SKID STEER REQUIREMENTS AND PREPARATION
Both the manual and hydraulic positioning skid steer post driver mounts are designed to fit skid steer units with the “Universal” (Bobcat) style quick-attach loaders.
The model 16, 22Q, and 26Q post drivers vary as to the size post they can drive and the amount of impact force they can strike a post with. (Refer to Specifications.)
A larger size skid steer unit is required in relation to the size of driver used. A general rule is that the skid steer specified operation lift capacity should be at least 1.25 times the weight of the post driver attachment.
A post driver is equipped with adjustable legs which should be adjusted to the proper height and have the weight of the driver on them while driving the post. This makes the driver a more stable unit and eliminates shock loads on the skid steer loader.
Be sure that the skid steer unit is in good working order, particularly the hydraulic system, prior to using the post driver. Be sure the skid steer hydraulic oil and filter have been serviced according to the skid steer manufacturer’s recommendations.
Be sure your skid steer and loader is in good condition. Read all the safety precautions and make sure all operators are familiar with the safety rules of operation.
Post drivers are tall and visibility of the top of the post driver may be obstructed by the top of the skid steer unit operators cab. Always be aware of low doorways, low limbs, and especially low hang­ing wires.
A heavy load can cause instability in driving a skid steer unit. Always drive slowly – especially around turns. An unstable skid steer unit could steer badly and possibly tip over, causing damage, injury or even death.
INSTRUCTIONS
These instructions are for the models HPD-16 HSS/P, HPD-22Q HSS/P, and HPD-26Q HSS/P skid steer mounted hydraulic post drivers.
The model 16, 22Q, and 26Q HSS/P post drivers have a hydraulic motor with a self-contained hydraulic system. The hydraulic system of the skid steer unit powers the motor only.
The Models HPD-16 HSS/P has the Quick Change
Cylinder Cap.
The models HPD-16 MSS and HPD-22Q MSS are manually adjusted post drivers. The manual adjusting base have two threaded cranks to set the side to side and front to back positioning of the driving ram.
Models HPD-22Q and HPD-26Q have both the Quick Change Cap and the new longer lasting Quick Change spring assemblies.
The models HPD-16 HSS/P, HPD-22Q HSS/P, and HPD-26Q HSS/P have the driving ram positioning con­trolled hydraulically. A two spool hydraulic valve controls the front to back and side to side movement for aligning to a vertical ram position. A separate single spool valve controls the raising and lowering of the driving ram.
The hydraulic valve that operates the driving ram is a convertible valve and is shipped ready for OPEN center hydraulic systems. Do not change this valve to a closed­center valve. This convertible feature is only required for some farm tractor applications.
Post drivers are a tall attachment to your skid steer unit. Always watch for low clearance problems such as low tree limbs, doorways, or low hanging wires.
WARNING
CAUTION
PACKAGING
The Post Driver is shipped as bundles.
1. The hydraulic base mount unit, partially pre-plumbed.
2. The driving ram assembly, on a pallet.
3. A hydraulic package for the ram, in a carton.
4. A package for the hydraulic base, in a carton.
5. Post Holder, in a carton.
Please inspect these bundles for any obvious signs of damage before attempting to assemble the Post Driver. Unpack all the bundles and lay out the various parts.

