Instructions
(Continued from page 1)
This hitch is designed to utilize your existing swinging
drawbar. The lower attaching frame bolts to the ears
located on the lower cross-angle of the hitch. The upper
attaching bars bolt to the upper horizontal mounting
brackets on the hitch. Two ¾” x 2” bolts, lock washers,
and nuts and two 5/8” x 1-3/4” bolts, lock washers, and
nuts are provided to attach the drawbar to the hitch.
Tighten all bolts before using this kit.
Connect your hoses from the tractor’s hydraulic system
to the hydraulic cylinder on the hitch kit. Check to make
sure that the hoses are located so that they will not be
pinched or chafed by any of the moving parts on the hitch.
Avoid sharp bends with hydraulic hose.
Use a good quality thread sealant on all connections.
DO NOT USE TEFLON TAPE (small pieces of tape can
get into hydraulic valves and components, causing
problems).
Check the hydraulic relief valve setting on the tractor to
make sure it is properly set (ref to tractor specifications by
Oliver).
When the hydraulic system is connected, cycle the
hydraulic cylinder a few times to remove any air bubbles.
Check to make sure that the hitch is operating smoothly.
MAINTENANCE
Check all bolts and nuts to be sure they are tight.
Periodically oil the following:
a. Top link (upper 3 rd link) threads
b. Cylinder pins
c. Ball sockets
d. Leveling assembly threads
e. Stabilizer bar threads
Check hydraulic hoses and fittings – make sure the
hoses are not rubbing or chafing on any of the moving
parts.
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 ball sockets on the lift arms are two-way balls, so
they will accommodate both Category Category II or I 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.
NOTE: If the larger 1-1/8” diameter holes are used with
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 in the larger 1-1/8” diameter
ball holes, be sure to use lift arm adapter bushings to
eliminate the excess play or loose fit.
The stabilizer bars should be used whenever possible, as
they not only prevent side sway but also provide rigidity
and stability to the unit – plus added strength. The
stabilizer 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.
The HK-1678 (single hydraulic cylinder) kit is designed
to handle up to 1500 lbs. The HK-16782 (double hydraulic
cylinder) kit is designed to lift up to 2400 lbs. The lifting
capacity is dependent on the pressure and condition of the
tractor’s hydraulic system. You will also find that the
closer the load is to the tractor, the more you will be able to
lift.
NOTE: The size of the tractor will be the main
determining factor in how much weight you can handle (a
Model 77 can handle more than a Model 66 and a Model
880 can handle more than a Model 77).
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 operating. This is especially of concern when
removing snow.
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.
