Backlapping Procedure
See Figures 8-8 through 8-14.
Whenever a reel and bedknife have been ground, or a
new reel or bedknife has been installed, the assembled
reel should be backlapped.
1. Check for damage to the bedknife and reel blades.
(See “Reel and Bedknife Inspection” on page 8-13.)
2. Determine if backlapping or grinding will restore the
proper cutting edge.
3. For optimum performance, use a bedknife grinder to
touch up the blade, then reassemble and adjust the
bedknife to the reel. (See “Bedknife-to-Reel
Adjustment” on page 8-14.)
4. Start the mower.
