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.
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 cutting
heights, resulting in a stepped cut appearance, usually
due to mismatched HOC (height-of-cut) adjustment from
one cutting unit to another.
Check/adjust HOC on cutting units.
Check/adjust tire inflation pressure.
