ABSTRACT:
An apparatus for agitating a fluid that contains a sludge-like material which is stored in an enclosure, such as a pit, storage tank or pond, includes an elongated frame with a motor and a propeller pivotally mounted within a guard at a lower end of the frame, a linkage assembly attached at one end to the motor and the propeller, and a handle pivotally mounted at an upper end of the frame and connected to the other end of the linkage assembly. The motor and propeller are pivotally mounted so that the propeller is pivotable in a generally vertical direction between a first position, generally along the axis of the frame, and a second upward position, angularly displaced from the first position, for directing the agitation caused by the propeller. In addition, the motor and propeller are mounted within the guard so that the propeller is prevented from hitting the floor of the enclosure when the apparatus is rotated about its longitudinal axis.
