NOTE: Arrow indicates direction of travel.
Rifling or tramlining is a pattern of different cutting
heights, that causes a cut appearance like a wave.
The cause of rifling can be a heavy contact point
across a reel or a bedknife.
Possible Cause
Solution
The reel or the bedknife are worn at different levels.
Inspect the bedknife and reel. Sharpen or replace
the reel and bedknife as necessary.
The bedknife screws are not included or loose, or
over tightened.
Install, replace or tighten the bedknife screws to the
correct torque setting.
The cut (ground) speed is higher than normal.
Decrease the cut (ground) speed.
NOTE: Arrow indicates direction of travel.
Mismatched cutting units is a pattern of different cut-
ting heights, that give the grass a stepped appear-
ance. This appearance is normally because of a
mismatched HOC (height-of-cut) adjustment from
one cutting unit to another unit.
Possible Cause
Solution
HOC is different from one cutting unit to another cut-
ting unit.
Check and adjust HOC on cutting units.
Difference in mower ride height side to side.
Check and adjust the pressure of the tyres.