INSTRUCTIONS (continued)
ASSEMBLY & MOUNTING
The following procedure is recommended for assem-
bling the Skid Steer Mounted Post Driver.
Carefully follow instructions for final assembly.
Before attempting assembly check the following items. Having all the needed parts and equipment readily at hand will speed up your assembly task and will make the job as safe as possible.
• Check for fasteners and pins that were shipped with
the post driver. Some hardware coming from the fac­tory has been installed in the location where it will be used. If a part or fastener is temporarily removed for assembly reasons, remember where it goes. Keep the parts separated.
• Have a fork lift or loader along with chains and safety
stands that are sized for the job ready for the assembly task.
• Have a minimum of 2 people at hand during assembly.
• Check to see that all nuts are properly tightened.
Refer to the “exploded view” of the skid steer mounted post driver on pages 25 thru 35 of this manual. Become familiar with the relationship of the various components and parts shown.
1. Connect the post driver base mount (manual or
hydraulic) to the “universal” quick-attach plate on your skid steer loader. Flip the spring loaded latch pins to the “latch lock” position and check to see they are properly latched.
Raise the unit about 21/2ft. from the ground and lower the adjustable stabilizer legs on each side of the mounting frame. Pin each leg into position.
Operate the bucket tilt cylinders until the mounting frame is vertical and then lower until the legs are supporting the unit.
2.
The hydraulic base mount is shipped with the hydraulic system partially plumbed and ready to accept the driving ram assembly. The multi-spool valve and mounting plate may be detached and shrink wrapped in place. Simply remove the shrink wrapping, swing the mounting plate into position and install the mounting bolts.
3. Prepare the driving ram for attaching to the hydraulic base mount. To do this, first lower the driving ram to its lowest transport position. The driving ram is shipped in the upper transport position for compact­ness. To lower the ram, pull the transport lock pin,
allow the ram to lower (approximately 10 inches) and replace the transport lock pin. This should be done with the Driver laying on the shipping pallet. The ram is spring loaded downward. Stand clear of the ram when the pin is removed (see Figure A).
NOTE: This step of repositioning the driving ram is necessary in order to make the mounting bolts at the correct height when the unit is stood upright for the next step.
FIG. A
4. Attach the driving ram assembly to the hydraulic base mount. A chain hoist or forklift can be used to stand the driving ram assembly to its normal (vertical) working position. Take care not to damage the hydraulic cylinder or carriage when lifting the unit. Once the ram assembly is upright, remove the six (6) nuts and lock washers from the mounting bolts.
Align the mounting bolts with the six (6) holes in the mounting channel and secure with the nuts and lock washers.The mounting channel on the hydraulic base mount will probably have to be positioned by hand to get the mounting channel and carriage lined up.
NOTE: The mount is shipped with straps that lock the hydraulic cylinders. To assemble the unit, it may be necessary to remove the straps. It is important to re­install the straps once the unit is assembled.
NOTE: The driving ram assembly will be unstable until the hydraulic cylinders are filled with oil once all plumbing is completed.
NOTE: One mounting bolt goes into a blind hole and does not get a nut and lock washer. Due to trapped air, it may be necessary to operate the control levers on the multi-spool valve to position the mounting channel on the hydraulic base unit. Plastic hose end caps may have to be removed to allow trapped air in the hydraulic cylinders to escape. DO NOT
ATTEMPT TO CONNECT THE VALVE TO THE SKID STEER AND OPERATE IT AT THIS TIME. When
properly mounted, the bottom of the driving ram should be resting on the same level surface as the mounting base.

Connect the 3/4” I.D. x 24” long hose from the control valve work port to the Post Driver hydraulic cylinder port.
NOTE: The port and end of the 24” hose has a NPT (pipe thread) type connection. Use a good grade of thread sealant at this connection. (Do NOT use Teflon tape.)
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.
WARNING
HYDRAULIC CONNECTIONS
Check all hose and fitting connections. Make sure the hoses are not twisted or kinked and that they will not be pinched during operation of the post driver or the skid steer unit.
MOUNT ASSEMBLY: Connect a 3/8” I.D. x 36” long hose from the inlet side of the ram control valve to the 90° elbow (#27) in the 2 spool valve.
Refer to Figure C and assemble the swivel tee (#31) and the 3/4” to 1/2” reducer bushing (#30) to the 90° outlet port fitting in the single spool ram control valve. Then connect a 3/8” I.D. x 36” long hose (#32) from the reducer bushing to the 90° elbow (#33) that is connected to the two spool valve.
Connect the 3/4” I.D. x 48” long return line from the bot­tom of the 3/4” tee (Ref. #31) on the ram control valve to the hydraulic tank.
Pour 5 gallons of good quality hydraulic oil in the reser­voir (this will temporarily fill tank above sight glass). Operate unit and cycle each hydraulic cylinder to fill with oil. Then check sight glass and add oil if necessary.

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. A few shots of grease at the beginning of the work day is recommended.
• 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.

ASSEMBLY (continued)
NOTE: Route the hoses to the skid steer so that they will not be pinched or caught by the movement of the positioning mount
6. Stand clear of the driving ram assembly and raise the completely assembled unit approximately 6 inches with the skid steer loader. The driving ram assembly will probably lean out of its normal position. Operate the hydraulic valve so that oil flows from the skid steer to the multi-spool valve and ram control valve and returns to the hydraulic reservoir. The skid steer engine should be operated at an idle until the system is charged with oil. Remove the two cylinder locking straps from the positioning cylinders. 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 skid steer 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 bub­ble is centered in the level circle (see Figure D), then tighten all bolts.

