Rifling or Tramlining
Grass Graining
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 the reel and/or bedknife.
Probable Cause Remedy
Reel and/or bedknife unevenly worn. Inspect bedknife and reel. Grind or replace as needed. (See “Reel
and Bedknife Inspection” on page 8-17 and refer to “Parts and
Maintenance Manual.”)
NOTE: Arrow indicates direction of travel.
Grass graining is a directional orientation of grass blades
and/or stems usually due to mowing in one direction or
constant traffic in one direction.
Probable Cause Remedy
Mowing in the same direction. Mow against the grain or change the mowing pattern.
Constant traffic direction. Use a brush attachment on the cutting unit.
Nature of grass growth influenced by water. Use Turf Groomer
®
or vertical mower.
