Abstract: A system for removing the neck, windpipe and esophagus from poultry where the neck is broken with an opening through the neck skin at the break which includes a neck removal machine and a pulling machine past which the poultry is moved on an overhead conveyor. The neck removal machine holds the windpipe and esophagus at the neck break and engages the broken end of the neck with a finger member to displace the neck from the poultry to break the neck skin and release the neck while leaving the windpipe and esophagus intact. The pulling machine engages the windpipe and esophagus to pull them out of the poultry carcass which also removes any crop still attached to the esophagus.
