Backlapping the Cutting Unit

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

reels or other moving parts.
• Stay away from the reel while backlapping.
• Never use a short handled paint brush for
backlapping. Part No. 29-9100 Handle assembly
complete or individual parts are available from
your local Authorized Toro Distributor.
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 inch square stock into the
splined coupling in the end of the cutting unit.
Note: Additional instructions and procedures on
Backlapping are available in your traction unit Operator's
Manual and the Toro Sharpening Reel and Rotary Mowers
Manual, Form Number 80-300PT.
Note: For a better cutting edge, run a file across the

operation is completed. This will remove any burrs or
rough edges that may have built up on the cutting edge.
