Abstract: An apparatus for automatically processing an animal carcass (8). Suspension means (122, 123) suspends the carcass (8) in an inverted position with the spine inclined upwardly towards the neck (11) with the spine located beneath the carcass (8) and so that the diaphragm (119) is approximately vertical. A cutting assembly, (130) moves into the abdominal cavity adjacent to the diaphragm (119), and a cutting means (28) cuts the diaphragm (119) around the periphery. A brisket shearing means (21) cuts the brisket (20) with a shearing action along the brisket (20) from the abdomen and towards the neck end of the brisket (20). The reaction member (188) is pivotally movable relative to the brisket (20) about a rear end to generally follow the contours of the brisket (20).
