7. To make an adjustment to the cutting units while
backlapping, turn off the reels by pushing in the reels
ON/OFF switch on instrument panel to OFF position and
stopping the engine. After adjustments have been com-
pleted, repeat steps 4 through 6.

reel speed controls to the desired mowing setting, and
wash all lapping compound off the cutting units.

front face of the bedknife when the lapping operation is
completed. This will remove any burrs or rough edges
that may have built up on the cutting edge.
