Farm Star HK-203 - Manual (Page 8)

7 4
The Model HK-203 hitch adapter kit is designed for the
John Deere Model A, B, G, 50, 60, and 70 tractors.
This kit uses the existing hydraulic lift on the tractor to
raise and lower the 3-pt. hitch.
NOTE: This kit will fit and work on John Deere Model 70
tractors. However, it is NOT capable of handling all the
power that a Model 70 tractor has. If you install this kit on
a Model 70 tractor and use it for chores and cultivation,
etc., it will do a lot of work for you. It is NOT designed to
pull a 4 bottom plow in heavy soil.
Be sure your tractor is in good condition and properly
equipped with counterweights. Read all the safety
precautions and make sure all tractor operators are
familiar with the safety rules of tractor operation.

Be sure tires and rims are in good condition. Inflate tires
to the proper recommended air pressure.
Check the tractor’s hydraulic system. Refer to your
tractor operator’s manual or dealer for any adjustments
necessary to put the hydraulic system in good working
order. (I&T shop manuals will list most specifications and
adjustment instructions – available from most farm
equipment dealers.)
Check the shield over the PTO stub shaft. Make sure it
is in good condition and bolted securely to the tractor.
Purchase a new shield if old shield is damaged or
missing. (You may have to use a tractor salvage yard for
replacement parts on older tractors.)
It is recommended that a ROPS (Roll-Over Protection
Structure) be installed on all tractors. Contact your local
dealer for ROPS for your tractor.
Check the threaded holes that go into the rear tractor
housing and make sure the threads are in good condition
and that the holes are clean.
NOTE: These holes on the sides of the differential hous-
ing may have painted cork plugs in them. It is necessary
to remove the cork and clean the holes.
If an air hose is used to blow any loose rust or dirt
from the holes, be sure safety glasses are used to
prevent particles from entering an eye.

The HK-203 kit is designed to lift up to 1600 pounds.
This capacity of lift is calculated at a point 24” to the rear
of the lift arms. The lifting capacity is dependent on the
pressure and condition of the tractor’s hydraulic system.
The tractor model and size will also determine the load
that can be safely handled (see page 6). You will also find
that the closer the load is kept to the tractor, the more
you will be able to lift. The tractor and the hitch may be
damaged if you use heavier loads.

The three point hitch kit is shipped as 4 cartons.

For instruction reference, the terms front or rear are
based on the operator facing forward on the tractor, thus
front is toward the front of the tractor and the rear is to
the rear of the tractor.
It is suggested that all the instructions be read before
beginning assembly.
Check the exploded view of the HK-203 hitch kit in this
manual to get an idea of the relationship between the parts.
To mount this kit, it is best to remove the swinging
drawbar from the tractor.
The left-hand and right-hand pull brackets (ref. #7)
attach to the existing swinging drawbar bracket on the
tractor. Bolt the two side bolts (
5 / 8 ” x 2”) first. (Some John
Deere drawbar brackets have two [2] holes on the side –
some have three [3] holes.) In either case, use the two
(2) holes nearest you or to the rear – away from the trac-
tor. Use flat washers over the slotted holes. Leave these
side bolts loose for the time being.
Now bolt the top of the two (2) pull brackets to the top
of the John Deere drawbar bracket – at the same time
bolting on the center link angle brace bracket.
NOTICE: On old style John Deere tractors (Model A,
before serial No. 561903; Model B, before the serial No.
186134; and Model G, before the serial No. 18700) the
drawbar assembly is different, which requires a later
model drawbar support bracket to be installed on your
tractor.
For Model A:
Drawbar support bracket #AA 3843R
Swinging drawbar #A 4822R
Drawbar pivot pin #A 2510R
For Model B:
Drawbar support bracket #AB 3507R
Swinging drawbar #B 3262R
Drawbar pivot pin #AA 5365R
For Model G:
Drawbar support bracket #AF 904R
Swinging drawbar #F 1344R
Drawbar pivot pin #AF 3759R
These parts may be ordered from your John Deere
dealer or from a used parts salvage yard.
When using a 3 pt. hitch rear blade in a reverse
position (bulldozing), use extra care. DO NOT RAM
BLADE into dirt or packed snow piles! Tractor lift
arms and the blade are not built to take high impact
loads in this position. RAMMING backwards can also
dislodge operator from seat and/or tractor controls,
resulting in possible serious injury or death.
Always ease the tractor into the load. It may be
necessary to reposition and take less “bite” on the
material to move it safely.
Watch for and avoid hidden obstructions, i.e.,
buried pipes, rocks, concrete piers, uneven con-
crete slabs, stumps, etc., when operating. This is
especially of concern when removing snow.
C A U T I O N !
Be sure your tractor is in good condition and
properly equipped with counterweights. Read all the
safety precautions and make sure all tractor
operations are familiar with the safety rules of tractor
operation.

Inspect the hitch kit for loose, damaged or worn parts
and adjust or replace if needed.
Repaint parts where paint is worn or scratched to pre-
vent rust.
Check all bolts and nuts to be sure they are tight.
Periodically oil the following:
a. Top link (upper 3rd link) threads
b. Ball sockets
c. Leveling assembly threads
d. Stabilizer bar threads

• Never store equipment with fuel in the tank inside a
building where fumes may reach an open flame or
spark. Allow engine to cool before storing in an
enclosure.
• Do not run engine indoors - exhaust gases contain
carbon monoxide, an odorless and deadly poison.
• Sand areas where paint is chipped or worn and
repaint to prevent rust. Lubricate all pivot locations on
hitch kit to prevent moisture damage during storage.
The adjustable screw type top link can also be short-
ened or lengthened to adapt different implements and
can be used to obtain various degrees of pitch on the
implements you are using.
The ball sockets on the lift arms are two-way balls, so
they will accommodate both Category I or Category II lift
pins on the implement. If the drawbar or implement has
Category I (
7 / 8 ”) pins, make sure the balls are turned so
that the 7 / 8 ” diameter holes are used.
The stabilizer bars should be used whenever possible,
as they not only prevent side sway, but provide rigidity
and stability to the unit – plus added strength. The stabi-
lizer bars are threaded stubs so their length can be
adjusted so the spread of the lift arms can be increased
or decreased to accommodate the different width of
Category I and Category II tools.
NOTE: If the larger 1 1 / 8 ” diameter holes are used with the
smaller 7 / 8 ” pins, the ball sockets will “hole out,” for which
Worksaver cannot be responsible. If you do use smaller
7 / 8 ” diameter lift pins and the larger 1 1 / 8 ” diameter ball
holes, be sure to use lift arm adapter bushings to elimi-
nate the excess play or loose fit.

C A U T I O N !
When traveling on public roads, whether at night or
during the day, use accessory light and devices for
adequate warnings to operators of other vehicles.
Comply with all federal, state and local laws.
Carry load low.
Check visibility. If visibility is impaired, reduce speed or
consider other means of bale transport.
Allow for additional length of loader on tractor while
turning.
Select a safe ground travel speed when transporting
from one area to another. When traveling on roadways,
transport in such a way that faster moving vehicles may
pass you safely.
When traveling over rough or hilly terrain or when
making turns, slow down and use extra care.
Read all the safety warnings in the front of the manual.
