Toro
Sharpening Reel and Rotary Mowers Manual
, Form No.

Stay away from the reel while backlapping.
•
Never use a short handled paint brush for

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.
