Section 2: Adjustments
Center & Wing Deck Leveling
These adjustments should be made with the cutter
hooked up to the same tractor that will be used for field
operations or one having the same drawbar height.
Adjust leveling rods as described below.
Front Skid Shoe & Continuous Hinge Positioning
Figure 2-2
Center Deck Leveling
Refer to Figure 2-2 & Figure 2-3 on page 23:
1.
Attach cutter to the tractor that will be pulling the
cutter and position tractor and cutter on level ground.
2.
Raise both wings up and lock into position with
transport locks to keep wings from falling. See
3.
Using hydraulic lift, adjust center deck height so that
the front skids (#7) in Figure 2-2 are 2 to 3 inches
above ground.
4.
Shut tractor down properly before dismounting. Refer
to
5.
On both sides of the center deck are hinge rods (#2).
Measure from ground to bottom of hinge rods at the
front and back. The hinge rods should be 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) several turns.
b. Unscrew adjusting nuts (#4) clockwise an equal
amount to lower front of cutter until both hinge
rods are inclined from front to back by 1" with the
front closer to the ground than the back.
If continuous hinges are too low at the front:
a. Loosen jam nuts (#3).
b. Tighten adjusting nuts (#4) counterclockwise an
equal amount to raise front of cutter until both
hinge rods are inclined from front to back by 1"
with the front closer to the ground than the back.
6.
Raise center deck up to make accessing jam nuts
(#3) and adjusting nuts (#4) easier with wrenches.

NOTE:
Lengthen leveling rods to lower front of
cutter; shorten leveling rods to raise front of cutter.
Park Jack Angle Alignment
Figure 2-1
Park Jack Angle Alignment
Refer to Figure 2-1:
The jack mount angle should be adjusted to position the
park jack vertical while supporting the cutter hitch. This
angle will vary depending on the number and size of
stroke control spacers placed on the lift cylinder rod.
1.
With cutter hitched to a tractor, lower cutter to storage
height.
2.
Shut tractor down properly before dismounting. Refer
to
3.
Install park jack (#7). See
page 21. Check jack angle. If jack is vertical, skip to
step 9, otherwise, proceed with step 4 below.
4.
Remove hex nut (#3), lock washer (#5) and carriage
bolt (#2).
5.
Loosen 1" hex nut (#4). Do not remove.
6.
Rotate jack mount (#1) to align jack as near vertical
as possible.
7.
Replace 1/2"-13 x 1 1/2" GR5 carriage bolt (#2) and
secure with lock washer (#5) and hex nut (#3).
Tighten hex nut to the correct torque.
8.
Tighten 1" hex nut (#4) to 645 ft-lbs.
9.
If moving cutter, skip to step 10. If unhooking cutter,
see
on page 20 for detailed
instructions.
10. If cutter is to be moved, remove park jack (#7) from
hitch frame and attach it to the left-hand wing storage
base. Make sure base of park jack is level with or
lower than the head, especially after the wings are
folded up. See cover picture for correct positioning.

NOTE:
If cutter is not hitched securely to a tractor,
support blocks should be placed under the front
skid shoes to support cutter while aligning the park
jack vertically.
NOTE:
Refer to decal (#6) and instructions below
for jack alignment and torque value instructions.
