Backlapping - Toro Reelmaster 6700-D Operator's Manual

Backlapping

Danger
The reels may stall while backlapping and could
restart suddenly. Contact with the reels during
backlapping will cause personal injury.
Never place hands or feet in the reel area while
the engine is running.
Never attempt to turn the reels by hand or foot
or touch the reels while backlapping.
Never change engine speed while backlapping.
Only backlap at idle speed.
Stop the engine and move the desired reel speed
selector knob(s) one position closer to "13."
Note: When backlapping, the front units all operate
together, and the rear units operate together.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking brake,
and move the Enable/Disable switch to disable position.
2. Unlock and raise the seat to expose controls.
3. Locate the reel speed selector knobs and backlap knobs
(Fig. 71). Rotate the desired backlap knob(s) to the
backlap position and the desired reel speed selector
knob(s) to position "1."

carefully remove the burr without dulling the cutting
edge (Fig. 73).
