D. Adjusting the Height of Cut
1. Rotate the cutting unit vertical and place the gauge bar
across front and rear rollers (Fig. 14).
2. Loosen the locknuts securing the height-of-cut
brackets to each end of the cutting unit (Fig. 14).
3. Set the head of the height of cut screw on the gauge
bar to the desired height of cut, making this
measurement from the bar face to the underside of the
screw head.
4. Place the bar across the front and rear rollers and
adjust the tap bolt until the underside of the screw
head engages the bedknife cutting edge (Fig. 14).
Important Do step 3 on each end of the bedknife.
Tighten the height-of-cut adjustment locknuts on both
ends. Recheck the adjustment.
Note: Same procedure is used when Front Height of Cut
kit, Part No. 104–8205 is installed on cutting unit.

E. Adjusting Turf
Compensation Spring
The Turf Compensation Spring (Fig. 15), connecting
carrier frame to cutting unit, controls the amount of
fore-aft rotation available for the cutting unit
The Turf Compensation Spring also transfers weight
from the front to rear roller. This helps to reduce a
wave pattern in the turf, also known as bobbing.
Important Make spring adjustments with cutting unit
mounted to traction unit and lowered to shop floor. Refer
to Traction Unit Operator’s Manual for mounting
instructions.
1. Tighten lock nut on rear of spring rod until the gap (C)
between rear of spring bracket and front of washer is
1.25” (32 mm) (Fig. 15).

2. Tighten hex nuts on front end of spring rod until the
compressed length (A) of spring is 6.25 (159 mm)
(Fig. 15).
Note: As compressed spring length (A)
decreases, weight transfer from front
roller to rear roller increases and
carrier frame/cutting unit rotation angle
(B) decreases.
Note: As gap (C) between spring bracket and
washer increases, cutting unit ground
clearance decreases and carrier
frame/cutting unit rotation angle (B)
increases.
