On-site sharpening in the field:
Stop!
Remove battery from drill and don a pair of
gloves.
Cut-resistant butcher’s gloves are best, but if
unavailable heavy leather work gloves are
recommended.

the drill).
b.
Using a
Johnny's 9175 Round Diamond Hone

Redressing the blades:
We recommend using a
Johnny's 7229 Work Sharp Tool and Knife
Sharpener
to redress the blade. We specifically added this product to our offering just for this
purpose.
a.
Place harvester on a work bench with the
blade hanging over the edge.
b.
Install a grey fine grit belt on the
sharpener and rotate the head all the way
clockwise as viewed from the side so that
the top pulley is pointing forward as
shown below.
Stop!
Remove battery from drill and
don a pair of gloves.
Cut-resistant
butcher’s gloves are best, but if
unavailable heavy leather work gloves are
recommended.
Don safety glasses also.
c.
Approach the blade with the sharpener as
shown above. When sharpening, hold the
sharpener at a slight angle so that you are
contacting the blade with only a portion of
the belt. This will help prevent rounding off
the points on the serrated blade. rotary
tool or drill so that the grinding stone is at
a similar angle as the bevel in the scallops
of the blade. Sharpen each scallop in the
blade individually - just a couple seconds
each should be enough in most cases.
d.
Turn the harvester over and repeat for the
opposite side of the blade.
