To the Owner/Operator/Dealer
All implements with moving parts are potentially hazardous. There is no substitute for a cautious, safe-minded operator who
recognizes the potential hazards and follows reasonable safety practices. The manufacturer has designed this implement to be used
with all its safety equipment properly attached, to minimize the chance of accidents.
BEFORE YOU START!! Read the safety messages on the implement and shown in your manual. Observe the rules of safety
and common sense!
Instructions
The Model HK-307 hitch adapter kit is designed for
the Allis Chalmers Model CA tractors.
This kit uses the existing hydraulic lift on the tractor
to raise and lower the 3-pt. Hitch.
frame braces. Tighten these bolts securely.
Pin the pivoting ends of the lift arm leveling
assemblies to the tractor lift brackets with the 5/8” top
link pins and linchpins provided.
On both the outer left-hand and the right-hand ends
of the hitch main frame, start the ends of the pull pins
(Ref. #5) through the outer pull bracket ears. Position
the pull pin so that the end with NO hole goes to the
inside.
As soon as the end of the pull pin passes through the
first outer pull bracket ear, slide the pull pin spacer
(Ref #6) on the pin so that it is located between the first
and second pull bracket ears. Slide the pull pin in
further until the end is just entering the second pull
bracket ear.
Then place the forward end of the lift arm between
the large side plate on the main hitch frame and the
second pull bracket. Slide the pull pin in further so that
it goes through the ball end of the lift arm and enters
the hole in the large side plate.
Rotate the pull pin so that the holes in the pin are
horizontal. Slide the spacer tube and adjust the pull pin
so that a large (5/16”) hairpin clip can be inserted
through the center hole of the pull pin. This locks the
pull pin in place on each side.
Raise the lift arms, sliding them between the clevis
ends of the lift arm leveling assemblies, and pin them
in place.
Install the stabilizer stub pins (Ref #19) in the
forward holes of each lift arm. Have the large (7/8”)
diameter of the stub pin to the outside of the lift arm
and the threaded nut to the inside. Do not use a lock
washer under the nut. Place a screwdriver or small
bar through the linchpin hole and tighten the nut on the
stub pin.
Place one end of the stabilizer bars (Ref #17) over
the ends of the pull pins on the outer ends of the frame
and secure with linchpins.
The stabilizer bars have threaded ends and can be
adjusted to the correct length by turning the center
barrel. Adjust the stabilizer bars, then slide the other
end over the stabilizer stub pins in the lift arms. Secure
in place with linchpins.
PACKING
The adapter kit is shipped in knocked down condition
so as to command the lowest freight rates. Shipment
consists of 1 cartons and 1 frame assembly.
TRACTOR PREPARATION
Before installing the adapter kit, it is necessary to
remove the existing swinging drawbar assembly.
Check the threaded holes that go into the tractor
housing and make sure the threads are in good condition
and that the holes are clean.
CAUTION! 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.
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 a ROPS for your tractor.
ASSEMBLY
In order to mount this kit, it will first be necessary to
remove the swinging drawbar and mounting brackets
from your tractor. Using the 7/8” x 6-1/2” draw pin,
attach the main frame to support arm on the underside of
the tractor and secure it with the hairclip pin provided.
Slide the mainframe braces over the outside pins
mounted in the rear axle housings in the position shown
on the parts drawing and capture them with the hairpins
provided. Pivot the rear of the main frame to the main
NOTE: When connection the hitch to an implement, it
will be necessary to remove the lift arm end of the
stabilizer bar from the lift arm. This allows the lift arm
to swing out and be installed on the pull pin of the
Page 1

Instructions (Continued from page 1)
implement.
After the lift arms are connected to the implement,
the stabilizer bars need to be reconnected and adjusted
so that the implement is centered behind the tractor.
Remove the top link bracket from the top link and
place it around the rocker shaft of the tractor.
Re-attach the top link to the top link bracket, and
tighten the bolt securely. Place the top link clamps,
one on each side of the top link bracket and tighten
them securely.
NOTE: The top link should be placed at the
approximate center of the tractor rocker shaft.
OPERATION
Two (2) holes are provided on the lift arms to
connect to the lower ends of the leveling assemblies.
The forward holes will provide the greatest lifting
range for the ball ends of the lift arms. The rear holes
will allow heavier loads to be handled by the hitch.
The adjustable screw type leveling assemblies will
provide additional adjustment in the lifting height of
the hitch. NOTE: BE SURE THAT AT LEAST 11/4” OF THREAD ON EACH END IS ENGAGED
INTO THE THREADED BARREL OF THE
LEVELING ASSEMBLIES.
The adjustable screw type top link can also be
shortened or lengthened to adapt different implements
and can be used to obtain various degrees of pitch on
the implements you are using.
The 2-way ball sockets on the end of the lift arms
will allow you to connect to either Category I or
Category II implements. If the drawbar or implement
you mount has Category I (7/8” dia.) pins, then make
sure the balls are turned so that the 7/8” dia., holes are
used.
IMPORTANT: If the larger 1-1/8” dia., holes
are used with the smaller 7/8” dia., pins, the
ball holes will wear rapidly in an uneven
pattern and make the entire ball socket
eventually unusable.
The stabilizer bars should be used whenever
possible, as they provide rigidity and stability to the
unit – plus added strength. The stabilizer bars have
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.
Page 2
This kit is designed to lift up to 1600 lbs., but, of
course, lifting capacity is dependent on the pressure
and condition of the tractors hydraulic system. You
will also find that the closer the load is kept to the
tractor, the more you will be able to lift.
CAUTION! 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.
CAUTION! 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 concrete
slabs, stumps, etc., when operation. This is especially
of concern when removing snow.
MAINTENANCE
Check all bolts and nuts to be sure they are tight.
Periodically oil the following:
a. Top link (upper 3rd link) threads
b. Cylinder pins
c. Ball sockets
d. Leveling assembly threads
e. Stabilizer bar threads
ü Keep children away from danger all day,
every day.
ü Equip tractors with rollover protection
(ROPS) and keep all machinery guards
in place.
ü Please work, drive, play, and live each
day with care and concern for your
safety and that of your family and fellow
citizens.
