WARNING!
MAKE SURE THAT ALL OPERATING AND SERVICE
PERSONNEL KNOW THAT IN THE EVENT
HYDRAULIC FLUID PENETRATES THE SKIN, IT
MUST BE SURGICALLY REMOVED WITHIN A FEW
HOURS BY A DOCTOR FAMILIAR WITH THIS FORM
OF INJURY, OR GANGRENE MAY RESULT.
Refer to Figure F and assemble the
3
/
4
” x 3” pipe nip-
ple (ref. #32), the
3
/
4
” pipe tee (ref. #30), and
3
/
4
” to
1
/
2
”
reducer bushing (ref. #29) to the
3
/
4
” outlet port fitting in
the single spool ram control valve. Then connect a
3
/
8
”
I.D. x 36” long hose (ref. #22) from the reducer bush-
ing (ref. #29) to the
1
/
2
” 90° elbow, (ref. #35) that is
connected to the two spool valve.
Connect the
3
/
8
” I.D. x 216” long hose from the inlet
side of the two spool valve to one of the tractor
hydraulic remote outlets.
INSTRUCTIONS FOR BOTH:
Connect the 1” I.D. x
216” long return line from the bottom of the
3
/
4
” pipe tee
on the ram control valve return directly to the filler open-
ing on the tractor’s hydraulic system. On many tractors,
the return line can be inserted directly into the filler
opening. The hose should be securely tied in place and
wrapped with a rag or duct tape to prevent contamina-
tion. Special care should be taken to remove the hose
when not in use, to prevent rainwater or dirt entering
the opening. Screw a
3
/
4
” pipe cap on the hose end to
keep it clean. Special filler opening adapter fittings are
available for most popular tractor models. Contact your
supplier for prices and availability.
NOTE:
Due to the necessary discharge rate of
hydraulic oil, this line
CANNOT
be connected to the
tractor remote outlets. To do so will restrict the drop
rate of the driving ram such that it will not properly
drive a post.
NOTE:
If the hydraulic oil return hose is too short for
your tractor application, you may increase the length
by ordering hose extension kit #2504141 (4’ ext.).
NOTE:
On both models, route the hoses to the tractor
hydraulic remotes so that they will not be pinched or
caught by the movement of the positioning mount or
loader.
Use nylon tie straps to retain the hoses in position.
Be sure to allow a loop of hose between the loader
and the main frame of the post driver mount to allow
for movement.
6. Stand clear of the driving ram assembly and raise the
completely assembled unit approximately 10 inches
with the 3-point of the tractor. Operate the hydraulic
valve on the tractor so that oil flows from the tractor to
the valve and returns by the tractor fill opening hose.
Tie the tractor hydraulic valve handle into operating
position with a tarp strap. The tractor should be
operated at an idle until the system is charged with oil.
Be sure to check the tractor hydraulic oil level after
charging the system.
Now operate the hydraulic levers on the multi-spool
valve. This should cause the driving ram assembly to
pivot, side to side and front to rear. The cylinders will
have to be cycled several times to remove all the air
from the cylinders and lines. Be sure to check the trac-
tor hydraulic oil level after charging the system.
Special orifice fittings have been installed at the
hydraulic cylinder ports to restrict the flow and cause
the cylinders to operate in a slow, smooth manner.
7. Attach the circular (bulls-eye) level as shown in the
parts illustration. Adjust the alignment of the level as
follows: using a 2’ or longer carpenter’s level, adjust
the driving ram with the alignment cranks until the ram
is plumb front to back and side to side. Tilt the top of
the driving ram slightly to the rear to allow for recoil
when the ram drops. Now adjust the valve mounting
bracket and the bubble level bracket so the level bub-
ble is centered in the level circle (see Figure G), then
tighten all bolts.
FRONT LOADER HYDRAULIC MOUNT ASSEMBLY:
Connect a
3
/
8
” I.D. x 36” long hose (see Figure F, ref. #22)
from the inlet side of the ram control valve to the 90°
street elbow in the 2 spool valve (see Figure F, ref. #33).
INSTRUCTIONS

LUBRICATION
The Post Driver is designed with “SPECIAL” polyethylene
slide blocks for long, trouble-free operation.
• Oil or grease applied to the slide channel will make
the operation smoother and if applied after use will
help keep rust from forming in the channel.
• There are grease fittings on the large side to side pivot
tube and on all the manual threaded tilt adjustment
nuts. A few shots of grease at the beginning of the
work day is recommended.
• It is recommended to apply grease or oil to the
threaded portion of the tilt adjustment cranks before
storage to help prevent rust from forming.
• Smear grease over the exposed portion of the plated
hydraulic cylinder rod after use to help prevent pitting
and rust from forming. If Post Driver is going to be
stored outside this is very important.
• The hydraulic control base has a grease fitting on the
large, side to side, pivot tube and one on the lower,
front to rear, pivot pin.
BEFORE YOU START
Review the assembly instructions to be sure the Driver
is properly assembled and plumbed correctly for your
tractor hydraulic system. The control valve return hose
must be connected directly to the tractor hydraulic oil fill
opening – NOT to the tractor remote outlets.
(See
Assembly Instruction, item #5.)
Refer to the Hydraulic
Valve Section (pages 15-17) for open-center and closed-
center tractor hydraulic system requirements. Be sure
the tractor hydraulic oil and filter have been serviced
according to the tractor manufacturer’s recommenda-
tions before using the Post Driver.

PRE-OPERATION CHECKLIST
(OWNER/OPERATOR RESPONSIBILITY)
____ Review and follow safety rules and safety signs on
pages 3 through 12.
____ Check that Post Driver is properly and securely
attached to tractor loader.
____ Lubricate all grease fitting locations.
____ Check that all hardware is properly installed.
____ Check that no one enters the area of machine
operation. Always keep bystanders at a safe dis-
tance from the post driver.
____ Know your controls and how to stop tractor, engine
and PTO quickly in an emergency. READ THIS
MANUAL AND THE ONE PROVIDED WITH YOUR
TRACTOR AND LOADER.
____ 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, implement and all controls.
DANGER!
Beware of low electrical wires when loader is
raised. Serious injury or death can result if contact is
made.

” I.D. x 24” long hose from the control
valve work port to the Post Driver hydraulic cylinder
port.
5. Install the hydraulic package. Refer to Figure E for cor-
rect location and orientation of components. Use a
good grade hydraulic thread sealant at all pipe thread
connections. (Do NOT use Teflon tape sealer.)
Do NOT use thread sealant on O-ring fittings.
NOTE:
Install the O-ring to pipe thread adapters in the
valve ports as shown in Figure E.
