Rhino Pneumatic Post Drivers
Air powered post drivers — pneumatic post pounders, if that is what your crew calls them — hitting 1,700 blows per minute at a fraction of the weight of what they drive. Portable enough for one operator and one air line: T-post and ground rod through guardrail, dock pile and 12 in. sheet piling.
The short version
Pick by the post, then check the air. Every one of these is a portable, hand-held air operated post driver — the compressor is the only thing tying you down. PD-55 for T-post, ground rod and pipe to 3 in. PD-110 for 2–4 in. pipe, 4×4 wood and dock pile. PD-140 for guardrail and sheet pile. PD-200 when it is 6 in. pipe, 6×6 wood or 12 in. piling. Every one of them needs a compressor sized above the tool draw.
The Rhino PD Line: Air Powered Post Drivers for T-Post to Sheet Pile
Four air post drivers, separated by weight, air draw and the master chuck that grips your post. Pick the chuck below and the price updates.
Rhino PD-55
The installer’s default for twenty years. Drives T-post, ground rod, tent stake, grape stake, delineator post, form pin and fence post up to 3-5/8 in. One moving part – a double-valve reciprocating piston – so there is very little to go wrong.
Rhino PD-110
Steps up from the PD-55 in speed and heavy-soil tolerance, and drives a 2 in. post ten to fifteen feet deep for soil stabilization. Suited to 2 in. through 4 in. pipe and tube, structural forms, pin piles, dock piles and 4×4 wood.
Rhino PD-140
The guardrail and sheet pile machine, with a weight-to-performance ratio nothing else in the line matches. Low air consumption for its output, and available with a slotted chuck for sheet pile or a 4 x 6 chuck for guardrail.
Rhino PD-200
Outperforms a 90 lb jackhammer. Beams, round, square and rectangular tube, wood posts and stakes of any shape – up to 6 in. pipe, 6×6 wood, H-column guardrail and 12 in. sheet piling. Fewer, harder blows at 930 BPM.
PD Kits: The Driver Plus Everything It Needs
A bare post driver will not drive anything. It needs a throttle valve to fire, an FRL to stay alive, hose to reach the post and oil to run on. Every kit below already has all four.
What is in every PD kit
Every kit on this page ships with the same air train — the four things a pneumatic post driver needs before it will do any work at all.
Sized to the model you pick. Chuck adapters for other post profiles are sold separately.
Required — nothing runs without it. The 5 ft whip suits a 7 ft post; add a foot per foot above that.
Clean, regulated, oiled air. The FRL is what keeps the piston alive.
The run from the FRL to the tool, and a gallon of oil to start on.
Buy the four separately and you will spend more than the kit discount — which is the whole reason these packages exist.
Start With a Kit, Not a Bare Tool
Four packages across four models. Each one is the driver plus the full air train above, at a kit price that beats buying the pieces separately — and it means the crew is driving posts the day it lands instead of waiting on a second order.

Job-specific kits
Configured around one kind of post, with the chuck already fitted.
Each kit page lists the full pack contents. Not sure which covers what you do? Call the number at the top — we will build the list against your post and your compressor.
Hand-held, or carrier-mounted
Any Rhino pneumatic post driver can be hung with a chain or a strap from a mini excavator, skid steer, tractor, telehandler, forklift — anything on site strong enough to lift it. Nothing special is required to do it.
With the remote throttle valve, that is often the easier way to work: the machine carries the weight and holds the driver square while the operator steadies the post and runs the throttle from the ground. On long runs of sheet pile, guardrail or heavy pipe it takes the fatigue out of the job and keeps the post plumb.
Tell us how you plan to run it and we will spec the mount and the hose.
What Air Compressor Does a Pneumatic Post Driver Need?
This is the question that decides whether the tool works. Take the tool draw and add roughly half again for hose loss and duty cycle — starve the air and the driver slows down long before it quits.
| Model | Tool draw | Size compressor to | Typical unit |
|---|---|---|---|
| Rhino PD-55 | 42 CFM @ 90 psi | 85 CFM | Tow-behind 90 CFM, or a large shop compressor |
| Rhino PD-110 | 64 CFM @ 100 psi | 130 CFM | Tow-behind 130-185 CFM |
| Rhino PD-140 | 64 CFM @ 100 psi | 130 CFM | Tow-behind 130-185 CFM |
| Rhino PD-200 | 72 CFM @ 100 psi | 145 CFM | Tow-behind 185 CFM |

Already tow a compressor for breakers or drills? You very likely have enough air for a PD-55. See diesel tow-behind compressors and our air compressor buyer’s guide. Every driver also needs a throttle valve kit and a filter-regulator-lubricator — see PD series accessories.

