So after working on heavy equipment for several generations as we all know you accumulate lots of parts books, service manuals, and literature. Iv been going through all of ours and organizing it and ran across this book titled “Fundamentals of Earthmoving”. It was put out in 1953 by the Caterpillar tractor company. It is basically some good info and then specs and such of all their equipment produced in that year with some great pictures. My question is has anyone ever seen anything like this one? Didn’t know if it was a very common book that survived or if anyone had ever seen one.