BEFORE YOU START
Review the assembly instructions to be sure the Driver is properly assembled and plumbed correctly for your skid steer hydraulic system. Be sure the skid steer unit’s hydraulic oil and filter have been serviced according to the skid steer units manufacturer’s recommendations before using the Post Driver.
OPERATING INSTRUCTIONS
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 skid steer 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 dis­tance from the post driver.
____ Know your controls and how to stop skid steer,
engine and PTO quickly in an emergency. READ THIS MANUAL AND THE ONE PROVIDED WITH YOUR SKID STEER.
____ 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 skid steer, post driver and all controls.
Beware of low electrical wires when loader is raised. Serious injury or death can result if contact is made.
OPERATION
Observe all operating and safety instructions in this manual and those on the Post Driver before using this machine.
1. Position the skid steer for driving a post.
2. On the skid steer mount with adjustable legs, adjust
the legs so that when the driver is at the desired height, the legs will be on the ground supporting the weight of the driver. Always lower loader so weight of loader and driver is on the legs.
3. Set the skid steer brakes. Raise the ram slightly and
remove the transport pin.
4. Align the driving ram vertically by use of the “bulls-eye”
bubble level and the multi-spool hydraulic valve handles.
5. Raise the driving ram by lifting up on the control valve
handle. NOTE: Do not allow the ram to continually
hit the urethane bumpers at the top of the car­riage. Tractors with high volume hydraulic pumps will cause the ram to raise very fast. If the ram
raises too fast, turn the up stroke limit screw into the valve body to limit the amount of handle movement (see Figure E). Tighten the lock nut to keep the limit screw in position. Raise the ram so that it is 18” to 24” above the top of the post. The tractor hydraulic control valve should be tied in the “ON” position so the Driver is controlled solely by the Post Driver control valve.
6. Place the post within the driving ram. The back of the
post should be against the web of the I-Beam and centered between the flanges. Stabilize the post using the special “Post Holder Tool” provided.
FIG. E
DANGER
20
NEVER hold the post with your hand. Always use the post holder or the special STEEL T-POST Holder when driving steel T-posts. Order part #814490.
OPERATING INSTRUCTIONS (continued)
Improper use of loaders can result in serious injury or
death to the skid steer operator.
For optimum stability, visibility and safety:
• Carry the post driver slowly and low to the ground.
• Operate the loader controls smoothly, avoiding jerky operation.
• When driving posts on a slope, always have the post driver facing uphill.
• Only use a skid steer equipped with a ROPS cab or roll-over protective structure.
• Use particular care when working on inclines and hill­sides.
• Avoid holes, ditches, and obstructions which may cause skid steer loader to tip.
• Never allow anyone to walk or work under a raised loader.
• Be sure that people, livestock, or pets are not stand­ing near the machine while operating.
• Make sure there are no buried utilities in work area (call 811).
DRIVE POSTS SAFELY
7. Stand at a 45° angle to the post – not directly in front of the post. Be sure all bystanders are at a safe dis­tance from the Post Driver.
8. Drop the driving ram by pushing “Full Down” on the control valve handle.
9. Repeat raising and dropping the driving ram until the post is to the desired depth. Be sure the ram slide blocks are not “BOTTOMING OUT” on the urethane bumpers. Likewise, do not raise the ram to its extreme up position with each stroke.The ram should normally be raised 18” to 24” above the top of the post. Once the post is deep enough to be stable, it is no longer necessary to hold the post with the “POST HOLDER TOOL.” Stand back and “DRIVE” the post.
10. In dry or light rocky conditions, cutting a point on the post may be beneficial. The point should be centered on the post to prevent the post veering to one side.
11. When driving steel “T” posts do not raise the ram as you would for wood posts. Usually, raising the ram 4” to 6” is enough for steel “T” post. Too much impact on steel “T” post can cause the post to buckle or bend.
12. Re-engage the transport lock pin when finished with the job.
When traveling on public roads, whether at night or during the day, use accessory light and devices for adequate warnings to operators of other vehicles. Comply with all federal, state and local laws.
Install the two cylinder locking straps on the hydraulic
positioning cylinders before transporting long distances.
Carry load low.
Check visibility. If visibility is impaired, reduce speed or
consider other means of transport.
Allow for additional length of loader on tractor while
turning.
Select a safe ground travel speed when transporting from one area to another. When traveling on roadways, transport in such a way that faster moving vehicles may pass you safely.
When traveling over rough or hilly terrain or when mak-
ing turns, slow down and use extra care.
Read all the safety warnings in the front of the manual.

