A light weight, inexpensive rotary drum mixing device is provided in which an essentially pear shaped drum, open at the small end and having an axially elongated socket protruding from the large end, is rotatably supported on a unitary base having a transversely extended forward end and an upwardly and angularly extending rear end providing a bearing portion detachably engageable with said socket to rotatably support the drum at an inclination of about 35 DEG , readily engageable means on the bearing portion and socket for preventing unintended axial movement, the forward end of the frame being slightly forward of the center of gravity of the rotatably supported drum to firmly support the same as drum contents are being mixed by rotation of the drum, and providing a pivot fulcrum for tilting the assemblage to discharge contents of the drum, and means externally of the drum facilitating application of circumferential force to impart controlled rotation to the drum. The drum has a plurality of axially extending radial fins for lifting contents in rotation thereof and is preferably fashioned from molded plastic material either as a unitary body or as a plurality of interfitting sectors joined together at said ribs. In its simplest form the device has protruding means circumferentially of the drum for hand engagement to impart rotary movement to the drum; but when the device is intended for repeated and extended use the drum base is preferably provided with a circumferential gear slidably engageable with the drive gear of mechanical drive means fixedly mounted to said frame, on support means integral with the frame and disposed above and parallel to said bearing portion.
