Mustang’s new excavator lineup is supplied by Yanmar, and consists of models 170Z, 270Z, 350Z, 450Z and 800Z. The excavators are zero-tail-swing models, eliminating cab overhang beyond the tracks in all directions. The hydraulic system incorporates two variable pumps and two gear pumps. The oil flows are combined and redirected to where the flow is needed. High-strength booms are built with a single boom-pin design with internally routed hydraulic lines. Crawler tracks are offset for stability and smooth travel.
