Ditch Witch introduces the MX family of five mini-excavators, which achieves true zero tail swing with removable counterweights. The patented closed load sensing system (CLSS) allows precise control through all levels of operation. A pilot-operated control valve provides smooth-operating hydraulics. Thanks to full-circle operator-station rotation and pivoting-boom design, the excavators can easily dig around obstacles. Models range in size from 1,960 to 10,300 pounds with digging capabilities from 4 feet 11 inches to 13 feet deep. The line is sold and serviced through the company's worldwide dealer organization. Estimated list prices: $16,000 to $50,000.
