ANTI-SCALP ROLLER
ADJUSTMENT
(Figure 13)
The anti-scalp rollers are set at the factory for
typical mowing height, but can be adjusted for
high or low cutting conditions.
Anti-Scalp rollers are intended to prevent
lawn scalping, not to control cutting height.
For a very high cutting height, set the anti-
scalp rollers in the lowest position on the
bracket.
For a very low cutting height, set the anti-
scalp rollers in the highest position on the
bracket.
