Robert Gilmour LeTourneau is considered by many to be the dean of high-speed mobile earthmoving equipment. The time period of 1953 to 1971 saw many of R. G. LeTourneau's most innovative and spectacular heavy-equipment designs in the fields of earth-moving, off-shore oil exploration, logging, and defense. This second volume of fantastic machine creations covers the later years up until the sale of the company to Marathon in 1971. Standard production, specials, and experimental machines are shown in rare archival images, some being shown in print for the very first time.
