Definition of Terms
The following terms are used to describe various cut
appearance symptoms.
Ragged Cut
NOTE: Arrow indicates direction of travel.
Ragged cutting occurs when blades of grass are torn or
damaged rather than cut. This is usually caused by
incorrect height-of-cut adjustment, incorrect
bedknife-to-reel adjustment, or dull blades.
Probable Cause Remedy
Incorrect cutting height adjustment. Adjust to the proper height-of-cut. (See “Height-of-Cut (HOC)
Adjustment” on page 8-18.)
Incorrect bedknife-to-reel clearance. Adjust the bedknife-to-reel clearance. (See “Bedknife-to-Reel
Clearance Adjustment” on page 8-17.)
Worn or damaged reel bearings. Replace the reel bearings. (See “Reel Bearing Housing Assembly”
on page 8-34.)
Incorrectly adjusted bearing pre-load. Adjust the bearing pre-load. (See “Reel Bearing Pre-Load
Adjustment” on page 8-19.)
Dull bedknife and/or reel blades. Sharpen the bedknife and reel blades. (Refer to “Parts and
Maintenance Manual.”)
Wavy or rifled bedknife. Grind and adjust the reel and bedknife. (Refer to “Parts and
Maintenance Manual” and see “Bedknife-to-Reel Clearance
Adjustment” on page 8-17.)
