12 QUALITY OF CUT
12.8 RIFLING OR TRAMLINING ___________________________________________
12.9 MISMATCHED CUTTING UNITS _______________________________________
NOTE: Arrow indicates direction of travel.
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.
Probable Cause Remedy
Reel and/or bedknife unevenly worn. Inspect bedknife and reel. Sharpen or replace reel
and bedknife as necessary.
Missing, loose, or over torqued bedknife screws. Install, replace or tighten bedknife screws to proper
torque setting.
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
NOTE: Arrow indicates direction of travel.
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.
Probable Cause Remedy
HOC inconsistent from one cutting unit to another. Check/adjust HOC on cutting units.
Difference in mower ride height side to side. Check/adjust tire inflation pressure.
