Page 77: Quality Of Cut 12
QUALITY OF CUT 12 12Quality of Cut 12.1 QUALITY OF CUT PROBLEM SOLVING________________________________________ Make a “test cut” to check the performance of the mower before you start the repairs. This area must have turf conditions that are known and do not change across the area. This type of area allows an accurate inspection of the perfomance of the mower to be made. -
Page 78: Marcelling
12 QUALITY OF CUT 12.3 MARCELLING ____________________________________________________________ Marcelling is a repeated pattern of different cutting heights, that causes an appearance that is like a wave. In most cases, the wave tip-to-tip distance is 2 in. (5 cm) or less. NOTE: Arrow indicates direction of travel. Probable Cause Remedy The cut (ground) speed is higher than normal. -
Page 79: Step Cutting
QUALITY OF CUT 12 12.4 STEP CUTTING____________________________________________________________ Step cutting occurs when grass is cut higher on one side of a cutting unit than the other side. Step cutting can occur when one cutting unit is higher than another cutting unit. The wear of mechanical parts or an incorrect roller adjustment can cause step cutting. -
Page 80: Scalping
12 QUALITY OF CUT 12.5 SCALPING _______________________________________________________________ Scalping is a condition in which areas of grass are cut shorter than the adjacent areas. The area can be light green or brown. A low HOC setting or turf that is not level can cause scalping. -
Page 81: Stragglers
QUALITY OF CUT 12 12.6 STRAGGLERS ____________________________________________________________ Stragglers are separated blades of grass that are not cut, or are cut incorrectly. NOTE: Arrow indicates direction of travel. Probable Cause Remedy Edge of the cutting blade(s) are not sharp. Sharpen the blade(s). The bedknife is not adjusted correctly. -
Page 82: Streaks
12 QUALITY OF CUT 12.7 STREAKS ________________________________________________________________ A streak is a line of grass that is not cut. The cause of a streak can be a damaged blade.

Page 84: Rifling Or Tramlining
12 QUALITY OF CUT 12.9 RIFLING OR TRAMLINING __________________________________________________ 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. NOTE: Arrow indicates direction of travel. -
Page 85: Mismatched Cutting Units
QUALITY OF CUT 12 12.10 MISMATCHED CUTTING UNITS ______________________________________________ Mismatched cutting units is a pattern of different cutting heights, that gives the grass a stepped cut appearance.