How much faster is the next size up?
Rhino’s own rule of thumb: if a PD-45 drives a post in two minutes, the PD-55 does it in one minute, the PD-110 in thirty seconds, and the PD-140 in fifteen. Estimates in moist, light to medium soil — but the ratio holds. Stepping up a model roughly halves the driving time, which is why high-volume fence and guardrail crews buy heavier than they think they need.
Where Air Post Drivers Earn Their Keep
Fence and T-post
The pneumatic t post driver crews reach for on chain link, field fence and temporary fence — ground rod, delineator and form pin on the same chuck.
PD-55 →Guardrail
4 in. x 6 in. guardrail post and H-column, driven to depth without a truck-mounted rig. The PD-140G ships configured for it.
PD-140G kit →Dock and marine
Dock pile, pin pile and slotted sheet pile for seawall and dock building — hand-held or hung off a mini excavator.
PD-140S kit →Sign and channel post
Channel post, PostMaster, Telespar and square tube sign post, with the slotted or PostMaster chuck.
PD-140 →4×4 and wood post
4×4 through 6×6 wood post for pergola, dock frame and heavy fence — the 4 inch and larger post driver work the PD-110 and PD-200 were built for.
PD-110 →Pipe, pole and structural
2 in. through 6 in. pipe and pole, well points and structural concrete forms, including pipe driven ten to fifteen feet for soil stabilization. The pneumatic pole driver crews use for dock and sign standards.
PD-200 →Need self-contained instead? See Rhino gas post drivers and hydraulic post drivers, the full post driver category, or post pullers for taking them back out.

What two and a half minutes will tell you
Watch how little setup a pneumatic driver actually needs: connect the air, set the chuck on the post, and go. The clip runs the line from the PD-55 on fence work through the heavier machines on pipe and sheet pile.
Pay attention to two things — how fast the post goes down once the hammer is cycling, and how little the operator fights the tool. That is the 1,700 blows per minute doing the work instead of the person.
Pneumatic Post Driver Questions
What is a pneumatic post driver?
A pneumatic post driver is a hand-held air hammer built to drive posts. Compressed air cycles a reciprocating piston that strikes the post through a master chuck, so one operator sets T-post, pipe, guardrail or sheet pile without an auger, a tractor, or a hydraulic power pack. Rhino’s PD line runs at 1,700 blows per minute on the PD-55 through PD-140, and 930 heavier blows on the PD-200. Crews call them air post drivers, air operated post drivers, pneumatic post pounders, fence post pounders and t post pounders — all the same tool.
What size air compressor do I need for a pneumatic post driver?
Take the tool draw and add roughly half again for hose loss and duty cycle. The PD-55 draws 42 CFM at 90 psi, so size to about 85 CFM. The PD-110 and PD-140 draw 64 CFM at 100 psi – size to about 130 CFM. The PD-200 draws 72 CFM, so plan on a 185 CFM tow-behind compressor. Undersize the air and the driver slows down long before it stops.
Which pneumatic post driver do I need?
Match it to the post. The PD-55 covers T-post, ground rod, delineator and pipe up to about 3 in. The PD-110 handles 2 in. to 4 in. pipe, 4×4 wood, dock and pin piles. The PD-140 is the guardrail and sheet pile tool. The PD-200 takes 6 in. pipe, 6×6 wood, H-column guardrail and 12 in. sheet piling.
How much faster is a bigger driver?
Rhino’s own rule of thumb: if a PD-45 drives a post in two minutes, the PD-55 does it in one minute, the PD-110 in thirty seconds, and the PD-140 in fifteen. These are estimates in moist, light to medium soil, but the ratio holds – stepping up a model size roughly halves the driving time.
Can a pneumatic post driver drive dock piles and sheet pile?
Yes. The PD-110 drives dock piles and pin piles, the PD-140S with a slotted chuck drives sheet pile, and the PD-200S handles 12 in. sheet piling and heavy marine work. The PD-200 pile driving kit comes configured with the 7 in. chuck.
What accessories are required?
Every pneumatic post driver needs a throttle valve kit and a filter-regulator-lubricator. The throttle valve kit ships with a 5 ft hose whip that suits a 7 ft post – add a foot of hose for every foot of post above that. Air tool oil is not optional on these; the FRL is what keeps the piston alive. All of it is in every PD kit, or shop the pieces under PD series accessories.
Do you rent pneumatic post drivers?
We sell rather than rent, and we supply rental fleets, fence contractors and DOT crews directly. If you are weighing a pneumatic post driver rental against owning one, call us with your post count and we will run the comparison — start from an Economy kit and work up.
Air, gas or hydraulic – which should I choose?
Air gives you the highest blow rate and the lowest tool weight for the power, but you have to bring a compressor. Gas is self-contained and goes anywhere. Hydraulic runs off a power pack or a carrier. If you already tow a compressor for other tools, pneumatic is usually the cheapest way to add serious driving power.
Tell us the post, we will spec the driver and the chuck
Post profile, depth, how many a day, and what air you already have on the truck. We will match the model, the master chuck and the hose before anything ships.
