Apparatus for splitting in half the breast of a poultry carcass comprising an elongated feed bar on which the carcass can be impaled to have the bar extending through the chicken immediately below the backbone and above the soft breastbone. A cutting blade is supported and rotated in a plane containing the feed bar with the axis of rotation perpendicular to and offset from the feed bar. A toothed conveyor extending along the lengthwise direction of the feed bar is mounted in close adjacency to the feed bar on the side opposite the cutting blade in a position to contact the back of an impaled poultry carcass and propel the carcass along the length of the feed car. An elongated breast support is pivotally supported in alignment with the feed bar for movement in the plane containing the feed bar and cutting blade about a pivotal axis offset from the feed bar on the same side as the cutting blade axis. The breast support pivots between a feeding position, in which the breast support is maintained substantially parallel to and in a spaced relationship to the feed bar to be in contact with the exterior surface of the breast of an impaled carcass as the carcass is moved by the conveyor along the feed bar, and a retracted position, in which the breast support is tilted at an angle downwardly with respect to the feed bar sufficiently to increase the spacing between the feed bar entrance end and the breast support to permit a carcass to be impaled on the feed bar.
