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] provided this beast with enough speed to move its weight of 118,909.0 lb [53,936.2 kg]. Even though the real vehicle is over 31 ft [9.4 m] long, the designers knew how to scale-down and pack all those muscles into a regular Hot Wheels blister!
CAT Earth Mover was also issued as a Matchbox model called Scraper seen here. What first was a Hot Wheels casting, that later made an appearance under the Matchbox line, eventually saw a retooling in 2008 under the same Matchbox name "Scraper"

From the back of the 1996-card:
There have been over 10 different SOL-AIRE™ CX-4 models made since its introduction in 1984. Among these, the "California Custom" model with the light blue base is most highy prized by collectors.
