Mismatched Cutting Units
NOTE: Arrow indicates direction of travel.
Mismatched cutting units cause a pattern of varying
cutting heights, resulting in a stepped cut appearance,
usually due to a different HOC (height-of-cut) adjustment
from one cutting unit to another.
Probable Cause Remedy
HOC inconsistent from one cutting unit to another. Adjust HOC on cutting units to same height. (See “Height-of-Cut
(HOC) Adjustment” on page 8-18.)
Check condition of cutting unit frame and/or mower frame. Repair or
replace as needed.
Difference in reel motor speeds. Check operation of reel motor(s) and repair/replace as necessary.
(See “Reel Motor” on page 8-28.)
Difference in mower ride height from side-to-side. Check/adjust tire inflation pressure. (Refer to “Parts and
Maintenance Manual.”)
