Scalping
NOTE: Arrow indicates direction of travel.
Scalping is a condition in which areas of grass are cut
noticeably shorter than the surrounding areas, resulting in
a light green or even brown patch. This is usually caused
by an excessively low height-of-cut setting and/or uneven
turf.
Probable Cause Remedy
Improper tire pressure. Set front machine tires at 16–20 psi (110–138 kPa), rear machine
tires at 10–12 psi (69–83 kPa), and caster tires at 20–25 psi
(138–172 kPa).
HOC (height-of-cut) settings are lower than normal. Check and adjust the HOC settings. (See “Deck Leveling
Adjustment” on page 8-4.)
Front deck and wing deck are not level. Level decks. (See “Deck Leveling Adjustment” on page 8-4.)
Incorrect deck rake. Set proper deck rake. (See “Deck Rake Adjustment” on page 8-4.)
Broken or worn anti-scalp-wheels. Replace anti-scalp-wheels. (See “Anti-Scalp Wheels” on
page 8-29.)
Turf too uneven for the mower to follow. Change mowing direction.
Cutting too much grass at one time. Mow more often.
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
