Post Hole Diggers

The post hole digger includes a carriage and drive unit; optional augers are available in 10 different sizes.

The hydraulic post hole digger drive unit is operated by a third service from the front end loader to drive whichever size auger is fitted. The operator controls the loader arms to provide downward pressure while drilling the hole, or by raising the loader arms to lift the auger out of the hole.

The post hole digger is supplied with a one piece attachment carriage. The drive unit can be positioned to the left, right or centre of the carriage to suit individual needs.

There are a number of drive units to best match the tractor's hydraulic capacity and auger sizes to suit any job. All augers come standard with replaceable tungsten carbide cutting teeth and pilot.
