Abstract
A portable mixer for use for use with an open top mixing container for mixing concrete or the like as having a pair of inboard rotary mixing blades and a pair of outboard mixing blade assemblies mounted on a generally horizontal rotary shaft. The outboard mixing blades are made up of a central hub removably affixed to the shaft. A peripheral ring extends about the hub and is connected to by a plurality of spokes. The peripheral ring has a diameter greater than that of the intermediate blades in order to prevent the intermediate blades from engaging the mixing container. A plurality of rotary disc blades are pivotally mounted on one of the plurality of spokes. The rotary disc blades have a diameter sufficiently large to cause a portion of the rotary disc blades to extend outwardly beyond the peripheral ring in order to engage the mixing container sidewalls.
