Western Wheeled Scraper Company, Manufacturer
It consists of a scraper blade suspended from a frame, which is mounted on four wheels. The blade is hung so that it can be placed at any angle, horizontally or vertically. It is adjusted horizontally by means of a circle and adjusted vertically by the wheel operated gear lifts. A simple mechanism allows the frame to be shifted across the axle, allowing one wheel to run alongside a ditch when making a cut. The rear axle is pivoted in the centre, so that the rear wheels may be inclined in either direction to counteract the side draft.
It was usually pulled by a team of four to six horses, although it could also be pulled by a traction engine when used on especially hard soil etc.
The scraper grading is operated by making successive shallow cuts and gradually working the excavated material from a lower to higher elevation.
