Deck Leveling & Height Adjustments
There are 4 primary adjustments that should be made
prior to actual field operations:
•
Deck Leveling From Left to Right
•
Deck Leveling From Front to Rear
•
Center 3-Point Link Adjustment
•
Tailwheel Height 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
•
Carpenters level
•
3/4" Open end or hex end wrench or socket set
•
Protective gloves

WARNING
To avoid serious injury or death:
Always shut tractor down using "Tractor Shutdown
Procedure" provided in this manual before dismounting
tractor.
Deck Leveling From Left to Right
Refer to Figure 2-1:
1. Locate tractor and Rotary Cutter on a flat, level
surface.
2. Use tractor's hydraulic 3-point control to lower cutter
until tailwheel contacts ground surface.
3. Place a Carpenters level or other suitable leveling
device on the front of the cutter deck. Adjust either one
or both of the tractors 3-point lower link height
adjustments to level the deck from left to right. Some
tractors have only a single adjusting crank.
Deck Leveling From Front to Rear
!
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
cause injuries.
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.
Refer to Figure 2-1:
Place a Carpenters level on one of the main deck

channels. Using the tractor's 3-point hydraulic control
lever, raise or lower the 3-point arms until the deck is
slightly lower at the front (approximately 1" lower)
than at the back.

3. With gloves on, carefully rotate each blade to the
position shown in Figure 2-5 on page 19.
4. At the front of the cutter , measure the distance from
blade cutting tip to ground surface. This distance is
known as the "Nominal Cutting Height".
5. The tail wheel will need adjusting if nominal cutting
height is not at the preferred cutting height. Adjust
tailwheel per instructions on page 19.
6. Repeat steps 1 to 5 until preferred cutting height is
achieved.

2. Typically the center 3-point link is adjusted so that the
upper 3-point clevis pin is straight above the lower 3-
point hitch pins. This arrangement allows for
optimum ground contour following performance.
