Level & Set Deck Height (Pull-Type)
The following instructions are for leveling the
Pull-Type cutter. See page 27 for
“Level & Set Deck
Height (3-point)” instructions.
There are two primary adjustments that should be made
prior to actual field operation:
•
“Level Front To Back (Pull-Type)” on page 29
•
“Cutting Height (Pull-Type)” on page 29
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
!
To avoid serious injury or death:
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
tractor.
Level Front To Back (Pull-Type)
This adjustment should be made with cutter hooked to
the tractor that will be used for field operations or to one
having the same drawbar height and length. Adjust
leveling rods as described below.
Refer to Figure 3-6:
1. Attach cutter to the tractor that will be pulling the
cutter and position tractor and cutter on level ground.
2. With gloves on, carefully rotate blades and stump
jumper until blade tips are in the position shown.
3. Using tractor control lever, adjust deck height so that
the front blade tip is 3 to 4 inches above ground.
NOTE: The tip of the front blade should be lower than
the tip of the rear blade. If front and rear blades are at
the same height or if rear blade is lower than the front
blade, then the cutter is subject to continuous material
flow under the deck resulting in loss of horsepower,
additional blade wear, and frequent blade sharpening.
Refer to Figure 3-8:
4. Measure distances the front blade and rear blade tips
are off the ground. The deck is properly leveled when
rear blade tip is slightly higher than front blade tip but
not by more than 1".
If rear blade tip is too low:
a. Loosen jam nut (#2) several turns.
b. Unscrew hex coupler nut (#3) clockwise (direction
shown by arrow) to raise cutter rear.
c. Re-tighten jam nut (#2) against coupler nut (#3)
when height of rear blade tip is acceptable.
If rear blade tip is too high:
a. Loosen jam nut (#2) several turns or more.
b. Tighten hex coupler nut (#3) counterclockwise
(opposite direction shown by arrow) to lower cutter
rear until height of rear blade tip is acceptable.
c. Re-tighten jam nut (#2) against coupler nut (#3).

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.
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
tractor.
NOTE: Lengthen leveling rod (#1) to raise cutter
rear and shorten leveling rod to lower cutter rear.
