Abstract
An auger attachment system having a collar combined with an auger and one or more couplers each having a first end and a second end. The coupler first end is adapted to operatively combine with the output drive shaft of an engine suitable for rotating an auger. Each coupler has a different size and/or geometry at their respective first ends to allow each coupler to combine with a drive shaft having the corresponding size and geometry. The coupler second end is adapted to combine with the collar thereby allowing a single auger to be used with multiple drive shafts, each having a different size and/or geometry.
