wheel tractor-scraper

In civil engineering, a wheel tractor-scraper is a piece of heavy equipment used for earthmoving.

A twin engined wheel tractor-scraper has two gas pedals next to each other; one for the front engine and one for the rear engine.

A tower-mounted laser level is used in combination with a sensor on a wheel tractor-scraper in the process of land laser leveling to bring land (for example, an agricultural field) to near-flatness with a slight grade for drainage.

The design of the Fresno Scraper forms the basis of most modern Earthworks (engineering) Wheel tractor-scraper, having the ability to not only scrape and move a quantity of soil, but also to discharge it at a controlled depth, thus quadrupling the volume which could be handled manually.
