Back Lapping
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.
Warning
During back lapping, the reel cutter (cutting
cylinder) rotates.
Keep hands and feet away from moving parts.
Caution
Do not perform back lapping with any other
persons.
Have the following items ready: Strips of
newspaper, Abrasive [Back lapping powder
mixed with oil; or gel compound (Baroness
genuine abrasive)], Brush.

handle ready.
Caution
When handling the reel cutter (cutting
cylinder) or bed knife (bottom blade), wear
gloves to protect your hands.
However, pay attention not to let the reel
cutter (cutting cylinder) catch your gloves, etc.
Otherwise, you may injure your hand or
fingers.
Important
Check the sharpness of the blade by checking
the blade engagement after cutting grass.
Stop the engine.