STORING THE POST DRIVER
Following operation, or when disconnecting the post driver, stop the skid steer unit, set the brakes, lower the loader, lower the driver ram to it’s lowest position and engage the transport lock pin. Install the two locking straps on the angle cylinders and make sure the adjustable legs are positioned correctly.
Shut off the engine and remove the ignition key.
Lower the ram to the lowest position and engage the transport lock pin. This position will have the hydraulic cylinder rod fully retracted into the cylinder and will be self-protecting.
Make sure driver will be located on a solid surface and
in a location away from children, animals, or traffic area.
Inside storage is preferred to prevent deterioration of the springs, hoses, etc. For safety, the Driver should be securely blocked for stability.
To store the skid steer mount with adjustable legs, locate the transport locking pin into the higher hole location in the ram and then adjust legs to same height.
Smear grease over the exposed portion of the plated hydraulic cylinder rod to prevent pitting and rust from forming.
It is recommended to apply grease or oil to any exposed portion of the tilt cylinders or threaded cranks to help prevent rust from forming.
Thoroughly clean the grease zerks before servicing. Dirt mixed with lubricant will rapidly wear parts and destroy bearings. Keep it clean. Lubricate all grease fittings prior to storage.
MAINTENANCE AND ADJUSTMENTS
Before servicing the machine, engage the parking brake or place the transmission in “Park,” shut off the skid steer and remove the key. Relieve all hydraulic pressure in lines.
Do not get under machine to make measurements or adjustments without securely blocking implement first.
• Serious injury or death may result from disengag­ing the attachment when the attachment is in an unstable position. Place the attachment in a stable position before disengaging.
• Hoses for the attachment must be disconnected before the quick attach is disengaged. Pulling the attachment with the hoses could result in damage to the prime mover or the attachment.
If the machine is used in heavy duty conditions, the maintenance operations must be carried out more frequently.
Thoroughly clean the grease zerks before servicing. Dirt mixed with lubricant will rapidly wear parts and destroy bearings. Keep it clean.
Check the pins at the ends of the loader arms. Make
sure they are locked in place with the linchpins.
Periodically check all bolts to make sure they are tight
(except those that are supposed to be loose).
Check hydraulic hoses. Make sure they are not chafed
or pinched. Replace any damaged hose.
Check hydraulic hoses and fittings for leaks. Repair any leaks immediately. Never use your hand to check for a hydraulic leak when system is under pressure.
Replace any worn or damaged parts immediately. Do
not use post driver attachment with any damaged parts.
Make certain the safety and instruction decals are attached to the Post Driver. If they are lost, damaged, or painted over, order replacements.
Do not work under a raised loader unless it is securely blocked or held in position. Do not depend on the hydraulic system to hold loader and attach­ment in place.

NOTE: HSS/P Models require the valve to have the open center plug.
HYDRAULIC CYLINDER BASE ADJUSTMENT – HPD-16
Due to the design of the Driver carriage, it is necessary for both the base and rod end of the hydraulic cylinder to have a slight amount of freedom. This adjustment should only be necessary if the hydraulic cylinder is removed for servicing (see Figure G).
The “Special 7/8” Nut” (Part #815205) has the correct amount of freedom designed in. No adjustment is required at the rod end of the cylinder rod.
NOTE: These instructions are for the HPD-16 Models only.
DISASSEMBLY – CARRIAGE AND RAM ASSEMBLY
1. Lay the driving ram assembly face down on the floor or on a solid workbench.
2. Remove the transport lock pin. This will allow the ram carriage to move up, thereby relieving the spring ten­sion. Disconnect the upper spring bracket.
3. Remove the lock nut from the top of the cylinder rod using a 115/16” wrench and a 11/2” wrench on the step nut and push the rod back into the cylinder.
4. Now remove the hex nuts (or bolts for Models HPD­22Q and HPD-26Q) holding the transport lock pin bracket in place. Slide the carriage down and remove the hydraulic cylinder and springs as a unit from the lower end.
5. The carriage can now be removed from the upper end of the ram assembly.
HYDRAULIC CYLINDER DISASSEMBLY
1. Refer to the exploded view of your model post hole driver and become familiar with the parts and how they are assembled.
2. It is NOT necessary to remove the complete hydraulic cylinder to change any of the internal cylinder parts. These parts can be changed from the top of the cylin­der. (See following section on replacing the seal).
NOTE: If you need to replace the rod or rod guide, it may be easier to remove the complete cylinder. This will allow you to place the cylinder in a vise to remove the lower part of the cap (gland) from the cylinder tube.
NOTE: The lower hydraulic cylinder mounting bolts have stamploc hex nuts (

