Mismatched Cutting Units
NOTE: Arrow indicates direction of travel.
Mismatched cutting units is a pattern of varying cutting
heights, resulting in a stepped cut appearance, usually
due to mismatched HOC (height-of-cut) adjustment from
one cutting unit to another.
Probable Cause Remedy
HOC inconsistent from one cutting unit to another. Check/adjust HOC on cutting units to same height. (Refer to
“Safety, Operation, and Maintenance Manual.”)
Check condition of deck and/or frame. Repair or replace as needed.
Difference in rotary cutting unit speeds. Check operation of rotary cutting motor(s) and repair/replace as
necessary. (See “Cutting Unit/Charge Pump Test” on
page 6-31.)
Difference in mower ride height side to side. Check/adjust tire inflation pressure. (Refer to “Safety, Operation,
and Maintenance Manual.”)
Check/adjust for even mower weight distribution. (See “Weight
Transfer Circuit” on page 4-57.)
