Anti-scalp Rollers

Anti-scalp rollers are correctly adjusted when
they are slightly off of the ground when the deck
is at the desired cutting height in the operating
position. Anti-scalp rollers keep the deck in the
proper position to help prevent scalping in most
terrain conditions.
The anti-scalp rollers can be set in three
positions:
• Upper —1-1/2" to 2-1/2" (38 mm -63 mm) grass
• Middle —2-1/2" to 4" (63 mm -102 mm) grass
• Lower — 4" to 6" (102 mm -152 mm) grass.
The rollers must be approximately 1/4" from the
ground.
