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  
citizens.

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.
