SAFETY
YOU are responsible for the SAFE operation and
maintenance of your Harriston Cultivator YOU
must ensure that you and anyone else who is
going to operate, maintain, or work around the
Cultivator be familiar with the operating and
maintenance procedures and related SAFETY
information contained in this manual. This
manual will take you step-by-step through your
working day and alerts you to all good safety
practices that should be adhered to while
operating the Cultivator.
Remember, YOU are the key to safety. Good
safety practices not only protect you but also the
people around you. Make these practices a
working part of your safety program. Be certain
that EVERYONE operating this equipment is
familiar with the recommended operating and
maintenance procedures and follows all the
safety precautions. Most accidents can be
prevented. Do not risk injury by ignoring good
safety practices.
Cultivator owners must give operating
instructions to operators or employees before
allowing them to operate the Cultivator, and at
least annually thereafter per OSHA
(Occupational Safety and Health Administration)
regulation 1928.57.
The most important safety device on this
equipment is a SAFE operator. It is the
operator's responsibility to read and understand
ALL safety and operating instructions in the
manual and to follow them. All accidents can be
avoided.
A person who has not read and understood
all operating and safety instructions is not
qualified to operate the machine. An untrained
operator exposes himself and bystanders to
possible serious injury or death.
Do not modify the equipment in any way.
Unauthorized modification may impair the
function and/or safety and could affect the life of
the equipment.
Think SAFETY! Work SAFELY!

high for ease in assembly. Assembly should
be carried out in a flat and open area.
3.2 MARKING TOOLBAR
Find the center of the tool bar and mark it.
Mark off row spacing on both sides of center
mark. For example, if you are setting up a
cultivator for 30” rows, mark off every 30” on
both sides of center mark.
3.3 REFLECTORS
Place red reflector toward the outside edge
of the tool bar facing the rear and the yellow
reflector toward outside edge facing
forward.

3.5 GANG ASSEMBLY
Clamp the tine mounting tubes to the gang
frame with plates, 7/16” X 3 ½” carriage
bolts, lock washers and nuts. Place the 16”
tubes in the front and 12” tubes in the rear
of gang as shown. The two end gangs will
have two tubes as shown. End gangs will
use plates with 4 holes instead of the six
hole plates.
Mount the gang gauge wheel to the gang
frame. Screw the Adjusting crank all the
way down through the gang frame. Place
one ½” flat washer on top of the gauge
wheel bushing, turn the crank until it
protrudes through the bushing enough to
put another ½” Flat washer & the 3/16” x
3/4” roll pin. Adjust to correct height and
lock with Safety Pin. (See diagram below).
Attach the lower linkage to the gang frame
and front mount with linkage pins and ¼” X
½” roll pins. Insert the upper linkage
between the gang uprights and front mount,
securing with bolts and locknuts.
Attach each gang assembly to the toolbar,
using u-bolts, lock washers and nuts to
mount. Center gang assemblies over the
marks on the tool bar.
Mount the Vertical S-Tines to the front tubes
and on chisel cleaner (if equipped). Use C-
shaped clamps, ½” X 4” hex head bolts,
lock washers and nuts. Mount the regular S-
Tines to the middle tubes with L-shaped
clamps, ½” X 4” carriage bolts, lock washers
and nuts. The two end gangs are to have 3
tines and all of the other gangs get 5 tines.
Fasten shovels to tines using bolts supplied
with shovels.

u-bolts. Center in row with assembly
mounted on front of toolbar
4.3 CHISEL MARKER
The chisel marker mounts on your seeder or
planter. Use u-bolts to mount. Mount
between the two outer rows of your planter
or seeder. Chisel marker slides up and down,
adjust to desired height and lock in place with
set screw.
4.4 CHISEL MARKER CLEANER
A chisel marker cleaner is available for your
cultivator. Bolt the cleaner bracket to the
rear of the gang and mount the tine to the
cleaner bracket.

4.5 HILLER DISCS
The hiller discs are attached to rear of
cultivator gang with hiller mount. Shank and
disc assembly mount to hiller mount with
hiller clamp. Adjust to fit row width.
4.6 SPIDER SHANKS
The spider shanks are attached to rear of
cultivator gang with hiller mount. Shank and
spider assembly mount to hiller mount with
hiller clamp. Adjust to fit row width.
4.6 HILLER DISC SCRAPER
The hiller disc scraper is mounted to the hiller
clamp. A spring between the arms keeps the
blade tight against the disc. Adjust arms for
appropriate pressure when adjusting row
spacing.

14
5 OPERATION & SERVICE
5.1 ADJUSTMENT & OPERATION
Check gangs for movement. They should
move up and down freely but the bolts on the
parallel bars should be tight enough to
eliminate excessive side sway.
Adjust the tines on the gangs to give the
coverage desired.
When entering the field, straddle the rows in
the same direction that planter was used.
Level the cultivator with the top 3-point link
on tractor.
Check gang-working depth. If working depth
is not suitable, adjust gauge wheels on
gangs to the desired depth. Be sure all gangs
are adjusted to the same depth.
Raise the tool bar with tractor 3 point to
where parallel linkage of gangs has 5 to 20
degrees of incline when cultivating. Set
tractor 3-point control to ensure future proper
working position.
Maintain a speed of at least 4 MPH when
cultivating. Slower speeds will limit the
vibrating action of the tines and reduce their
effectiveness.
Set the hiller discs shallower than the S-
Tines so the discs are working with loose dirt.
The discs can be adjusted by loosening the
clamp bolts and turning the discs for desired
hill.
5.2 MAINTENANCE
Check all nuts and bolts for tightness.
Clean off dirt that has accumulated on
moving parts to prevent abrasion that will
cause faster wear.
Grease all fittings.
5.3 STORAGE
When through with the cultivator for the year,
clean away all trash and dirt, which could
hold moisture and cause rusting.
Look for worn or broken parts on the
cultivator. Order these from your Harriston
Dealer during the off-season so that they can
be replaced and the cultivator will be ready
when needed next year.
