Level Cutter Decks
These adjustments should be made with your cutter
hooked to the tractor that will be operating the unit or to a
tractor having the same drawbar height.
Level Center Deck
Refer to Figure 2-2 & Figure 2-3
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 skid shoes (#2) are 2 to 3 inches above ground.
3. Wait for blades to come to a complete stop and then
fold wing up to transport position.
4. Shut tractor down properly before dismounting
according to
5. Lock wing in the up position with the transport pin.
on page 34 for instructions.
6. On both sides of center deck, there 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.
If continuous hinges are too high at the front:
a. Loosen jam nuts (#5) several turns.
b. Unscrew adjusting nuts (#3) an equal amount to
lower front of cutter until both hinges are 1" lower
in the front than in the back.
If continuous hinges are too low at the front:
a. Loosen jam nuts (#5).
b. Tighten adjusting nuts (#3) an equal amount to
raise front of cutter until both hinges are 1" lower
in the front than in the back.
7.
Be sure left and right leveling rods have equal
amounts of tension and then retighten jam nuts (#5)
against lock washers (#4) and adjusting nuts (#3).

IMPORTANT:
See
. Loosening adjusting
nuts (#3) will lengthen leveling rods and lower front
of cutter. Tightening adjusting nuts (#3) will shorten
leveling rods and raise front of cutter.
NOTE:
1" measurement can be lowered or raised
depending on cutting conditions.

Level Wing Deck
Refer to Figure 2-4:
The wing section will need adjusting if wing top is not
level with center deck top when wing is unfolded.
1. Start tractor and lower wing down. Refer to
on page 36 for instructions on how to lower
wing.
2. Pull cutter straight forward six to ten feet to allow
outer wing wheels to properly align themselves.
3. Check wing top with a level to see if they are level with
the top of the center deck. If the outer edge of wing
top is higher or lower than the center deck, then the
wing should be leveled as follows:
a.
If outer wing edge is higher
than the center
deck, loosen jam nut (#7) and tighten turnbuckle
(#8) to shorten it until lower outer wing edge is
level with center deck. Tighten jam nut (#7) to the
correct torque when level.
b.
If outer wing edge is lower
than the center deck,
loosen jam nut (#7) and loosen turnbuckle (#8) to
lengthen it until outer wing edge is level with the
center deck. Tighten jam nut (#7) to the correct
torque when level.
