your desired speed.

want to backlap.

the Mow position, lower the floor panel, and wash
all lapping compound off of the cutting units. Adjust
the cutting unit reel-to-bedknife contact as needed.
Move the cutting unit reel speed control to the desired
mowing position.
Important: If the backlap switch is not returned
to the F (Mow) position after backlapping, the
cutting units will not raise or function properly.
Note: For a better cutting edge, run a file across
the front face of the bedknife after lapping. This will
remove any burrs or rough edges that may have built
up on the cutting edge.
