Post Hole Diggers

Challenge post hole digger design and features

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.

  • Five models available to best match your tractors’ hydraulic capacity
  • Choose from ten augers and two auger extensions to suit the job
  • All wear parts are easily replaced

Electric third service required…

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 CLX™ series front-end loaders.
