Abstract: A crowd gate for urging animals, for example, cows, toward a desired position as, for example, a milking parlor. The crowd gate includes a carriage which is adapted to ride on an overhead track and which swingably mounts a depending gate which may come into contact with an animal standing on a surface underlying the rails. A motor is operative to drive the carriage and, thus, the gate, along the rails until such time as the gate encounters an animal at which time the motor is de-energized for a predetermined time. After the time has elapsed, the motor is again energized until an animal is again engaged. The system also includes a means for elevating the gate and for reversing the carriage motors so that the carriage in the gate may be returned to a starting position.
