A livestock head splitting apparatus of a rotary type rotates a plurality of head trays and respective blades sequentially through loading, head-splitting and discharge stations spaced around the shaft, and in a head splitting mode, drives each head tray and blade relatively toward one another in the head splitting station. In a unique cleaning mode, the trays and blades are instead kept apart throughout the rotation to maximize the exposure of each tray to a spray of cleaning fluid directed into the apparatus. A computerized control system cooperates with an electric motor to drive the rotation and give a degree of user-control over operational aspects of the motor, such as the running speed of the apparatus in the cleaning and head splitting modes and a jogging speed of the apparatus used to index the head trays to desirable locations.
