To prevent injury, keep hands, feet and
clothing away from rotating reels.
When the backlap switch is in the
REVERSE position, the reels will turn
whether mowers are up or down and
the operator is on or off the seat.
Carbon Monoxide in exhaust fumes can
be fatal when inhaled, never operate an
engine without proper ventilation.
WARNING
4.19 BACKLAPPING
Note:
The backlapping feature is an optional kit
that must be first installed on the tractor.
Check the reel and bedknife to determine if
backlapping or grinding will restore the cutting
edge.
If wear or damage is beyond the point where the
cutting edges can be corrected by the lapping
process, they must be reground.
To Backlap:
1.
Adjust reel to bedknife as described in
Sections 3.4 and 3.5.
2.
Lower the reels to the ground.
3.
Open the hood and turn the backlap
switch to “REVERSE” rotation. Close
hood.
a. Make absolutely certain your feet and
clothing are far away from the reel.
b. Make sure the parking brake is
“ENGAGED”, reel switch is “OFF”,
backlap switch is “OFF” and the traction
pedal is in neutral.
c. Move the Forward / Reverse switch to
“REVERSE”.
d. Start the engine. Adjust throttle just
above minimum RPM and place the reel
switch in “ON” position.
4.
Adjust the backlapping valve located
under the left rear of the machine, to the
desired speed.
5.
Apply lapping compound with a long
handle brush to high spots first then
along entire length of the reel.
6.
Continue lapping and at the same time
make a slight adjustment on the reel until
there is a uniform clearance along the full
length of the cutting edges.
7.
When the blades have been evenly
honed, carefully and thoroughly clean off
the remaining lapping compound.
8.
Disengage reel switch and stop the
engine. Open the hood and return
