ABSTRACT:
A hog head is removed by suspending the carcass in a head-down position, marking the skin of the carcass around the neck, engaging a hook in the jaw of the carcass and applying force to the hook to rotate the head upwardly, and disengage the atlas joint whereby the head is substantially removed from the carcass. Continuous apparatus includes head pulling structure running parallel to and synchronized with the carcass suspension system, and preferably horizontally offset therefrom, so that the carcass assumes a "bellydown" attitude when head-pulling force is applied thereto. Semi-continuous apparatus may apply the required force using a flywheel, a crank, a lever or a fluid driven cylinder.
