RIFLING OR TRAMLINING ___________________________________________________
5.10 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 overtorqued 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 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.
Difference in mower ride height side to side.
Check/adjust tire inflation pressure.
