Backlapping

Note: See traction unit Operator's Manual for complete
operating instructions.
Note: Lapping is not intended to be a reconditioning pro-
cess to correct severely nicked or rounded blades, rifling
or taper. If, after 5 minutes of lapping, the edge is not re-
stored, it is time to grind the reel.
TO AVOID PERSONAL INJURY OR DEATH:
– Never place hands or feet in reel area
while engine is running.
– While backlapping, reels may stall and
then restart.
– Do not attempt to restart reels by hand or
foot.
– Do not adjust reels while engine is
running.
– If reel stalls, stop engine before
attempting to clear reel.
Note: Backlap either the front cutting units together or
the rear ones together.
1. Position machine on a clean, level surface, lower the
cutting units, stop the engine, engage the parking
brakes, move enable/disable switch to disable position
and remove key from ignition switch.
2. Unlock and raise seat to expose controls.
3. Make initial reel to bedknife adjustments appropriate
for backlapping on all cutting units. Start engine and set
engine to low idle speed.
4. Set reel speed control to Position P. Select either front
or rear on backlap switch to determine which units to
backlap.

eration on designated reels.

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

setting and wash all lapping compound off cutting units.
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 opera-
tion is completed. This will remove any burrs or
rough edges that may have built up on the cutting
edge.
