MISMATCHED CUTTING UNITS _______________________________________

NOTE: Arrow indicates direction of travel.
Probable Cause
HOC inconsistent from one cutting unit to another.
Difference in mower ride height side to side.
12 QUALITY OF CUT
Rifling or tramlining is a pattern of varying cutting
heights, resulting in a wave-like cut appearance,
usually due to heavy contact points across a reel
and/or bedknife.
Remedy
Inspect bedknife and reel. Sharpen or replace reel
and bedknife as necessary.
Install, replace or tighten bedknife screws to proper
torque setting.
Reduce mowing (ground) speed.
Mismatched cutting units is a pattern of varying cut-
ting heights, resulting in a stepped cut appearance,
usually due to mismatched HOC (height-of-cut) ad-
justment from one cutting unit to another.
Remedy
Check/adjust HOC on cutting units.
Check/adjust tire inflation pressure.
