Powertech Honda GX50 Post Driver 120 – "The Hulk"
When only the biggest and toughest post driver will do, the Powertech Honda GX50 Post Driver 120, affectionately known as "The Hulk", stands in a class of its own. Purpose-built for professional fencing contractors, rural contractors, farmers, councils, and civil construction crews, the PPD-120 is the largest and most powerful single-person handheld post driver in the Powertech range.
Designed to drive everything from small planting stakes and star pickets through to 100NB steel strainer posts and large timber posts, the PPD-120 has earned its reputation through years of proven performance in Australia's toughest conditions. As a result, it has become the post driver of choice for contractors who demand maximum impact power, outstanding reliability, and uncompromising durability.
For more than six years, the PPD-120 has been field-tested by professional fencing contractors across Australia. Many operators have driven hundreds of 100NB steel strainer posts using a single machine, demonstrating the exceptional durability that earned this model its legendary nickname—"The Hulk."
Powered by the Genuine Honda GX50 4-Stroke engine, the PPD-120 delivers exceptional fuel efficiency, reliable starting, and industry-leading performance. Combined with larger hammer internals and a hydraulic oil and grease-lubricated gearbox and piston housing, the machine produces an impressive 25–60 joules of impact energy, providing the power needed for the most demanding fencing applications while requiring minimal maintenance.
Despite its incredible capability, the PPD-120 remains the largest single-person handheld post driver on the market. Weighing 24 kg, it offers an outstanding balance of portability and impact performance, allowing contractors to complete heavy-duty fencing projects without the need for larger machinery.
Designed with operator comfort in mind, the machine features internal spring-mounted handles that absorb vibration, reducing fatigue during extended use. Furthermore, Honda's 360-degree inclinable engine allows reliable operation at virtually any working angle, making the unit ideal for uneven terrain and difficult access areas.
The Powertech-designed fuel tank and engine protection guard provides additional durability during transport and operation, while the supplied carry case and tool kit keep the machine protected and ready for work.
Supplied complete with six interchangeable post sleeves (45 mm, 55 mm, 60 mm, 78 mm, 100 mm and 120 mm), the PPD-120 is ready to tackle an extensive range of fencing applications. In addition, Powertech offers a comprehensive range of specialised adaptors, including compatibility with the Rotech Drive-Tight Strainer Post System, providing even greater versatility for professional contractors.
Please Note: Driving 100NB steel strainer posts requires the optional 118 mm Steel Strainer Post Adaptor, available separately.

Ted Edwards –
I have been dealing with Jamie at Powertech Machinery now for 3 years.
My first purchase was a 120mm post driver.
I rang Jamie again about the standard / maxi picket post adapter which slides onto the post, again Jamie recommended it as it holds the post as you are driving it, money well spent.
I’ve also purchased the 118mm adapter that I haven’t used yet but I’m sure it will be useful.
I purchased the 2 metre wooden / star post puller for my excavator which lifts old wooden and star posts with ease.
My latest purchase on the 22nd July 2026 is a V3 post hole digger and 300mm extension.
All machines and accessories are quality and perform as advertised. I can’t fault Jamie’s friendly and professional service and prompt delivery from Western Australia to Tamworth area NSW.
With Jamie’s knowledge and quality products I highly recommend Powertech Machinery.
Many thanks.
Ted.

I’m very happy wth the post driver (PPD-120) with the Honda GX50 motor that I purchased last year. It’s very reliable and easy to use and maintain, I’ve knocked in about a hundred 100NB 8ft steel strainers , 4 foot in the ground in all sorts of different country and haven’t had any problems yet. Also The service at Powertech is second to none and their freight service that delivers within 1-2 days of purchase, when you’re on the other side of the country. I’d recommend them to anyone. Great , affordable product that’s compact.
Steve & Bec Hart –
Ripper little unit, we have the PPD-120 and it smashes everything in, no worries. Hasn’t missed a beat.
Sarah Moy –
Purchased a 120 Post Driver works great and very powerful for a hand held unit definitely recommend this product
Service from Jamie at Powertech was excellent
Scott Deacon –
Jamie on the other side of the country was able to very quickly connect me with a local Canberra dealer (Capital Tools) with a GX50 in stock.
A weekend on the property driving Gal 100NB Strainers with the GX50 has made such a difference. No more digging holes!!
The GX50 easily drove over 7 Strainers in a morning session, setting us up for weekend of fencing fun.
The GX50 didn’t miss a beat, if you’re second guessing the investment – then don’t, just buy the GX50 and never look back.
Jesse Touma –
The Powertech Honda GX50 Post Driver (PPD-120) is a great addition to my fencing gear. I haven’t had a strainer it can’t drive. It is very efficient, mobile, reliable and fast. Haven’t had any issues with it.
Dale Harrop –
Unbelievable machine loved it from the first time I used it. No trouble driving 100nb 1m in iron bark quartz country, close to 1.5m 50nb in same dirt. Would recommend this to anyone
Jeffrey Brown –
PurchasedI the Post driver PPD-120, what a machine never misses a beat. Powertech machinery is high quality the time the machine saves you per job is well worth the price, and you never have to worry about the motor starting it’s a Honda. Adaptors are top quality. I was so impressed i just purchased the PPD-80 as a second machine for the young boys to use a bit lighter for star pickets. Powertech’s products stand out for their quality, and Jamie is the reason I made the 2nd purchase great knowledge and customer focused, ask yourself a question when was the last time you made an online purchase and the business rang you to confirm the order and again when it was delivered can’t put a price on great customer service well done Jamie and Powertech.
Samuel Kapeen –
I had ordered the 120 post driver after doing months of research on the most efficient way that wouldn’t break the bank for my fencing project on my farm. I run 80 NB post 1000mm deep as my strainer posts on a star picket fence. This post driver would drive my strainer post with absolute ease. I was very surprised.
For the money and time saved using this product I couldn’t be happier. Neighbours are super impressed and it has been a game changer to the way I do my fencing.
I am a very happy customer and coming from a mechanical engineering backround I can vouch for the quality that has been put in to this unit.
100% recomened and you won’t be disappointed.
Thanks powertech machinery team for your service and your effective communication.

