Posted By Equipment World Staff On November 14, 2007 @ 12:00 am In Boomerang | No Comments

Top Performance. A machine designed to be productive over a wide range of tough applications from heavy clearing to high-volume truck loading, from the slag pits of steel mills to big city landfills. The 973C not only can master the toughest excavation but can also finish grade with delicate precision. Reliable, durable, rugged construction, self-diagnosis of electrical and power train systems, and easy maintenance help ensure extended service life.
