center is disposed in a parallel offset position from the axial engagement line of orientation with the driving source for rotationally driving the auger the shaft body of the auger revolves in an eccentric lateral orbit as the auger rotates which digs the hole by pushing and widening the dirt in the hole rather than cutting and scraping the distal end of the auger has a tapered configuration for initial penetration into the ground the eccentric movement of the shaft body of the auger helps to compact the walls of the hole being dug application_number US 201113272767 A description referring to the drawing figures an embodiment of the inventive auger 10 is generally shown in fig1 auger 10 is adapted for connection to drive unit 12 which is commonly provided by a carrier machine such as a skid steer loader not shown through means generally known to those having skill in the art for example auger attachment may be connected by bolting to drive spindle 14 of drive unit 12 fig1 shows auger collar 15 as a female portion which receives male portion drive spindle 14 hidden from view common drive spindle sizes include but are not limited to 1 u215d inch round 2 inch round 2 9 16 inch round 2 inch hex 2 u00bd inch hex 2 u215d inch hex 4 inch square and 6 inch square the carrier machine provides a means to maneuver the auger into place and applies the hydraulic equipment required to lower the auger into the ground and retract it the drive unit 12 is typically powered hydraulically or through mechanical means with the carrier machine being the source of power the carrier machine can also be a tractor excavator backhoe.
