Level Center Deck
1.
With cutter attached to a tractor, disengage power
take-off, and park on a level, hard surface. Place
tractor gear selector in park or set park brake.
2. Using hydraulic lift, adjust center deck height so that
front skids (#2) are 2 to 3 inches above ground.
3. Wait for blades to come to a complete stop and then
fold wings up to transport position.

4. Shut tractor engine off and remove switch key before
dismounting from tractor.
5. Lock wings in the up position with transport pins. See
on page 32 for instructions.
6. On both sides of the center deck are continuous
hinges (#1). Measure distance from bottom of hinges
to ground at the front and back. They should be equal
distance off the ground at the back and 1" closer to
the ground at the front than they are at the back.
If continuous hinges are too high at the front:
a. Loosen jam nuts (#3).
b. Loosen coupler nuts (#4) an equal amount to
lengthen both leveling rods until hinges (#1) are 1"
lower in the front than in the back.

IMPORTANT:
nuts (#4) will lengthen leveling rods and lower front
of cutter. Tightening coupler nuts (#4) will shorten
leveling rods and raise front of cutter.
NOTE:
1" measurement can be lowered or raised
depending on cutting conditions.
If continuous hinges are too low at the front:
a. Loosen jam nuts (#3) several turns.
b. Tighten coupler nuts (#4) an equal amount to
shorten both leveling rods until hinges (#1) are 1"
lower in the front than in the back.
7.
Be sure both sides are equal distance from ground to
continuous hinges and that left and right leveling rods
have equal tension. Re-tighten jam nuts (#3).

Level Wing Decks
Each wing section will need adjusting if wing top is not
level with center deck top when wings are unfolded.
1.
Start tractor and, lower wings down. Refer to
on page 33 for instructions on how to lower
wings.
2. Pull cutter straight forward six to ten feet to allow
outer wing wheels to properly align themselves.
3. Check wing tops with a level to see if they are level
with the top of the center deck. If the outer edge of
either wing top is higher or lower than the center
deck, then that wing should be leveled as follows:
a.
If outer wing edge is higher
than the center
deck, loosen jam nut (#6) & tighten turnbuckle
(#7) to shorten it until lower outer wing edge is
level with center deck. Tighten jam nut (#6) to the
correct torque when level.
b.
If outer wing edge is lower
than the center deck,
loosen jam nut (#6) and loosen turnbuckle (#7) to
lengthen it until outer wing edge is level with the
center deck. Tighten jam nut (#6) to the correct
torque when level.
