DETERMINING 3-POINT HITCH MODE OF
OPERATION
Position/Float Control Test
If the implement is equipped with gauge wheels or
some other depth control device, the use of float
position is needed. To determine if position or float
control is needed for an application without gauge
wheels or other depth control device, perform the
following test.
1. Attach and adjust the implement as described in
the implement operator’s manual.
2. Turn the position/draft sensitivity control knob, 1,
to position control (counterclockwise).

3. Set the lower link lock plate into the float position,
3, (vertical).
4. During normal field operation, lower the 3-point
hitch to the full down position engaging the
implement fully into the ground. Pull the
implement until it reaches its operating depth,
stopping the tractor with the implement still in the
ground.

5. Check the position of the lower link lock plate and
pin.
-- If the lower link lock plate and pin are at the
top of the float slot, float position is needed.
-- If the lower link lock plate and pin are at the
bottom of the float slot or the implement
drops to a depth causing the tractor to loose
traction, position or draft control is needed.
