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 “Tractor Shutdown Procedure” on page 14.
3. Install park jack (#7). See “Park Jack Assembly” on
page 14. Check jack angle. If jack is not vertical,
proceed with step 4 below.
4. Remove 1/2" 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 park jack (#7) 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 “Unhook Rotary Cutter” on page 25 for detailed
instructions.
10. If cutter is to be moved, remove park jack (#7) from
hitch frame and attach it to the weight box storage
base.

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 values.
Leveling Center Deck & Wing
These adjustments should be made with your cutter
hooked to the tractor operating the unit or to a tractor
having the same drawbar height.
Center Deck Leveling
Refer to Figure 2-2 & Figure 2-3 on page 27:
1. Attach cutter to tractor and park on level ground.
2. Raise wing up and lock into position with transport
lock to keep wings from falling.
3. Using hydraulic lift, adjust center deck height so that
the front skids (#5) are 2 to 3 inches above ground.
4. Shut tractor down properly before dismounting. Refer
to “Tractor Shutdown Procedure” on page 14.
5. 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) several turns.
b. Unscrew adjusting nuts (#5) an equal amount to
lower front of cutter until both hinges are inclined
from front to back by 1" with the front being 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 (#5) an equal amount to
raise front of cutter until both hinges are inclined
from front to back by 1" with the front being closer
to the ground than the back.
6. Be sure left and right leveling rods (#2) have equal
amounts of tension and then re-tighten jam nuts (#3)
against lock washers (#4) and adjusting nuts (#5).
NOTE: Loosening adjusting nuts (#5) will lengthen
leveling rods (#2) and lower front of cutter.
Tightening adjusting nuts (#5) will shorten leveling
rods (#2) and raise front of cutter.
