The King Country Base is the ultimate setup when it comes to rear-mount post rammers. It's very compact and offers 4-way shift so that you can position your post exactly in the right spot. This base is especially popular with farmers and fencing contractors working on steep or uneven terrain where the bigger rotating post driver bases and rear-shift bases aren’t compact enough.

It combines a built-in rear shift on the pivot pin with 150 mm of travel, plus a 500 mm side shift, giving you true 4-way movement. This makes lining up posts faster and easier, even when the tractor can’t be positioned perfectly.

The compact design reduces weight without compromising strength or positioning ability, making it well-suited for hill country work where stability is critical. The simple hydraulic setup is reliable in tough conditions and gives operators fingertip control from the valve bank controls.

No. of additional valves required: 2
