Backlapping
DANGER
TO AVOID PERSONAL INJURY OR DEATH:
D
Never place hands or feet in the reel area
while the engine is running. Stay away from the
cutting reels when backlapping.
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.
1. Position machine on a clean and level surface, lower
cutting units, stop engine, engage parking brake and re-
move key from the ignition switch.
2. On all cutting units, make initial reel to bedknife ad-
justments appropriate for backlapping.
IMPORTANT: Do not attempt to rotate the direction-
al valve lever on the hydraulic mow control manifold
when the engine or reels are running.
3. Raise seat, locate hydraulic mow control manifold
and rotate directional valve lever fully to the R (backlap)
position (Fig. 22). Rotate flow control valve knob to posi-
tion 1.
4. Start engine and run at
low idle speed
.
5. With the mow speed limiter in the mow position,
move the PTO switch to the ON position. Press the lift
switch to start the backlapping operation on the desig-
nated reels.
6. Apply lapping compound to cutting reels with a long
handle brush (see Special Tools). Never use a short
handled brush to apply lapping compound.
CAUTION
Be careful when backlapping the reel because
contact with the reel or other moving parts can
result in personal injury.
7. To make a cutting unit adjustment while backlapping,
turn reels OFF, shut off engine and wait for all machine
and cutting unit motion to completely stop. Then, after
cutting unit adjustments have been completed, repeat
steps 4 through 6.

8. When the backlap operation is completed, shut off
engine and rotate directional valve lever fully (90
o
from
the backlap position) to the F (forward) position. Also,
rotate flow control valve knob to correct mowing posi-
tion.
9. Wash all lapping compound from the cutting units.
10.For a better cutting edge, run a file across the front
face of the bedknife when the lapping operation is com-
pleted (Fig. 23). This will remove any burrs or rough
edges that may have built up on the cutting edge.
