INSTRUCTIONS
CAUTION!
Be sure your tractor and loader is in good condi-
tion. Read all the safety precautions and make sure
all equipment operators are familiar with the safety
rules of operation.
WARNING!
■ Power unit must be equipped with ROPS or ROPS
cab and seat belt. Keep seat belt securely fastened.
Falling off power unit can result in death from being
run over or crushed. Keep foldable ROPS systems in
“locked up” position at all times.
■ Always install the quick lock pins on the John
Deere 300, 400, and 500 series loaders. Failure to
install the lock pins may cause injury or death
caused by falling attachment.
■ Do not exceed the maximum recommended bale
weight listed for each of the loader spear models.
Damage to the equipment or serious personal injury
could result.
■ A heavy load can cause instability in driving a
tractor. Make sure the rear of the tractor is properly
counter-balanced with weights. Always drive slowly
– especially around turns. An unstable tractor could
steer badly and possibly tip over, causing injury or
death.
WARNING!
On double spear models JDBS-423 / JDBS-623,
and three spear models JDBS-434 / JDBS-433 and
JDBS-634 / JDBS-633, always insert spears into the
bale – NEVER under the bale. Failure to insert spears
into bale can allow bale to roll back when loader is
raised, causing serious injury or death.
INTRODUCTION
——————————————————
The integrated-frame bale spears for John Deere trac-
tor loaders are designed to fit two series of John Deere
front loaders.
The models JDBS-412, JDBS-423, JDBS-434 and
JDBS-433 are for the John Deere 300, 400, and 500
series loaders.
The models JDBS-612, JDBS-623, JDBS-634 and
JDBS-633 are for the John Deere 600 and 700 series
loaders.
The maximum recommended weight of bales that can
be handled by the various models of bale spears are as
follows:
Model # Main Spears Bale Weight
JDBS-412 1 2200 Lbs.
JDBS-423 2 3000 Lbs.
JDBS-434 3 4000 Lbs.
JDBS-433 3 3000 Lbs.
JDBS-612 1 2200 Lbs.
JDBS-623 2 3000 Lbs.
JDBS-634 3 4000 Lbs.
JDBS-633 3 3000 Lbs.
Always use a tractor and front loader large enough to
safely handle your bales.
Check your tractor and front loader to make sure they
are in good working condition. Check all loader mounting
bolts to make sure they are tight.
Check the tractor’s hydraulic system. Be sure the
hydraulic oil and filter have been serviced according to
manufacturer’s recommendations. Refer to your tractor or
loader operator’s manual or dealer for any adjustments
necessary to put the hydraulic system in good working
order.
Be sure tires and rims are in good condition. Inflate tires
to the proper recommended air pressure.
TRACTOR AND LOADER
REQUIREMENTS AND
PREPARATION
——————————————————
The required size of the tractor and front loader will be
determined by the size and weight of the bales to be
handled.
Remember, high moisture hay (silage) bales are very
heavy in relation to similar size dry hay bales.
INSTRUCTIONS (continued)
ASSEMBLY
——————————————————
Refer to the “exploded views” on pages 19-27 of this
manual.
Carefully follow instructions for final assembly.
Remove the bucket from your front end loader. Check
your loader to make sure it is in good working order.
Check all frame mounting bolts to make sure they are
tight.
Place the main frame of the bale spear attachement on
the front of the loader.
On the 300, 400, and 500 series loaders, install the lock
pins.
On the 600 and 700 series loaders, make sure the latch
bars are properly engaged.
Raise the loader and main frame slightly so that the
bottom of the main frame is about one or two inches off
the ground. Engage tractor parking brake and shut off the
engine.
Place some solid blocking under the main frame of the
bale spear attachment for safety.
A. On the JDBS-412 / JDBS-612, insert the long,
forged main spear into the socket and align the cross
hole in the spear with the hole in the socket. Install the
1
/
2
” x 3” bolt and tighten the nut.
Place the two short stabilizer spears into the sock-
ets on the bottom of the main frame. Secure with the
5
/
16
”x 1
3
/
4
” bolts provided.
B. On the JDBS-423 / JDBS-434 / JDBS-433 /
JDBS-623 / JDBS-634 and JDBS-633, insert the long,
forged main spears into the sockets in the main frame
and align the cross hole in the spear with the hole in
the socket. Install the
1
/
2
” x 3” bolt and tighten the nut
on each spear.
OPERATION
——————————————————
The operator is responsible for the safe operation of this
equipment. The operator must be properly trained.
Operators should be familiar with the attachment, tractor,
and loader and all safety practices before starting
operation.
Make sure all operators have read the
Owner’s/Operator’s Manual and are familiar with the
instructions and the safety rules of operation.
Be sure tractor is properly counter-balanced with
weights before attempting to lift any load with the Bale
Spear attachment.
If you are handling bales with both the front end loader
and the 3 pt. hitch on the tractor, always load the 3 pt.
attachment first and unload last.
The bale spear is to be used only for handling hay bales.
Do not use for digging rocks, pulling out fence, or as a
craning device with a chain over the spear.
LARGE ROUND BALES:
Using the bucket tilt cylinders, adjust the angle of the
spear(s) so they are parallel with the center of the hay
bale.
With the tractor, push the spear(s) into the large hay
bale. Make sure you have penetrated the hay bale far
enough so the bale doesn’t want to come off the end of
the spear(s). If, when you initially pick the bale up, it tends
to droop forward, this would indicate you have not pene-
trated the bale far enough.
Tilt the ends of the spear(s) upward (about 15-20
degrees) when transporting the hay bales. This will
reduce any tendency for the bale to slide off the spear(s)
while being transported.
When you have placed the hay bale in the desired loca-
tion, it is recommended to tilt the spear ends slightly
downward (5-7 degrees) so as you pull away from the
bale it will slide off the spear(s) more easily. Different
location and circumstances will determine the best with-
draw angle to use.
NOTE: Always make sure bale spear fully penetrates the
bale. Partial penetration locates all the weight of the bale
on the outer end and can damage spear.
