 3-point hitch and push the lever forward
to lower the hitch. The EIC hitch position display,
2, Figure 128, will show the current hitch position.
