Section 2: Adjustments
Center & Wing Section Leveling
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 2-1 & Figure 2-2:
1.
Attach cutter to tractor and position it on level ground.
2.
Raise both wings to locked position.
3.
Using hydraulic lift, adjust center deck height so that
the front skids (#2) are 2 to 3 inches above ground.
4.
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. Unscrew adjusting nuts (#4) an equal amount to
lengthen both leveling rods until hinges (#1) are
inclined from front to back by 1" with the front
being closer to the ground than the back.
NOTE:
Unscrewing coupler nuts (#4) will lengthen
leveling rods and lower front of cutter. Tightening
coupler nuts (#4) will shorten leveling rods and raise
front of cutter.
If continuous hinges are too low at the front:
a. Loosen jam nuts (#3) several turns.
b. Tighten adjusting nuts (#4) an equal amount to
shorten both leveling rods until hinges (#1) are
inclined from front to back by 1" with the front
being closer to the ground than the back.
5.
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 nut (#3).
