Over the years LeTourneau has produced some of the world’s largest and most productive rubber-tired wheel loaders, wheel dozers, and haulers, including the world record breaking L-2350 Wheel Loader, the largest of its kind ever produced and offered to the mining industry. So large is the L-2350, it requires the world’s largest tires ever made to carry the massive digging machine. Utilizing state-of-the-art diesel-electric drive systems, LeTourneau machines are at the forefront of today’s most advanced technology being utilized in ultra-large mining rubber-tired loaders and dozers. Focusing on machines designed and built during the time period of 1968 to present, all of the company’s quarry and mining machine offerings, including past LeTro-Loader, LeTro-Dozer, and Titan haul truck designs, as well as current equipment product lines, are featured in great detail Behind the scenes images, as well as model and working views, bring these giants to life with rare historic and modern photography, most of which has never been seen in publication before, making this a must have for all heavy equipment enthusiasts.

Robert Gilmour LeTourneau, the inventor of earthmoving machines, secured nearly 300 patents over the course of his life. During World War II, about 70 percent of the earthmovers and engineering vehicles were his machines that were invaluable to the Allied war effort. With outstanding photography, this overview of 90-years-plus of manufacturing features the company's earliest earthmoving equipment introductions in 1921, all the way up to today's ultra-large mining equipment introductions. This companion book to the three previous publications - R.G. LeTourneau Heavy Equipment: The Mechanical Drive Era 1921-1953, R.G. LeTourneau Heavy Equipment Photo Gallery: The Electric-Drive Era (1953-1970), and Modern LeTourneau Earthmoving Equipment since 1968 - includes updated information and all new images of the LeTourneau enterprise.

Explores soil as a nexus for water, chemicals, and biologically coupled nutrient cycling Soil is a narrow but critically important zone on Earth's surface. It is the interface for water and carbon recycling from above and part of the cycling of sediment and rock from below. Hydrogeology, Chemical Weathering, and Soil Formation places chemical weathering and soil formation in its geological, climatological, biological and hydrological perspective. Volume highlights include: The evolution of soils over 3.25 billion years Basic processes contributing to soil formation How chemical weathering and soil formation relate to water and energy fluxes The role of pedogenesis in geomorphology Relationships between climate soils and biota Soils, aeolian deposits, and crusts as geologic dating tools Impacts of land-use change on soils The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Editors

In the history of heavy equipment development, no single man’s name is more respected or revered as that of R. G. LeTourneau. Robert Gilmour LeTourneau is considered by many to be the dean of high-speed mobile earthmoving equipment. His designs of the 1920s, 30s, and 40s laid the fundamental groundwork for many of the earthmoving machines we see today. Self-propelled, rubber tired scrapers, bulldozing blades, and rippers were all conceived under his engineering genius in the quest for moving material at the lowest-cost-per-yard. The time period of 1953 to 1971 saw many more innovative machine and engineering achievements 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, help showcase what made R. G. LeTourneau so important in the heavy equipment industry.
