Deck Leveling & Cutting Height
There are 4 primary adjustments that should be made
prior to actual field operation:
•
Deck Leveling From Left to Right
•
•
Center 3-Point Link Adjustment
•
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance, and
longer blade life. The following tools will be needed:
•
Pliable tape measure
•
Spirit or carpenters level
•
Set of wrenches and/or socket wrench set
•
Protective gloves
WARNING
!
To avoid serious injury or death:
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
Deck Leveling From Left to Right
Refer to Figure 3-2 on page 21:
1. Locate tractor with Rotary Cutter on a flat, level
surface.
2. Use tractor’s hydraulic 3-Point control lever to lower
cutter until tailwheel makes contact with ground
surface.
3. Place a level on the cutter deck as shown. Manually
adjust one or both lower 3-Point lift arms until deck is
level from left to right. On some tractors, only one arm
can be adjusted vertically.

WARNING
!
To avoid serious injury or death:
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
1. With gloves on hands, carefully rotate each blade tip
to the position shown in Figure 3-1.
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 the 3-Point arms until the front blade tip is at
the desired cutting height.
4. The top center link should be loose when deck rear is
supported by the tailwheel. If not, lengthen 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 the front blade or is more
than 1" higher than the front blade, then the tailwheel
height must be adjusted. If needed, see
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.
IMPORTANT:
The front blade tip should be lower
than rear blade tip by approximately 1". The cutter is
subject to continuous material flow under the deck if
the rear blade is at the same height or lower than the
