4.20 BACKLAPPING ___________________________________________________________
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 bedknife to reel as described in Sections 3.2
and 3.3.
2. Obtain the mechanics (Backlap) key.
a. Make absolutely certain your feet and clothing
are far away from the reel.
b. Make sure the parking brake is “ENGAGED”,
reel levers are “OFF”, backlap switch is “OFF”
and the traction lever is in neutral.
3. Turn all three backlapping knobs counterclockwise
to open
4. Turn backlap key to backlap position and start the
engine. Adjust throttle to minimum RPM.
a. Engage lever for reel to be backlapped. Keep the
other levers in the OFF position.
b. Slowly close backlap knob until reel turns at
desired speed
c. Apply lapping compound with a long handle
brush to high spots first then along entire length
of the reel.
d. 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.
e. When the blades have been evenly honed,
carefully and thoroughly clean off the remaining
lapping compound from the reels and bedknife
before running the reel in forward direction.
5. Repeat the entire process on the other reels.
6. Disengage reel levers, stop the engine, remove and
store the mechanics key.
WARNING
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.
