DANGER!
Engage parking brake, disengage PTO, shut off tractor and re-
move key before proceeding. Ensure that all moving parts have
come to a complete stop before dismounting from the tractor.
!
CAUTION!
Wear a pair of gloves when performing thisoperation. Go to the
back of the cutter and carefully rotate each blade to the position
shown in Figure 3-1. Avoid direct contact with the cutting edge
of the blade.
5. Measure the distance from the end (cutting tip) of the
blade to the ground surface. This distance is the nom-
inal cutting height, see Figure 3-3.
Refer to Figure 3-4:
6. If the cutting height is too high or too low, the tailwheel
must be adjusted as follows:
a. Use the tractors 3-point hydraulic control to lift the
cutter such that the tailwheel clears the ground
surface.
b. Remove attaching hardware; bolt (#1), nut (#2),
and lock washer (#3).

c. Adjust the tailwheel up or down to the desired cut-
ting height and replace the attaching hardware.
d. Lower the 3-point hitch and repeat steps 3 and 4
to be sure the deck is level and the top link is ad-
justed properly.
7. Re-adjust the tractors 3-point hydraulic control such
that the front of the cutter is 1" lower than the rear.

NOTE: This adjustment is very important. With the
deck positioned 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 mate-
rial flow which results in additional blade wear and
horsepower loss as well as more frequent blade
sharpening. Refer to Figure 3-5.
