ADJUSTMENT
NOTE: The anti-scalp rollers are intended to
prevent lawn scalping, not to control cutting
height. All anti-scalp rollers should be set at
the same height.
See figure 19 for anti-scalp locations on
models915044, 046, 048, 050. See figure 20
for anti-scalp locations on model 915042.
There are two positions:
• Highest Position: Use to disable
anti-scalp feature.
• Lowest Position: Use for all cutting
positions.
In the lowest position the anti-scalp rollers will
touch the ground.
