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