The Cat 973 Family Includes

973, 973C, 973D & 973K

Caterpillar 973 Crawler Loader

The Cat 973 was introduced in 1982, and featured a 3306 direct injection turbocharged, six-cylinder engine producing 210 flywheel horsepower (FWHP) with a hydrostatic transmission. It came standard with an electronic monitoring system, sealed and lubricated tracks, an oscillating undercarriage, and a Z-bar linkage. In 1999, it was replaced by the Caterpillar 973C crawler loader, increasing horsepower to 230 FWHP. The 973D followed, adding 10% more horsepower than C-series, better fuel efficiency and reduced wear, working at the point of combustion to optimize engine performance and provide low exhaust emissions. Compared to the 973D, the 973K offers a more fuel efficient Cat® C9.3 ACERT™ engine and Eco Mode combine to give you a 10-25 percent reduction in fuel use. The oscillating undercarriage decreases ground shock for increased stability and smoother ride. Heavy Duty track standard for aggressive applications like land clearing, side-slopes or rocky terrain.

When maintained with our high-quality undercarriage parts, these Cat 973 crawler loaders can stay on the job for a long time. Order your components from us to help extend the life of your Cat 973 crawler loader.
