Adapters for auger drive shaft

A drive shaft (20) permits driving two different driven shafts, such as those used on powered earth augers, from a single power source, whether the driven shaft has a circular cross section drive coupling, or a hexagonal cross section drive coupling. In one form an adapter (50) can be slipped over a...

Beschreibung
Zusammenfassung:	A drive shaft (20) permits driving two different driven shafts, such as those used on powered earth augers, from a single power source, whether the driven shaft has a circular cross section drive coupling, or a hexagonal cross section drive coupling. In one form an adapter (50) can be slipped over a hexagonal shaft to receive a circular cross section drive coupling, and in another form, a shaft is provided with two axially displaced portions. An outer end portion has a hexagonal cross section, and a slightly larger circular cross section shaft portion is positioned adjacent the power unit.
