Tournadozer Built for Speedy Earthmoving

摘要

Long before the era of the modern skid-steer loader, earthmoving pioneer R.G. LeTourneau invented a rubber-tired dozer capable of much higher speeds than the crawler tractor. Known as the Tournadozer, it was steered by slow-ing or locking the drive wheels on either side, a steering method that became known as the "skid-steer" principle.
