2.
Raise the rear of the cutting unit and place a
block under the bedknife.
3.
Remove the 2 nuts securing each roller bracket
and spacer to each side-plate mounting flange.
4.
Lower the roller and screws from the side-plate
mounting flanges and spacers.
5.
Place the spacers onto the screws on the roller
brackets.
6.
Secure the roller bracket and spacers to
underside of side plate mounting flanges with
the nuts previously removed.
7.
Verify that the bedknife-to-reel contact is correct.
Tip the mower to expose the front and rear
rollers and bedknife.
Note:
The position of the rear roller to the reel
is controlled by the machining tolerances of the
assembled components; therefore, paralleling is
not required. A limited amount of adjustment is
possible by setting the cutting unit on a surface
plate and loosening the side-plate mounting cap
screws
(Figure
16). Adjust and tighten the cap
screws. Torque the cap screws to 37 to 45 N-m
(27 to 33 ft-lb).

Adjusting the Turf-Compensation
Settings
The turf-compensation spring transfers the weight
from the front to the rear roller. This helps to reduce
a wave pattern in the turf, also known as marcelling
or bobbing.
Important:
Make the spring adjustments with the
cutting unit mounted to the traction unit, pointing
straight ahead and lowered to the shop floor.

Make sure that the hairpin cotter is installed in
the rear hole in the spring rod
