Step Cutting
NOTE: Arrow indicates direction of travel.
Step cutting occurs when grass is cut taller on one side of
a cutting unit than on the other, or on one side of the
mower than on the other. This is usually caused by
mechanical wear or an incorrect roller or deck caster
adjustment.
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 or spacers are different from one
side of a cutting unit to the other, or from one cutting unit to
another. Check HOC adjustment of cutting units.
Front deck and wing deck are not level. Level decks. (See “Deck Leveling Adjustment” on page 8-4.)
Worn deck caster wheels or deck swivel caster wheels. Check/replace caster wheels. (See “Fixed Caster Wheels” on
page 8-28.) Check/replace deck swivel caster wheels. (See
“Swivel Caster Wheels” on page 8-27.)
Uneven caster wheel arms. Level caster wheel arms. (See “Deck Leveling Adjustment” on
page 8-4.)
Cutting unit movement is restricted. Check/remove cutting unit movement restriction.
Variations in turf density. Change mowing direction.
Incorrect weight transfer adjustment, cutting units have too much
or too little weight on them. Use weight transfer knob to transfer weight on or off cutting units.
(See “Weight Transfer Adjustment” on page 5-31.)
Mower frame is bent. Repair or replace as needed.
