INSTRUCTIONS (continued) SAFETY INSTRUCTIONS (continued)
This equipment is dangerous to children and persons unfamiliar with its operation. The operator should be a
responsible adult familiar with farm machinery and trained in this equipment’s operations. Do not allow
persons to operate or assemble this unit until they have read this manual and have developed a
thorough understanding of the safety precautions and of how it works.
Always load rear of tractor first and unload last when using a front loader.
Use extreme care and maintain minimum ground speed when transporting on hillside, over rough ground and
when operating close to ditches or fences. Be careful when turning sharp corners.
Do not operate close to ditches or creeks. Slow down when operating over rough ground.
Know your controls and how to stop tractor and engine 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,
loader, attachment, and all controls.
Never exceed the limits of a piece of machinery. If its ability to do a job, or to do so safely, is in question -
DON’T TRY IT.
Carry the load slowly and as low as possible to the ground.
Periodically tighten all bolts, nuts and screws and check that all cotter pins are properly installed to ensure unit
is in a safe condition.
Only use a tractor equipped with a ROPS cab or roll-over protective structure.
Know your controls and how to stop tractor, engine, and implement quickly in an emergency. Read this manual
and the one provided with your tractor.
Use particular care when working on inclines and hillsides.
Avoid excessive speed during operation.
Openings in the skin and minor cuts are susceptible to infection from hydraulic fluid. If injured by escaping
hydraulic fluid, see a doctor at once. Gangrene and death can result. Without immediate medical treatment,
serious infection and reactions can occur.
Do not modify the equipment in any way. Unauthorized modification may impair the function and/or safety and
could affect the life of the equipment.
Always shut off tractor and shift to “Park” or set brakes when leaving tractor. Always lower implement to
ground. Remove key when leaving tractor unattended.
Before operating equipment: if you have any questions regarding the proper assembly or operation, contact
your dealer or representative.
ASSEMBLY
It is suggested that all the instructions be read before
beginning assembly.
Check the exploded view of the HHU-2045 in this
manual to get an idea of the relationship of the parts.
Install the lift pins (Part No. 590078) into the pull
brackets on the main frame. For Category I tractors, the
pins go to the inside – for Category II tractors, the pins go
to the outside of the brackets.
Connect the main frame assembly to the 3 pt. hitch of
your tractor. Adjust the top link so that the main frame is
near level and raise the hitch until the main frame is
about 12” above the ground. Block the main frame with
suitable blocking for safety.
The clamp arms are reversible to allow the Model
HHU-2045 to handle a wide range of bale widths. (See
Figure A.)
Assembling the clamp arms to the outside will provide
a handling range for bales 52” to 62” in width.
Assembling the arms to the inside allows the handling of
narrower width bales, from 42” to 52”.
NOTE: The bolts should be inserted with the head of the
bolt against the welded tab on the clamp arm. This
welded tab ensures that the bolt moves with the arm,
which distributes the load over the entire bushing and
bolt surface. This installation will result in one bolt head
up and the other down.
NOTE: It is recommended that a layer of grease be
applied to the 1
1
/
4
” bolt and the top and bottom surface of
the main frame prior to assembly. This provides good ini-
tial lubrication to the pivot.
Tighten the 1
1
/
4
” nuts until the looseness is gone from
the clamp arm, but not so tight that the clamp arm won’t
swing easily.
Insert a cylinder pivot arm through the upside down “U”
shaped bracket with the
3
/
4
” diameter hole forward. Install
a
3
/
4
” x 2” bolt through the
3
/
4
” hole in the pivot arm and
the tab on the front of the main frame. Install a
3
/
4
” nylock
locking nut and tighten until the looseness is gone, but
the arm can still move side to side within the “U” bracket.
Repeat this on the other side.
Place one of the push arms on top of the front plates of
the clamp arms and install the
3
/
4
” x 2” bolt with the nylock
nut and tighten as described previously. Repeat this
procedure on the other side.
Place the spike spinner assemblies into the horizontal
sockets on each end of the clamp arms and secure with
the thrust washers and
1
/
4
” x 2
1
/
2
” cotter pin.
Lubricate with grease before using.
Place your hydraulic cylinder with the hydraulic ports on
top into position at the center of the main frame. Connect
each end of the hydraulic cylinder with the 1” cylinder
clevis pins to both the push arm and the cylinder pivot
arm (both arm ends are in cylinder clevis).
NOTE: Use a 2” x 8” or a 2
1
/
2
” x 8” double-acting
hydraulic cylinder. A 3” x 8” cylinder may be used only if
the tractor’s hydraulic system is set for 1500 psi or less.
DO NOT USE A HYDRAULIC
CYLINDER LARGER THAN 3”
DIAMETER.
Connect your hydraulic hoses to the hydraulic cylinder
and to the remote hydraulic ports on the tractor. Make
sure hydraulic hoses are routed so they will not be
pinched by movement of the Hay Handler/Unroller or any
parts of the 3 pt. linkage.
Start the tractor and raise the Hay Handler/Unroller and
remove the blocking placed during assembly. Grease the
clamp arm pivots and the spike spinner sockets at the
end of the clamp arms.
Cycle the hydraulic cylinder several times to remove air
from the cylinder and lines. Make sure area is clear, as
clamp arms will swing out.
The operator is responsible for the safe operation of this
equipment. The operator must be properly trained.
Operators should be familiar with the tractor, loader and
loader attachment, and all safety practices before start-
ing operation. Read the safety rules.
