    CUTTING UNIT Component Location Troubleshooting Cutting unit troubleshooting is broken down into two areas: Quality of Cut Appearance and Mechanical. Quality of Cut Appearance Troubleshooting, as the name states, evaluates the mower’s performance by the visual appearance of the cut delivered by the mower. Undesirable patterns and other conditions noted may be caused by various mechanical, environmental (variations in turf, grass conditions, weather, etc.), or operating...
  • Page 104 CUTTING UNIT Definition of Terms The following terms are used to describe various cut appearance symptoms. Washboarding Washboarding is a cyclical pattern of varying cutting heights, resulting in a wave-like cut appearance. In most cases, the wave tip-to-tip distance is approximately 6— 8 inches (15—20 cm).
  • Page 105 CUTTING UNIT Marcelling Marcelling, like washboarding, is a cyclical pattern of varying cutting heights, resulting in a wave-like cut appearance. In most cases, the wave tip-to-tip distance is 2 inches (5 cm) or less. TN0220 NOTE: One cutting unit width shown. Arrow indicates direction of travel.
  • Page 106 CUTTING UNIT Step Cutting Step cutting is grass that is cut taller on one side of the reel than the other. This is usually caused by mechanical wear or an incorrect roller adjustment. TN0221 NOTE: One cutting unit width shown. Arrow indicates direction of travel.
  • Page 107 CUTTING UNIT Scalping Scalping is areas of grass cut noticeably shorter than the surrounding areas, resulting in a light green or even brown patch. This is usually caused by an excessively low height-of-cut setting and/or uneven turf. TN0222 NOTE: One cutting unit width shown. Arrow indicates direction of travel.
  • Page 108 CUTTING UNIT Stragglers Stragglers are scattered blades of uncut or poorly cut grass. TN0223 NOTE: One cutting unit width shown. Arrow indicates direction of travel. Probable Cause Remedy Bedknife improperly adjusted. Adjust bedknife. (See “Bedknife-to-Reel Adjustment” on page 8-13.) Dull cutting edges. Sharpen reel and bedknife.
  • Page 109 CUTTING UNIT Streaks A streak is a line of uncut grass. This is usually caused by a nicked or bent bedknife. TN0224 NOTE: One cutting unit width shown. Arrow indicates direction of travel. Probable Cause Remedy Damaged bedknife. Replace bedknife. (See “Bedknife” on page 8-17.) Damaged or unevenly worn reel.
  • Page 110 CUTTING UNIT Windrowing Windrowing is the deposit of clippings concentrated at one end of the cutting unit, forming a line in the direction of travel. TN0225 NOTE: One cutting unit width shown. Arrow indicates direction of travel. Probable Cause Remedy Grass is too tall.
  • Page 111 CUTTING UNIT Rifling or Tramlining 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. TN0987 NOTE: One cutting unit width shown. Arrow indicates direction of travel.
