Fast, effortless harvesting for the
small-scale grower. No more kneeling,
no more knives or scissors. One person
can easily cut over 175 lb. per hour.
Powered by a cordless drill, the
harvester's 15" serrated blade makes a
smooth, clean cut. A rolling macramé
brush pulls individual leaves into the
blades and then throws them to the back
of the basket. This unique design allows
the Quick Cut to harvest sparse stands of
salad ingredients as effortlessly as it
harvests full stands. The neat, clean
surface it leaves behind is perfect for
those planning on a second harvest from
the same bed. The harvester is just as
effective when the crop is more mature or
"leggy." Universal mount will accept
almost any cordless drill; 18 or 20V drills
work best (not included). Weighs 6.5 lb.
without a drill. Add another 3-5 lb.,
depending upon your drill. Made in USA.

ASSEMBLY:
Take care when removing from
packaging, in case blade guard
has come off in transit.
1. Remove harvester and other
contents from packaging. Loose
contents should include food grade
lubricant, drill support arm with
velcro strap, two backing plates,
and six flat head screws.
2. Attach basket to frame:
a. Left side:
i. Insert end of basket frame
arm (R) into its mounting
channel (U) on the left frame
upright (P).
ii. Cover with small backing plate and secure with two mounting screws.
iii. Remove small screw and washer near the backing plate mounting screws, and secure the
corner of the harvester basket to the left upright with them.
b. Right side:
i. Insert end of basket support arm (S) into mounting channel (V) on the right frame upright
(P).
ii. Insert the end of drill support arm (M) into mounting channel (V) on the right frame upright
(P).
iii. Cover with large backing plate and secure with four mounting screws.

3. Adapt drill to the harvester:
a. Carefully remove tape and guard from blade.
b. Insert battery into drill. Set drill clutch to maximum torque
(or as indicated on some models the “drill bit” position –
see below). Set drill speed to maximum setting. Open
chuck fully, then shift back to clockwise.
c. Slide cordless drill chuck over top of drive shaft as
shown below. There should be at least ¾” of drive shaft
inside the chuck, otherwise slippage could occur.
Stop! You are about to engage the drive of this machine. Ensure that the blade is free of
obstruction and that it is not near you or anyone else.
d. Grasp the keyless chuck with your left hand, and slowly squeeze
the trigger until the drill starts to turn and the chuck makes
contact with the drive shaft (H) . As it does so, the macramé
roller (B) should start to turn and the blade will begin to
reciprocate back and forth. Firmly grip the chuck and hit the
trigger again to seat the chuck securely onto the drive shaft. Be
careful not to pinch your fingers between the chuck and the
harvester frame.
e. Back the clutch off to 1/2 of its max setting. This should allow
adequate operating torque and jam protection for the harvester.
f. Hold the battery end of the drill against the drill support arm (M)
and wrap the velcro strap around them as shown to the right.
This merely keeps the drill stationary when the harvester is
transported.
Stop! Remove battery from drill.

OPERATION:
1. Basic single cut operation:
a. Position harvester at the end
of the bed
b. Insert battery in drill.
Stop! You are about to
engage the drive of this
machine. Ensure that the
blade is free of
obstruction and that it is
not near you or anyone
else.
c. Squeeze the trigger fully and
glide the harvester into and
through the crop,
maintaining the desired
cutting height.
d. It may be necessary every
so often, especially with
taller crops, to pause and
flip any cut greens bunched
up behind the roller to the
back of the basket.
e. Reposition
where you
left off and
begin again.
f. When full,
empty basket
contents into
a harvest tote
by holding
the end of the
basket
closest the
operator over
the tote
vertically, and
shaking it
slightly.
g. Return to
step 2.e. and
continue
harvesting.

2. “Cut-and-come-again”
operation: For this, a very level,
even cut is desirable, so that in
subsequent cuts, you are able to
cut just above the previous pass
in order to harvest only new
growth from the crop. Re-growth
in cut-and-come-again plots is
typically much less dense than
the original growth. The Quick
Cut Greens Harvester allows
harvesting even sparse stands
because the unique macramé
roller draws any standing leaves
it encounters into the blade for a
quick, clean cut.
3. Taller or “Leggy” crops: It may
be desirable to cut at a
considerable height above soil
level and leave behind leggy
petioles. You will also find it
difficult to cut anything taller than
the distance between the cutter
bar and the shaft of the
macramé roller. For this reason,
if you desire to do so, you may
need to cut just the top portions
of the leaves of more mature
stands. Simply maintain the
desired cutting height evenly
across the crop, leaving behind
the unwanted stems.
4. Keep it sharp! It is critical for
proper operation of this product
that the blades be maintained
and sharpened often. Refer to
the MAINTENANCE section for
in-field sharpening and periodic
redressing of blades.

MAINTENANCE: This tool is a fine cutting instrument with many moving parts. The
better it is cared for, the better it will continue to perform in the field. Periodic cleaning
and sharpening as well as careful storage are crucial to keeping it in working order and
ready when you need it.
1. Lubrication: For convenience we have
included a small amount of food grade
lubricant with your harvester. The blade
should be lubricated before first use and
periodically thereafter. We would suggest
lubricating it every time you re-dress (not
field sharpen) the blade. An MSDS sheet
for the lubricant is attached to these
instructions for your information.
Stop! Ensure that the blade guard is
installed before you proceed.
a. Remove the blade
guide pin and pivot
the blade forward.
This will leave the
blade guide slot
accessible for
oiling.
b. Slide the tip of the
lubrication bottle
along the slot and
squeeze the bottle
slightly to drizzle oil
into it. Also oil the
blade slide bearing
(C) at the right end
of the blade.
c. Re-install the blade
and guide pin. Use
a rag to wipe off
any excess oil.

2. 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.
a. Turn the harvester on its left side (the side without
the drill).
b. Using a Johnny's 9175 Round Diamond Hone,
“strop” the hone back and forth across the top blade;
do not attempt to sharpen individual scallops.
c. Repeat for the opposite side.
3. 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.

4. Post harvest cleaning:
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.
a. Remove blade guard if installed.
b. A damp rag may be enough to
clean your harvester. If not, set
your hose nozzle at “Jet” or similar
highest pressure setting, and hose
off the lower assembly and basket,
removing any soil and remaining
crop material from the harvester.
c. If crop material or juice has been
allowed to dry on the blades or
material, you can use a stiff bristle
brush and a wash solution of water
and liquid dish detergent to clean
the harvester more thoroughly. A
long handled brush is ideal as it
keeps hands further from the
blade.
d. Place guard back over blade.
5. Storage: It is extremely important
that you store your harvester in a
safe spot to prevent inadvertent
damage and accidental injury.
a. Remove drill.
b. Place guard over blade.
c. Hang in a secure, dry location
with the blade facing the wall.
