A family of four scrapers has been developed to provide operational versatility while emphasizing physical commonality. The wide variety of operational requirements encountered by scrapers, were considered and related to the basic type of scraper best suited for the particular conditions.

Many vehicle systems were designed to provide maximum commonality between the single and dual engine, open bowl and elevating machines. Various new features were developed to improve vehicle performance and ease of operation.
