Backlapping

DANGER
TO AVOID PERSONAL INJURY OR DEATH:
D Never place hands or feet in the reel area
while the engine is running.
D When backlapping, run engine at idle speed
only.
D While backlapping, the reels may stall and
then restart.
D Do not attempt to restart reels by hand or foot.
D Do not adjust reels while the engine is
running.
D If a reel stalls, stop engine before attempting
to clear the reel.
D Reel motors are connected in series: rotating
one motor causes rotation in other motors.
NOTE: Additional instructions and procedures on
backlapping are available in the Toro General Service
Training Book, Reel Mower Basics (part no. 09168SL).
1. Position the machine on a level surface, lower the
cutting units, stop the engine and engage the parking
brake.
2. Raise the operator seat to access hydraulic mow
manifold.
3. Locate the reel speed control and backlap lever on
the hydraulic mow manifold (Fig. 11). Rotate the reel
speed control to position "1" and the backlap lever to the
R (backlap) position.
4. Make initial reel to bedknife adjustments appropriate
for backlapping on all cutting units which are to be back-
lapped.
5. Start engine and run at low idle speed.
6. Use joystick on the control console to engage the
cutting units.
IMPORTANT: To prevent damage to the reel, do not
rotate the backlap lever from the backlap position to
the mow position while the engine is running.
7. Apply lapping compound to cutting unit blades with
a long handle brush (see Special Tools in this chapter)
(Fig. 12). Never use a short handled brush to apply lap-
ping compound.

8. If reels stall or become erratic while backlapping,
stop backlapping by disengaging the PTO with the joys-
tick. Once the reels have stopped, move the reel speed
selector knob one position closer to "9." Resume back-
lapping by engaging the PTO with the joystick.