TROUBLE-SHOOTING GUIDE (continued)
PROBLEM POSSIBLE CAUSE POSSIBLE REMEDY
DRIVER RAM RAISES VERY FAST AND HITS TOP URETHANE BUMPERS
1. Post driver control valve “UP” limit screw needs adjusting.
2. Skid steer model has high volume hydraulic oil pump.
3. Operator continuously raising ram to the full height.
Adjust limit screw (see page 19).
Set throttle at lower speed to reduce volume of oil or if necessary, install an orifice in line to reduce volume of oil.
Only raise ram 18-20 inches to achieve full hit­ting force. Retrain operator.
SPRING AND/OR SPRING CLIP BREAK­AGE
1. Operator is continuously raising the ram to the full height.
2. Springs are cold.
3. Springs and clips are a wear item on post drivers. It is expected that these parts will have to be replaced depending on length of use and when being subjected to “hard driving” conditions.
It is only necessary to raise the ram 18-20 inch­es to achieve full hitting force. Retrain operator.
In colder temperatures, it will help to “warm-up” or “season” the springs by first only raising the ram 6-8 inches, then 12-16 inches, then normal hitting height. This allows the spring steel to warm-up and not be subjected to full stretch when cold.
DRIVER HAS EXCES­SIVE MOVEMENT OR BOUNCE
1. Top of post is not cut “square,” causing the driver to veer off at an angle.
2. Post driver mount may not be properly latched on skid steer loader.
3. Skid steer loader is not all the way down.
4. Adjustable legs on mount are not setting firmly on the ground.
5. Springs may be disconnected or broken.
6. Ground may be too dry or hard.
7. Post may be encountering a rock.
8. Driver ram may be improperly angled.
9. Skid steer may not be large enough to handle driver.
Re-cut top of post “square.”
Check lock pins.
Lower loader.
Lower loader or adjust legs.
Check and repair or replace.
Pointing the post may help. You may have to wait until it rains if ground is extremely hard and dry.
Relocate post 6-8 inches and try again. Pointing post may help in light, rocky soil.
If top of ram is angled away from post, ram will veer off post. Re-adjust ram angle.
Use larger, heavier skid steer.

MAKE EVERY DAY
A HOLIDAY FROM ACCIDENTS
Machinery should be operated only by those who are
responsible and are authorized to do so.
Stop the engine, lower all equipment, lock the brakes,
and remove the ignition key before dismounting from the tractor.
Never stand between tractor and implement while tractor
is being backed to hitch.
Loose fitting clothing should not be worn, to avoid catch-
ing on various parts.
Detach implement in area where children normally do not
play.
When performing adjustments or maintenance on an
implement, first lower it to the ground or block it securely at a workable height.
Only a qualified operator should be permitted on tractor
when in operation; no riders allowed.
Make certain everyone is in the clear before starting
tractor or raising or lowering equipment.
Operate the tractor and implement only while seated in the driver’s seat.
Reduce speed when transporting mounted implements to avoid bouncing and momentary loss of steering control.
A heavy load can cause instability of the tractor. Use
extreme care during road travel. Slow down on turns and watch out for bumps. Tractor may need front counter­weights to counter-balance the weight of the implement.
Reduce speed on hillsides or curves so there is no
danger of tipping.
Avoid driving too close to the edge of ditches or creeks.
Do not transport implement on public roads without
reflectors and slow moving vehicle emblem in daylight and with approved warning lights at night and other periods of poor visibility.
Due to the width of some implements, use extra caution
on highways, farm roads, and when approaching gates.
Always be sure the implement is in the proper position for
transport.
Keep alert and watch the front as well as the rear when
working with the implement.