I recently purchased the PPD-120 post driver from Powertech Machinery and couldn’t be happier! It’s worked brilliantly—I’ve driven over 100 star pickets into the ground with ease. The machine is powerful, efficient, and a total game-changer for fencing work.
Big thanks to Jamie for the fantastic support—he helped me choose the right adapter for 100NB strainer posts, which my machine should handle with no issues at all.
Highly recommend Powertech Machinery to anyone doing large-scale fencing, especially for horse properties. Great gear and even better service!
Jason Bick –
Jamie’s Service is second to none.
My Powertech 120 is an absolute machine, and has done everything and more that I’ve asked of it. Highly recommend Powertech Machinery.
Terrie Hart –
I have found this driver easy to use and I’m extremely happy with the job it has done for me in the last 2 years I have been driving drill stem for a wild dog fence in about 1400 to 1500 Shawn
Jake Bulst –

Parrs Rural Fencing
This post driver is the only tool we use to drive all our 100nb strainers posts in with. we have easily driven over 1000 posts in with not a drama at all can handle and has handled all soil types around our region . we highly recommend to any other contractors or farmers doing there own fencing for the price point and what it is capable of is a no brainer will be adding another one to our trailer
Kitika Davies –
This postdriver is an absolute beast!
After been let down by an ebay special 2 stroke toy that could barely put a picket into sand, wasting my time and money I needed a driver that would work. And this big thumper just drives and drives pickets in where they are needed. Over a span of 1km of dry, hard almost concrete like clay/gravel/rock it just kept thumping star pickets and maxys in that I couldn’t even get started by hand. I wouldn’t even think about fencing without having this in the toolbox now.
This unit has an extremely quiet engine, barely audible with earplugs in and just keeps purring along and beating posts in like nothing else.
If you are in the market for a postdriver, this is the one. After sales support and knowledge from Jaime is also fantastic answering any of my questions I’ve had about usage and maintenance.
Country Wise Rural Contracting –
We’ve been using this post driver for years as part of our fencing business, and it has proven to be a reliable and essential tool.
The power and efficiency it offers make driving posts into the ground a lot easier, even in tough soil conditions. Its ergonomic design allows for comfortable handling, which is crucial during long workdays.
Over the years, it has consistently delivered excellent performance, requiring minimal maintenance. If you’re looking for a durable, high-performance post driver, we highly recommend this one for any fencing job.
If the machine’s exceptional performance wasn’t enough, the customer service provided by Jamie is top-notch. Jamie goes above and beyond to ensure you get the right accessories and adaptors for your specific needs, answering all questions promptly and with genuine care. He truly knows his product inside and out and ensures every customer leaves satisfied. It’s rare to find such a combination of excellent equipment and service, making this purchase a great experience from start to finish.
This post driver is a serious investment in efficiency and durability for fencing professionals or anyone with large-scale fencing projects. Highly recommend both the product and Jamie’s outstanding support!

Great driver and just as quick as using an air driver without having to cart the large air compressor.
Benjmcinnes –
I’ve been using the PPD 120 for over a year now reliably driving hundreds of 100nb strainer posts through decomposed granite to a depth of 1800mm and thousands of 75x75x3 tube to 600mm without any failures.
The team at Powertech were very professional and I highly recommend this product.

With the ground like concrete here I had some doubts about whether or not this unit would cope with driving in Waratah Ezy-Slot Strainer posts. Gal. Angle: 75mm x 75mm x 6mm https://www.waratahfencing.com.au/products/posts/strainer-assemblies/ezyslot-strainer-post/
With no pilot holes, just hope and persistence this driver has eaten the job, with relevant ease. Amazed me.
I’ve had discussions with Jamie about an adaptor to make it easier to drive the right angled profile, so I will have this manufactured for myself future use.
Brilliant service and great product, which I would thoroughly recommend to anyone in the market for some great gear. The service and follow up by Jamie is incredible. Such a pleasant change.
Guy Curtis (verified owner) –
This driver has been fantastic for all of our property fencing, and has really saved our backs getting strainer posts in. We’ve saved so much time too.
The customer service has been incredible – Jamie was so quick to respond to a query and was professional and a great source of knowledge. Would highly recommend!
Phillip McCormack –
This driver is the best. As a fencing contractor it has saved me a lot of time. It is everything i hoped for when I brought it and more. Service and advice from Jamie is second to none. I highly recommend this driver
Chase Whittle (verified owner) –
Got this driver to install fencing on my property, i am extremely happy with the quality and the performance. I have soft top soil then into some coffee rock/clay type soil, i put a pilot hole in to 500mm and this driver has no issues putting a 100mm pine post down to 1.2mtr. It is balanced well easy to use and maintain.
Jamie’s service is second to none he was very helpful and easy to communicate with any calls that he missed were always returned.
i Would definitely recommend Power tech.
Nigel –
As a contractor who’s been using this model post rammer for some years now, I highly recommend it for its durability & ease of use.
This is one piece of equipment any fencer should have
Nelson mcfee –
This driver is one of the best machines I have used, it is a lot quicker than an air driver and also drives just as quick as the 100cc petrol ones, the bonus with this one is that you can operate it on your own and you don’t need any machinery to lift it onto posts and cart it around.The customer service from power tech was very professional and helpful, I would highly recommend power tech and there team for good quality gear and helpful/ polite customer service.
