8. If the reels stall or become erratic while backlapping,
increase the throttle speed until the reel stabilizes.
9. To make an adjustment to the cutting units while
backlapping, turn the reels off by pressing the rear
of the lift switch; move the PTO switch to the OFF
position, and stop the engine. After completing
adjustments, repeat steps through 8.
10. Repeat the procedure for all cutting units you want to
backlap.
11. When finished, return the backlap levers to the
Mow position, lower the hood, and wash all lapping
compound off of the cutting units. Adjust cutting unit
reel to bedknife as needed. Move the cutting unit reel
speed controls to the desired mowing position.
Important: If the backlap switch is not returned
to the Off position after backlapping, the cutting
units will not raise or function properly.
Note: Additional instructions and procedures on
backlapping are available in the TORO Sharpening
Reel & Rotary Mowers Manual Form No. 80–300SL.
Note: For a better cutting edge, run a file across
the front face of the bedknife after lapping. This will
remove any burrs or rough edges that may have built
up on the cutting edge.
