Abstract
Abstract A manually operated mobile mixer having a wheeled base and a handle for rolling the base over a supporting surface. A pivot on the base rotatably engages the bottom of a cylindrical mixing container whose exterior surface frictionally engages a pair of wheels on the base. Rolling the base on its wheels rotates the container and mixes materials within the container. The container can be removed and carried to the work area.
