Cattle stanchion apparatus in which a plurality of fixed and release stanchions define a row of head openings for animals, the release stanchions tending to pivot to open positions. Latches at the upper extremities of the release stanchions are engageable by couplers carried by a rotatable and axially movable positioner. An operating mechanism is actuable to axially move the positioner, and a locking system is actuable to rotate the positioner and thereby move the couplers into and out of a path of engagement with the latches of the release stanchions. The arrangement gives the operator the capability of moving all of the release stanchions to closed positions to lock the animals in the feeding stalls, or allowing the animals individually to actuate the system to lock themselves in, or allowing the animals to enter and leave the stalls as they wish. The locking system can be placed in a locked position to disable the operating mechanism. A variation of the locking system permits it to be locked against inadvertent movement from either its locked position or its unlocked position.
