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 operably associated with the tub and the leveling valve is connected therebetween for adjusting the leveling valve in response to movement of the mixing tub relative to the base. The tub preferably has a generally oval shaped upper end and a generally circular shaped lower end and is constantly tapered therebetween. A tub orientation control linkage is provided to prevent tilting of the tub as it moves between its upper and lower positions.
