Rifling or tramlining is a pattern of different cutting heights
that gives the grass an appearance like a wave. This
appearance is normally because of heavy contact points
across a reel and bedknife.
Check and adjust the HOC on cutting units to same
height.
Install, replace or tighten the bedknife screws to the
correct torque.
Reduce the cut (ground) speed.
