 When Robert G. LeTourneau started moving earth in 1919, he thought that land leveling should require only one man. In 1920, by installing a generator and electric motors, R.G. was able to control the scraper blade from the tractor seat while driving the tractor.

 In June 1922, LeTourneau developed his “Mountain Mover” with a telescoping bowl. He incorporated a floor behind the cutting edge taken from his previous designs, and employed welding instead of riveting to save weight.
