Abstract
An auger for digging holes in soil is coupled to a gearbox and powered by the power take-off of a tractor. The auger comprises a shaft with a cutting head disposed near its bottom end. The cutting head comprises a plurality of cutting (i.e. digging) blades that cut into soil. Flighting disposed above the cutting head moves and lightens soil, but the flighting does not extend far above the cutting head. The majority of the shaft is free from protrusions that may ensnare a user of the auger during use.
