A device mounted above a cow in its stall for causing the animal to move rearwardly by applying pressure to its shoulders when the animal arches its back for the purpose of defecating or urinating. By moving rearwardly, the animal's droppings will be deposited in the stall's gutter. The device includes a pair of spaced rod members interconnected by a connecting rod. One of the rod members has an integral elongated bar at its lower end situated horizontally above the animal's shoulders and extends normal to the stall's length. The connecting rod includes pivot shafts on each end with each supporting a pair of knob-controlled mating clutch members for manually effecting their release and binding engagement. Manual control of the clutch members permits the rod members and connecting rod to readily located the elongated bar in any desired position.
