Step Cutting
NOTE: One cutting unit width shown. Arrow indicates
direction of travel.
Step cutting occurs when grass is cut taller on one side of
the reel than the other. This is usually caused by
mechanical wear or an incorrect roller adjustment.
Probable Cause Remedy
HOC (height-of-cut) settings are different from one side of the
reel to the other.
Check HOC adjustment. (See “Height-of-Cut Adjustment (HOC)” on
page 8-17.)
Worn roller bearings. Check/replace roller bearings. (See “Cutting Unit Front Roller” on
page 10-8.)
Worn reel bearings. Check/replace/adjust reel bearings. (See “Reel Bearing Pre-Load
Adjustment” on page 8-18.)
Reel-to-bedknife contact is different from one side of the cutting
unit to the other.
Check reel to bedknife contact. (See “Bedknife-to-Reel Adjustment”
on page 8-14.)
Cutting unit movement is restricted. Check/remove cutting unit movement restriction.
Variations in turf density. Change mowing direction.
