The Challenge 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 front-end 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 Challenge 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.
The Challenge post hole digger requires a third hydraulic control circuit to activate the rotating portion of the attachment; the electric third service feature comes standard with the Challenge CLXâ„¢ series front-end loaders.
