The Kinghitter Series 1 postdriver design includes many of the innovations that Kinghitter is famous for.

It is a fully hydraulically operated tractor mounted post driver, not just ideal for larger life style blocks, small beef and dairy farm operations, but capable of tackling difficult fence lines with ease. There would be more fences constructed in New Zealand by a Series 1 than any other post banger by far.

The versatile machine that slots seemlessly into the Kinghitter range of postdrivers.  The Series 1 is strong and durable, superior to any other postdriver in the field today. This is a testament to the proven design and simple operation that Kinghitter owners and operators have enjoyed for over 40 years.

All the features of the series 1-400 postdriver with the addition of the Kinghitter Terminator sidemount base. This Combo is truly versatile with 950mm of sideways travel, the large toolbox, and tool holders for your level, spade, spinning jenny, and hand rammer.

Tow a trailer behind with the tow bar if required. The counterweight on the left side under the toolbox balances out the mast weight so the rig is stable on uneven ground. The base can be removed at any time so the post driver reverts to a rear mount. There may be some situations where the tractor must straddle the guide wire if the bulldozed line is narrow.
