Backlapping the Cutting Units

Contact with the reels or other moving parts can
result in personal injury.

Keep fingers, hands, and clothing away from the
reels or other moving parts.

Caution

1. Position the machine on a clean, level surface, lower the

cutting units, stop the engine, engage the parking brake,
and remove the ignition key.

2. Remove the reel motors from the cutting units and

disconnect and remove the cutting units from the lift
arms.

3. Connect the backlapping machine to the cutting unit by

inserting a piece of 3/8 in. square stock into the splined
coupling at the right end of the cutting unit.

Note: Additional instructions and procedures on
Backlapping are available in the Toro Sharpening Reel &
Rotary Mowers Manual, Form No. 80-300PT.

Note: For a better cutting edge, run a file across the 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.
