This CAT Earth Mover is loosely based on so-called "Wheel Tractor-Scrapers". This toy model is somewhat based on the 637G Wheel Tractor-Scraper. This behemoth has a loading capacity of 50.0 yd3 [38.2 m3] or 76,000.0 lb [34,473.0 kg]. The top speed of 33 mph [53.1 km/h] provied this beast with enough speed to move its weight of 118,909.0 lb [53,936.2 kg]. Even though the real model is over 31 ft [9.4 m] long, the designers knew how to pack all those muscles into a 1/64th scale model!
The CAT Earth Mover has come out in the following 1/64 scale versions:
