Abstract
A manure scraper moves along an alleyway divided into sections by a plurality of gates or partitions and as the scraper passes under each partition, a wire brush or the like attached to the gate but insulated therefrom, engages the upper surface and electrifies the scraper so that an animal touching or being engaged by the scraper, receives an electric shock. The wire brush is connected to a shocking transformer which in turn is connected to a source of electrical energy.
