Abstract
A self-leveling mixer apparatus includes a base and a generally downwardly tapered movable mixing tub supported from the base in a manner such that the tub is movable between first and second positions relative to the base. A leveling valve is provided for controlling a level of fluid in the movable mixing tub. A connector linkage is operably associated with the mixing tub and the leveling valve for adjusting the leveling valve in response to movement of the mixing tube relative to the base. A rotating mechanical agitator is disposed within the tub for inducing a generally vortex type of fluid flow pattern within the generally downward tapered tub.
