!
CAUTION!
Engage parking brake, shut off tractor, remove key and disen-
gage PTO before making any height adjustments!
1.
Lower cutter onto safely supported blocks to desired
cutting height. Be certain cutter is level.
2.
If cutter is equipped with optional hydraulic height ad-
justment, connect cylinder hoses to tractor remote
outlets.
3.
Adjust the cutting height using ratchet jack or hydrau-
lically if equipped with hydraulic cylinder.

Pull-Type Cutting Height
1.
The cutting height can be adjusted by extending or re-
tracting the hydraulic cylinder to the desired cutting
height.
2.
Once the cutter has been leveled, it will remain level
regardless of change in cutting height unless tractor
drawbar height or tailwheel size is changed.
3.
Should the cutter require additional leveling adjust-
ment:
f.
Turn nut on leveling tube counterclockwise to low-
er front of cutter and clockwise to raise front of cut-
ter.
g.
Secure with jam nut.
Deck Attitude Adjustment
Refer to Figure 3-2:
This adjustment is very important. With the deck posi-
tioned at this attitude, the blades will be cutting material
only at the front of the cutter. If the deck is level, or the rear
of the cutter is lower than the front, the blades are subject
to continuous material flow which results in additional
blade wear and horsepower loss as well as more frequent
blade sharpening.
