A head gate for immobilizing the head of a calf in a portable calf chute, includes one pivotal side bar and a second side bar mounted to pivot and slide axially. A top bar is rigidly carried on the second side bar. A linkage is operated by an overcenter handle to open and close the head gate. When closed, the side bars of the head gate trap the neck of the calf and the top bar pushes the head downwardly. A tension spring acts to hold the head gate open. A locking rod may be inserted in one of the side bars and hooked on a pin to secure the head gate in the open position when the calf chute is being moved between different locations.
