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 spring adjustments with the cutting
unit mounted to the traction unit, pointing straight
ahead and lowered to the shop floor.
1. Make sure that the hairpin cotter is installed in the rear
hole in the spring rod (
Figure 19 ).

2. Tighten the hex nuts on the front end of the spring rod
until the compressed length of the spring is 12.7 cm (5
inches); refer to
Figure 19 .
Note:
When operating on rough terrain decrease the
spring length by 1.3 cm (1/2 inch). Ground following
will be slightly decreased.
Note:
You will need to reset the turf compensation
setting if the HOC setting or the aggressiveness-of-cut
setting is changed.
