backlapping, turn the reels off by moving the
Raise/Lower Mow control rearward and stop the
engine. After completing adjustments, repeat

want to backlap.

Forward (F) position, replace the cover, and
wash all lapping compound off of the cutting
units. Adjust cutting unit reel to bedknife as
needed. Move the cutting unit reel speed control
to the desired mowing position.
Important:
If the backlap lever is not
returned to the Forward (F) position after
backlapping, the cutting units will not raise
or function properly.
