This Caterpillar Modern Earthmoving Handbook was originally printed in the 1950s. It was an excellent guide to machine operators illustrating in detail the methods used in making culverts, stump removal, cutting slopes, rock ripping, pushloading scrapers and other earthmoving techniques involved with road construction.  Comprehensive descriptions are shown in cartoon-style layouts.  An excellent booklet showing many Caterpillar machines in action including D7s, D8s, DW21s, scrapers and graders. This is a reprint from the restored original, with semi-gloss covers and high quality paper throughout - 24 pages in total.
