Back Lapping of Reel Cutter (Cutting
Cylinder)
Back lapping is work similar to sharpening a
cooking knife. If the edges of the reel cutter
(cutting cylinder) and the bed knife (bottom
blade) become blunt and make cutting difficult,
both the reel cutter (cutting cylinder) and the bed
knife (bottom blade) should be simultaneously
sharpened by reversing the reel cutter (cutting
cylinder) with an abrasive paste applied.
However, back lapping is a temporary measure
and would not restore the sharpness completely.
If the edges of the reel cutter (cutting cylinder)
and the bed knife (bottom blade) become blunt
and make cutting difficult, follow the steps below
to perform back lapping.
Caution
Both the reel cutter (cutting cylinder) and the
bed knife (bottom blade) are edged tools.
Handle them carefully, since they could cut
your hands and feet.
Caution
Be careful not to inhale exhaust gas during
back lapping.
Caution
During back lapping, the reel cutter (cutting
cylinder) rotates.
Keep hands and feet away from moving
parts.

Note:
The mixing ratio for the abrasive, in volume,
is one part back lapping powder to three or
four parts oil.
Caution
Before adjusting the blade engagement, be
sure to set the reel rotation/stop switching
lever for the reel motor (attached to the
mower unit) to the "Stop" position.
Before cutting newspaper as a test, be sure
to stop the engine and wear gloves to protect
your hands.
Pay attention not to let the reel cutter (cutting
cylinder) catch your gloves. Otherwise, you
may injure your hand or fingers.
Important
For checking the sharpness of the blade,
adjust the blade engagement after cutting
grass.
