The Universal Engineer Tractor: A High Speed Tracked Vehicle with Low Speed, High Drawbar Performance

The U. S. Army is presently developing an unusual tracked vehicle--the Universal Engineer Tractor. It is suitable for use as a bulldozer, scraper, rough grader, prime mover, dump truck, cargo carrier, and armor-protected personnel carrier. Its design features a hydropneumatic suspension system, a high speed-high drawbar track, a special broad range transmission system, the use of lightweight materisls, a front scraper bowl with positive type ejection, and a flat track suspension with rear drive sprockets. This paper describes the requirement, background, operations, and components of the Universal Engineer Tractor.
