ANTI-SCALP ROLLER ADJUSTMENT
The anti-scalp rollers are set at the factory for typical
mowing height, but can be adjusted for high or low cutting
conditions (figure 13).
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.
NOTE: There are four anti-scalp rollers on the outside of the
mower deck and two anti-scalp rollers on the inside of the
mower deck. Make sure all anti-scalp rollers are set at the
same height.
