Leveling & Cutting Height
Adjustments For 3-Point & Semi-
Mount Cutters With Rear Axles
The following instructions are for leveling and cutting
height adjustments for 3-Point and Semi-Mount cutters
with rear axles. See page 31 for “3-Point Cutters With
Beam Arms” and page 35 for “Pull-Type Cutters With
Rear Axles”.
Three primary adjustments should be made prior to actual
field operations:
• Deck Leveling Left To Right
• Cutting Height Adjustment
• Deck Leveling Front To Back
Proper adjustment of each of these items will provide
higher efficiency, improved cutting performance and
longer blade life.
!
WARNING
Always disengage PTO, put tractor in park or set park brake,
shut tractor engine off, remove ignition key, and wait for all
moving parts to stop before dismounting from tractor.
Deck Leveling Left To Right
This adjustment should be made with cutter hooked to the
tractor that will be used for field operations
1. Having completed “Tractor Hook-up”, locate tractor
and cutter on a flat, level surface.
2. Use tractor’s hydraulic 3-point control to lower the
cutter until the front of the skid shoes are 2 to 3 inches
off the ground.
Refer to Figure 3-5:
3. Place a spirit level or other suitable leveling device
across the front of the deck.
4. Adjust either one or both of the tractor’s lower lift arms
up or down to level the deck from left to right. Some
tractors have only a single adjusting crank.

CAUTION
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
cause injuries.
1. With gloves on, carefully rotate blade tips on one side
of the cutter to the position shown in Figure 3-6.
2. Measure distance from end of blade (cutting tip) to
ground. This distance is the cutting height.
3. Using tractor’s 3-point hydraulic control lever, raise or
lower the 3-point arms until the front blade tip is at the
desired cutting height.
4. Set tractor’s 3-point hydraulic control stop once the
tailwheel and 3-point arms are properly adjusted.

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
front blade causing horsepower loss, grass clumps,
blade wear, and frequent blade sharpening.
