To adjust anti-scalp rollers
Anti-scalp rollers are properly adjusted when
they are just slightly off of the ground when
the deck is at the desired cutting height in the
operating position. Anti-scalp rollers then
keep the deck in the proper position to help
prevent scalping in most terrain conditions.
IMPORTANT INFORMATION
Adjust Anti-scalp rollers with the
mower on a flat level surface.

The anti-scalp rollers can be set in three
positions.
¥ Upper position 1.5 to 3 (38 to 76 mm)

grass.
¥ Lower position 4.5 to 6 (114 to 152 mm)
grass.

The anti-scalp rollers can be set in two
postions.
