CAUTION
THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE THOROUGHLY UNDERSTOOD
BEFORE ATTEMPTING TO BEGIN ASSEMBLING THIS MACHINE.
1. Select an area for assembly that is clean and free
of any debris, which might cause persons
working on the assembly to trip.
2. Do not lift heavy parts or assemblies. Use crane,
jack, tackle, fork trucks or other mechanical
devices.
3. Preview the assembly instructions in your
operator’s manual before proceeding further.
4. If the assembly instructions call for parts or
assemblies to be blocked up, use only blocking
material that is in good condition and is capable
of handling the weight of the assembly to be
blocked. Also insure that the blocking material is
on a clean, dry surface.
6. After completing assembly, thoroughly inspect
the machine to be sure that all nuts, bolts,
hydraulic fittings or any other fastened
assemblies have been thoroughly tightened.
7. Before operating the machine, thoroughly read
the operation section of your operator’s
manual.
8. Before operation, read the maintenance section
of your operator’s manual to be sure that any
parts requiring lubrication such as gearboxes
are full to avoid any possible damage.
9. Before operating equipment. If you have
any questions regarding the proper
assembly or operation, contact your
Worksaver dealer or representative.
5. Never put hands, or any other part of body under
blocked up assemblies if at all possible.

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.
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.
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.
NOTE: The top link should be placed at the
approximate center of the tractor rocker shaft.
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.
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 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
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.
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
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.
üKeep children away from danger all day,
every day.
üEquip tractors with rollover protection
(ROPS) and keep all machinery guards
in place.
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
üPlease work, drive, play, and live each
day with care and concern for your
safety and that of your family and fellow
Category II tools.

SAFETY PRECAUTIONS
MOST ACCIDENTS OCCUR BECAUSE OF NEGLECT OR CARELESSNESS, AVOID NEEDLESS
ACCIDENTS BY FOLLOWING ALL OF THE SAFETY PRECAUTIONS LISTED BELOW.
·
·
Machinery should be operated only by those
who are responsible and are authorized to do so.
Stop the engine, lower all equipment, lock the
brakes, and remove the ignition key before
dismounting from the tractor.
Never stand between tractor and implement
while tractor is being backed to hitch.
Loose fitting clothing should not be worn, to
avoid catching on various parts.
·
A heavy load can cause instability of the
tractor. Use extreme care during road travel.
Slow down on turns and watch out for bumps.
Tractor may need front counter-weights to
counter-balance the weight of the implement.
Reduce speed on hillsides or curves so there is
no danger of tipping.
·
·
·
·
·
·
·
Avoid driving too close to the edge of ditches
or creeks.
Do not transport implement on public toads
without reflectors and slow moving vehicle
emblem in daylight and with approved
warning lights at night and other periods of
poor visibility.
Due to the width of some implements, use
extra caution on highways, farm roads, and
when approaching gates.
Detach implement in area where children
normally do not play.
When performing adjustments or maintenance
on an implement, first lower it to the ground or
block it securely at a workable height.
Only a qualified operator should be permitted
on tractor when in operation; no riders allowed.
Make certain everyone is in the clear before
starting tractor or raising or lowering
equipment.
Operate the tractor and implement only while
seated in the driver’s seat.
