3-Point Leveling & Cutting Height
There are four primary adjustments that should be made
prior to actual field operation:
1.
2.
3.
Single & Dual Tailwheel Adjustment
4.
Center 3-Point Link Adjustment
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance, and
longer blade life. Pliable tape measure, spirit or
carpenters level, set of wrenches, and protective gloves
will be needed.
WARNING

3.
Place a level on the cutter deck as shown. Manually
adjust one or both lower 3-Point lift arms vertically
until deck is level from left to right. On some tractors,
only one arm can be adjusted.
Cutting Height Adjustment
Refer to Figure 2-2:
WARNING
!
To avoid serious injury or death:
1.
With gloves on, carefully rotate blades and stump
jumper until blade tips are in the position shown.
2.
Measure distance from cutting tip of front blade to
ground surface. This distance is the cutting height.
3.
Using tractor’s 3-Point hydraulic control, raise or
lower 3-Point lift arms until the front blade tip is at the
desired cutting height.
4.
The 3-Point center link should be loose when deck
rear is supported by the tailwheel. If not, lengthen 3-
Point center link until loose. Final adjustment will be
made later.
5.
Measure distance from cutting tip of rear blade to
ground. This distance should be slightly higher than
the front blade but not more than 1" higher.
6.
If rear blade is lower than front blade or more than 1"
higher than the front blade, then tailwheel height
must be adjusted. If needed, see
instructions on page 27.
7.
Repeat steps 1 through 6 until tailwheel and 3-Point
arms are adjusted to the desired cutting height.
8.
Set tractor’s 3-Point hydraulic control stop once the
tailwheel and 3-Point arms are adjusted properly.
