POSITION/DRAFT SENSITIVITY
CONTROL KNOB
(ELECTRONIC DRAFT CONTROL ONLY)
The position/draft sensitivity knob, 1, (if equipped), is
used to select position control or draft control. A decal
encircling the knob has six numbered positions, to
indicate the degree of response selected. Turn the
position/draft sensitivity knob towards the full position
control setting (position 1) to decrease the system’s
response to a change in draft loading. The knob is
detented at the position control setting (position 1 – knob
fully counterclockwise).
IMPORTANT: Always set the position/draft sensitiv-
ity knob to the full position control setting (position 1)
at any time when not actually operating in draft
control, such as when attaching equipment,
transporting equipment or when no equipment is
attached.
If precise depth control is required, the position/draft
sensitivity knob must be in the full position control
setting.
Whenever the draft control feature is selected, the
implement operating depth will automatically vary as
required to maintain a fixed load, as determined by the
lift control lever, on the tractor engine.
IMPORTANT: Draft control will work with a variety of
draft implements, however, hitch response to low
draft/shallow implements will be difficult to obtain if
sufficient draft load is not detected on the load sense
pins. Using draft control with implements that do not
create a sufficient draft load will result in the implement
going to a lower position seeking more draft. See
DETERMINING 3-POINT HITCH MODE OF OPERA-
TION in this section to verify if draft control operation is
suited for your implement.

DROP RATE CONTROL KNOB
The drop rate control knob, 2, controls the speed at
which the lower links and implement drop during a
lowering cycle. This knob has a decal encircling it
with six numbered positions. Position 1 is the slowest
rate and is denoted by a “tortoise” symbol. Position
6 is the fastest setting, denoted by a “hare” symbol.
HEIGHT LIMIT CONTROL KNOB
The height limit control knob, 3, limits the height that
the linkage may be raised. Adjust this knob to avoid
the possibility of a large implement damaging the
tractor cab when fully raised.
Turning the knob fully counterclockwise prevents the
3-point hitch from raising above mid height. Turning
the knob fully clockwise will allow the 3-point hitch to
raise to full height.
