Post Drivers | The FencePro Ultra G2S
Professional-Grade Post Rammer Performance with Ultra-Smooth Operation
The FencePro Ultra G2S post driver is a professional-grade hydraulic post rammer built for fencing contractors and large-scale farmers who want proven performance, refined operation, and long-term reliability from their rural fencing equipment. Sitting at the core of the FencePro Ultra Series, the Ultra G2S builds on one of the most successful post driver units ever used in New Zealand, the original Ultra G2, and refines it with meaningful design improvements focused on smoothness, efficiency, and increased service life.
Designed and manufactured in Palmerston North, New Zealand, the Ultra G2S delivers a level of performance that suits a wide range of professional users. Its highly configurable design means it can be set up as something like a side mounted post rammer on a tractor or built into a fully spec’d contractor machine with advanced bases like the RB800 180° rotating base and the full range of FencePro post banger attachments.

Structurally, the Ultra G2S is built around FencePro’s specially rolled 350-grade Australian steel mast, delivering excellent durability. A massive 75 mm greasable mast pivot pin, heavy-duty hydraulic hinge system, twin-skinned adjustable feet, and replaceable wear points throughout the machine reflect the same contractor-grade design found across the FencePro Ultra Series of post drivers. This is a machine built to be reliable and perform at a high level, even after years of hard work.
Some of the unique product features on the Ultra G2S is FencePro’s Ultra ActiveBlock® system and UltraGlide mast shift, both engineered to reduce friction and maximise your fencing efficiency. Unlike traditional post hitters, the Ultra G2S uses low-friction nylon wear surfaces within the block and all of the mast. This allows the block to fall faster, increasing impact force and driving performance, while also reducing the wear on your mast. The machine doesn’t just feel smoother, it actually delivers more effective hitting power. Smooth is fast.

A large 330 mm single top pulley ensures smoother rope travel, while the Ultra ActiveBlock® design effectively eliminates rope whip. This significantly improves safety and extends rope life. Over time, this results in lower running costs and a post rammer that stays tighter and smooth to use for longer.
In rural fencing conditions, the Ultra G2S offers excellent hydraulic post rammer control. With 27 degrees of hydraulic side tilt and a 35-degree hydraulic top link range, operators can maintain straight fence lines across hill country and uneven terrain. Its stability and smooth mast control also make it a popular choice for applications like mounting to bulldozers and purpose-built tracked fencing machines.
As standard, the Ultra G2S is supplied with a 270 kg Ultra ActiveBlock®, delivering strong all-round performance for everyday fencing. For those working in harder ground or wanting additional impact, the machine can be upgraded to a 300 kg Ultra ActiveBlock®. Alternatively, the machine can be specified with a standard 270 kg block in place of the ActiveBlock®, giving buyers flexibility to configure the post driver to suit their operation.
The standard post driver mast height is 4.5 metres (giving you 3.7 metres under the post cap), but the Ultra G2S can also be upgraded to a 4.8-metre mast for additional height and hitting power when required.
Like all post drivers in the FencePro Ultra Series, the G2S is built around FencePro’s Modular MBA system, allowing post rammer bases and attachments to be added or changed at point. This means the machine can start life as a more basic post rammer and later be upgraded with options such as the RB800 180-degree rotating base, the UltraGlide Rockspike extractor system, auger kits, and other productivity-enhancing accessories. However if you want to spec your full setup from the factory, that is the most common option.
The Ultra G2S represents the evolution of one of the most trusted post driver designs in the country. The original Ultra G2 earned its reputation by being tough, reliable, and user-friendly, and the G2S builds on that legacy with improvements that make it smoother, more efficient, and even more durable.
