Attach the two lift control arms (slotted end goes to the
hitch main frame) to the hydraulic lift quadrant on the
tractor. Using one of the
5 / 8 ” – 11 x 2 1 / 4 ” hex head bolts,
2 flat washers, and locknut, attach the other end to the
upright arm on the main frame (arm without ball
socket). Use the slot so that the hitch will float as the
tractor navigates rough terrain. Be sure to use a flat
washer against the slot. Check to see that the lift
control arm moves freely but without excessive
looseness.
On both the outer left-hand and the right-hand ends of
the pull brackets, start the ends of the pull pins (ref.
#11) 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.
#12) 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 pull bracket 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.
Pin the leveling assemblies (ref. #20-24) to the
rockershaft lift arms (arms with balls welded on), using
the
7 / 8 ” flat head pins (ref. #26) and linchpins.
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. #27) 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 lockwasher
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. #16-19) over
the ends of the pull pins on the outside of the pull
bracket 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.
NOTE: Angle of Stabilizer Ends
The ends of the stabilizer bars (ref. #17, 18) may not be
at the correct angle for your hitch. Since this hitch kit can
connect to either Category I (26” pull pin width) or to
Category II (32” pull pin width) equipment, slightly differ-
ent angles will be required on the stabilizer bar threaded
stub ends. If the angle is not correct for your desired hitch
spacing, place one end of the stabilizer bar threaded
stub in a vise and apply hand pressure to the other end
of the stabilizer bar assembly until desired angle is
obtained. Reverse the stabilizer assembly in the vise and
repeat for the other end.
It is suggested that you connect the lift arm ends to a
piece of equipment or install a 3 pt. drawbar and center
the lift arms (side to side) so you can easily determine
what angle correction may be required.
NOTE: Use of Stabilizer Bars
For some implements such as post hole diggers, rear
blades, landscape rakes, and rear 3 pt. scoops, you
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.
NOTE: When connecting 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 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.
Attach the center link to the main frame using the 3 / 4 ”
toplink pin and linchpin provided.
Tighten all bolts before using this kit.
Check to make sure that the hitch is operating smoothly.
Read manual before operating.
O P E R AT I O N
Two 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 1 1 / 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 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.

• Know your controls and how to stop tractor, engine,
and PTO quickly in an emergency. READ THIS
MANUAL AND THE ONE PROVIDED WITH YOUR
TRACTOR.
• To avoid accident or injury, do not allow anyone to
operate this equipment without proper instructions.
Any person who operates this equipment must be
instructed in and be capable of the safe operation of
the tractor, implement and all controls.
• Do not allow children to operate this machine.
• Always wear relatively tight and belted clothing to
avoid entanglement in moving parts. Wear sturdy,
rough-soled work shoes and protective equipment for
eyes, hands, and hearing. Never operate tractor in
bare feet, sandals, or sneakers.
• Operate only in daylight or good artificial light.
• Ensure implement is properly mounted, adjusted and
in good operating condition.
• Ensure that all safety shielding and safety signs are
properly installed and in good condition.
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.
Figure 1. Tractor Stability
W A R N I N G !
When using 3 pt. hitch equipment, a minimum 20%
of tractor and equipment weight must be on tractor
front wheels. Without this weight, tractor could tip
up, causing possible loss of control and possible
personal injury or death. The weight may be attained
with a front end loader, front wheel weights, ballast
in tires or front tractor weights. When attaining a
minimum 20% of tractor and equipment weight on
the front wheels, you must not exceed the ROPS
weight certification. Weigh the tractor and equip-
ment. DO NOT GUESS OR ESTIMATE!
A heavy load can cause instability in driving a trac-
tor. Make sure the front of the tractor is properly
counter-balanced with weights. Always drive slowly
– especially around turns. An unstable tractor could
steer badly and possibly tip over, causing injury or
death.
