Farm Star HK-16782 - Manual (Page 2)

To the Owner/Operator/Dealer
All implements with moving parts are potentially hazardous. There is no substitute for a cautious, safe-minded operator who
recognizes the potential hazards and follows reasonable safety practices. The manufacturer has designed this implement to be used
with all its safety equipment properly attached, to minimize the chance of accidents.
BEFORE YOU START!! Read the safety messages on the implement and shown in your manual. Observe the rules of safety
and common sense!
Instructions
The Model HK-1678 and HK-16782 hitch adapter kit
is designed for a variety of tractor models manufactured
by Oliver Corporation. Either kit can be used on any of
the tractor models.
The Model HK-1678 uses one hydraulic cylinder and
is designed for the small to medium size tractor models
(66, Super 66, 660, 77, Super 77, 770).
The Model HK-16782 uses two hydraulic cylinders
and is designed for the medium to larger size tractor
models (77, Super 77, 770, 88, Super 88, 880). The two
hydraulic cylinders provide a greater lift capacity than the
one cylinder model.
PACKING
The adapter kit is shipped in knocked down condition
so as to command the lowest freight rates. Shipment
consists of 1 Bundle, 1 Carton.
TRACTOR PREPARATION
Before installing the adapter kit, it is necessary to
remove the existing swinging drawbar assembly.
Check the threaded holes that go into the tractor
housing and make sure the threads are in good condition
and that the holes are clean.
CAUTION! 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.
Be sure tires and rims are in good condition. Inflate
tires to the proper recommended air pressure.
Check the tractor’s hydraulic system. Refer to your
tractor operator’s manual or dealer for any adjustments
necessary to put the hydraulic system in good working
order. (I&T shop manuals will list most specifications
and adjustment instructions – available from most farm
equipment dealers.)
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 a ROPS for your tractor.
ASSEMBLY
When the existing drawbar assembly has been
removed, bolt the mainframe assembly in place using
the same holes as the tractor drawbar assembly. 5/8” x
1-3/4” hex head bolts are provided for the upper holes,
and ¾” x 2” hex head bolts are provided for the lower
holes.
The 3” x 8” hydraulic cylinder (not supplied) should
be attached at this time; it will keep the rockershaft in
place so that the remainder of the kit may be
assembled. The barrel end of the cylinder attaches to
the lower lug on the main frame using your cylinder
pin. The piston end of the cylinder attaches to the
cylinder arm that swings down from the rocker shaft.
Using your cylinder pin, attach the piston end of the
cylinder to the cylinder arm (Ref. #2); this gives you a
floating hitch.
Pin the leveling assemblies to the rocker shaft lift
arms (arms with balls welded on), using the 7/8” flat
head pins and linchpins.
Place the lift arms between the lower clevises on the
leveling assemblies and pin in place with the ¾” lower
lift pins.
Install the stabilizer stub pins (Ref #17) 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 lock
washer 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 #20) over
the ends of the pull pins on the outer ends of the frame
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: When connection 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
¾” top link pin and linchpin provided.
