But with so many options on the market, how do you choose a post rammer that won't let you down when you're in the back paddock and the weather's closing in?
Selecting the right post rammer isn't just about buying the biggest or most expensive model. It's about finding equipment that suits your specific farm conditions and workload.
Farm equipment takes a beating. Your post driver needs to handle constant use in harsh conditions, from the scorching summer sun to freezing southerlies. Here are some key points to look for:
Quality equipment might cost more upfront, but farms are harsh environments where inferior machinery quickly shows its limitations. When breakdowns occur in remote areas of your farm, the costs go beyond just repairs – there's also lost productivity and project delays to consider.

What works well behind a 120hp tractor might be completely incompatible with your 90hp tractor. Make sure you have a solid grasp of your current equipment before picking out a post rammer. Modern post rammers are designed to mount to a range of tractor sizes and other machinery types, including:
Before purchasing, carefully assess what size tractor you'll be using with your post rammer throughout its entire lifespan. Will you upgrade or change the size of your tractor in the next few years? Are you considering adding a digger to your equipment fleet?
New Zealand's diverse landscape throws up everything from rocky Canterbury plains to Taranaki papa. Your post driver needs sufficient hitting power and the correct accessories to handle the toughest conditions on your property. When tackling tough terrain, look for:
Time spent setting up equipment is time not spent fencing. A post rammer that is difficult to set up on your tractor, digger or skid steer will result in more downtime. Innovative hydraulic designs have addressed this with features that speed up the setup process and enable the same post driver to be used on multiple different machines.
Do you plan to transport the post driver around your farm, or between different farms? If so, you need to consider the different mast heights that are available. Even basic post drivers are available with a hydraulic hinged mast, meaning you can safely transport your post driver around your farm while maintaining a high level of hitting power thanks to the tall mast. This hydraulic hinge option also allows you to store your post driver in a shed, meaning it stays in better condition for longer.
Consider:
With machinery, it is inevitable that something will eventually go wrong. When breakdowns happen, having local support can be the difference between a minor inconvenience and a complete work stoppage. A good dealer network means:
Local dealers also provide valuable advice on maintenance schedules and can often identify potential issues before they cause field failures.
Kinghitter Series 1
With over 45 years of experience, Kinghitter's entry-level Series 1 offers remarkable quality for smaller operations. The 230kg hammer provides sufficient force for most soil types, while the simple hydraulic system is reliable and easy to maintain. A budget-friendly option suitable for lighter use. While not as robust as premium models, it handles standard fencing jobs on flat to rolling terrain, in easy soil types.
Kinghitter Series 2i
The Series 2i steps up with a 250-300kg hammer and "interchangeable" hydraulic system for faster operation without needing a high-flow dump line. The heavy-duty 350 Grade 150UC mast handles tough conditions and allows for the full range of accessories. Another solid New Zealand-made option with good hydraulic performance and compatibility with various tractor setups.
Kinghitter Expander 2i
With a telescopic mast extending from 3.2 to 5.0m, the Expander 2i allows precise control even in areas with limited headroom. The Kinghitter series 2i "interchangeable" hydraulic system does not require a high-flow hydraulic dump line. These high-flow dumps are fitted to every other hydraulic post driver manufactured globally, however, they can create issues with the oil overheating and aeration. The unique Kinghitter interchangeable hydraulics are an industry game-changer that ensures durability and consistent performance. A premium option popular with contractors, featuring sophisticated hydraulics and good ergonomics.
Before comparing models, ask yourself:
Tractor-mounted post drivers are the most common option and offer:
Digger-mounted options provide:
Many farmers find that tractor-mounted options with good side-shift capabilities offer the best balance for most fencing jobs.
The initial price difference between budget and premium post rammers can be significant, but this gap often narrows when considering the total cost of ownership. Budget options typically require more frequent repairs, have shorter lifespans, and can cause significant delays during critical fencing periods.
Quality post rammers usually cost more upfront but deliver savings through:
Reputable dealers will arrange demonstrations of their post rammers. These sessions provide invaluable hands-on experience with the equipment. You can see the machine in detail and test features like the valve bank control and ergonomics, which become significant factors during long fencing days.
Choosing a post rammer comes down to balancing initial cost against long-term performance. For most New Zealand farmers, investing in quality equipment that's built for local conditions and backed by local support proves the wisest decision.
A quality post rammer isn't just a purchase, it's a long-term investment in farm infrastructure and productivity. The right choice means fewer frustrations, more efficient fencing, and ultimately, better returns for your farming operation.
It is highly recommended that you speak to someone who understands your requirements and can equip you with a machine that will suit your ground conditions, price expectation, machine weight limitation, and provide ongoing support once you have made your decision.
