If you tractor is equipped with a belly mower, it will be
necessary to remove it, the drawbar, and V-belt pulley
that is attached to the PTO, in order to install this kit.
NOTE: It is recommended that the belly mower and V-
belt pulley on the PTO shaft be removed for easier hitch
installation. However, once the hitch is installed, the hitch
can be left on the tractor with most belly mowers. It is
necessary to remove the cross stabilizer bar when using
a belly type mower.
Check the threaded holes that go into the tractor wheel
housing and make sure the threads are in good condition
and that the holes are clean.

The Model HK-90 hitch adapter kit is designed for the
Farmall and International (I.H.C.) standard model Cub
tractor (built between 1947 and 1979). The tractor must
have a hydraulic system
The Model HK-91 hitch adapter kit is designed for the
I.H.C. model Cub Lo-Boy built between 1955 and 1968.
This kit is NOT for the International Cub 154 Lo-Boy, the
International Model 184, or the International Cub Model
185 Lo-Boy.
Both of these hitch adapter kits use the existing
hydraulic lift on the tractor to raise and lower the 3 pt.
hitch.
These hitch kits are designed to allow the tractor to
handle implements or loads that do not exceed 350 lbs.
at a point 24 inches to the rear of the lift arms. The trac-
tor and the hitch may be damaged if you handle heavier
loads.
NOTE: The Cub and Cub Lo-Boy are lightweight tractors
and the front end of the tractor will be lighter when a load
is picked up with a 3 pt. hitch.

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 hitch kits in this manual
to get an idea of the relationship between the parts.

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.

Check the tractor over to make sure it is in good work-
ing condition. Check all bolts and make sure they are
tight.
Check hydraulic system for operation and oil level.
Be sure tires and rims are in good condition. Inflate
tires to the proper recommended air pressure.
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.

The adapter kit is shipped in knocked down conditions
so as to command the lowest freight rates. Shipment
consists of 2 cartons.
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.
C A U T I O N !
Read manual before operating.
C A U T I O N !
Before installing the adapter kit on the tractor,
locate the tractor on a level surface, engage the park-
ing brake, shut off the tractor and remove the key.
C A U T I O N !
ALWAYS OBEY ALL SAFETY RULES!
ALWAYS BE CAREFUL!
M A I N T E N A N C E
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
prevent 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
REPLACE SAFETY SIGNS
IF DAMAGED OR MISSING!
When completing a maintenance or service function,
make sure all safety shields and devices are installed
before placing unit in service.

• 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.
W A R N I N G !
▲ Keep clear of rotating parts; stay on tractor seat
until all motion has stopped.
▲ Be sure tractor engine is off and key is removed
before making any adjustments.
▲ Do not get under machine to make measurements
or adjustments without securely blocking imple-
ment first.
ALWAYS OBEY ALL SAFETY RULES! ALWAYS BE CAREFUL!
O P E R AT I O N
Make sure all operators have read all the safety
warnings and precautions in this manual and those in the
tractor operator’s manual.
Be sure tractor is properly counterbalanced with
weights before attempting to lift any load.
Position the implement behind the tractor, slide the lift
arm ball ends on the implement pull pins and lock in
place with
7 / 16 ” linch pins.
Attach the toplink to the implement toplink bracket using
a 3 / 4 ” toplink pin and linch pin (not provided).
Use the screw adjustment to level the R.H. lift arm with
L.H. arm or to provide the proper “pitch” for mounted
plows. The adjustable screw type leveling assemblies
will provide adjustment in the lifting height of the hitch.
NOTE: BE SURE THAT AT LEAST 1
1 / 4 ” OF THREAD
ON EACH END IN ENGAGED INTO THE THREADED
BARREL OF THE LEVELING ASSEMBLIES.
Adjust the top link assembly to level the implement fore
and aft. 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.
This kit is designed to lift up to 350 lbs., but, of course,
lifting capacity is dependent on the pressure and condi-
tion of the tractor’s hydraulic system. You will also find
that the closer the load is kept to the tractor, the more
you will be able to lift.
NOTE: Use of Stabilizer Bars
Some implements such as post hole diggers, rear
blades, landscape rakes, and rear 3 pt. scoops, you will
need to install the stabilizer bars to eliminate side
movement of the hitch to control the implement.
With other implements, such as 3 pt. plows, disc
harrows, field cultivators, and harrows, it is best to
remove the stabilizer bars and allow the hitch side
movement. This makes it easier to steer the tractor and
minimize side pressure on the hitch and the implement
when turning.
