The Kinghitter Series 2i Post Driver is an extremely capable machine, designed and engineered in New Zealand for farmers and fencing contractors who demand strength, speed, and reliability. Built on over 45 years of industry experience while incorporating the latest innovations in post rammer design, the Series 2i sets the benchmark for durability and performance in all ground conditions.
Available with 4.0m, 4.3m, 4.5m, or 4.9m masts, the Series 2i post rammer delivers flexibility for different fencing requirements. Its heavy-duty 350 Grade 150UC mast withstands extreme post-driving conditions, while the hydraulic hinge (on 4.5m & 4.9m models) makes transport simple and lets you store the machine in standard sheds. The 25° angle tilts in all directions, provides greater accuracy and efficiency on steeper terrain, and gives you better post steering ability.
You can choose from hammer weights between 250–340kg, ensuring you get the right balance of machine weight and hitting power. The custom-built Italian valve bank offers smooth fingertip control, while Kinghitter’s interchangeable hydraulics system ensures fast hammer speeds and compatibility with tractors, skid steers, and excavators. Adjustable legs further improve stability and usability.
Fully compatible with the complete range of Kinghitter base combinations and accessories, the Series 2i can be configured to suit any fencing application. Beyond its unique product features, it’s the after-sales team and nationwide dealer network that truly set Kinghitter apart — ensuring your machine is set up correctly, supported with parts, and backed by service when it matters most.

word for it, here is what some of our customers had to say about their machines.
