BACKLAPPING
Routine reel lapping is part of a general
maintenance plan for reel mowers.
All five reels will rotate at the same time when the
engine is running and reel PTO is engaged.
NOTE:
Even when the engine is OFF, rotating
one reel will cause the others to rotate.
Use the following procedure with the engine off and
the reels disengaged.
1.
Wash the reels and bedknives.
2.
Slightly back off the reel to bedknife
adjustment.
3.
Apply lapping compound to the reels
BEFORE
starting the engine and engaging
the reels.
NOTE: DO NOT apply lapping compound to reels
UNLESS the engine is off and the reels
disengaged. DO NOT apply lapping
compound to rotating reels.
4.
Lower the cutting units so they are firmly on
the ground, apply the parking brake, place
the reel control lever (located under the
seat) in the backlap position. With the
operator in the operating position, start the
engine. DO NOT run the engine in an
enclosed area.
5.
Run the engine at slightly higher than idle
speed. Adjust the reel control knob
anticlockwise to slow the reels to
approximately 200rpm. Engage the reel
drive from the operators position on the
machine.
6.
Backlap reels for several minutes,
periodically disengage reel drive, shut off
engine and check the blade condition. Add
additional backlapping compound and adjust
reel to bedknife clearance. Return to the
operating position and continue backlapping
until all blades are uniformly sharp.
7.
Disengage reel drive, shut off engine and
thoroughly wash all backlapping compound
from reels and bedknives. Apply a thin
coating of oil to all sharpened surfaces.
8.
For a finer cut, file across the front face of
the bedknife to remove any burrs from the
sharp edge.
9.
Adjust the reel to bedknife (see cutting unit
manual).
