Intended Use
The 6" Post Hole Digger (#51478), the 9" Post Hole Digger (#51479), and the 12" Post Hole Digger
(#51480) are PTO driven. The aggressive cast-steel, split-tip, auger rips through tough, compacted
soil. The strong, durable design includes a number of safety features. In addition to an integrated
safety shield, the Quik-Tach® threaded auger design is safer than a bolt-on auger, and the butterfly
flighting’s rounded edges make it safer than spiral flighting.
