The high-pressure common rail fuel injected engine and electronic power optimizing system (EPOS) provide optimum power and fuel efficiency. Four work modes, auto-idle and machine diagnostics help you manage your fuel costs. For even greater fuel efficiency, auto shutdown helps owners save fuel while the machine isn’t working.

Designed for long life with a robust frame and reinforced superstructure, the DX255LC-5 is built for reliability. Boom and arm bushings and ultra-hard wear disks deliver dependable performance and extended service intervals. The permanently sealed and lubricated track links maximize uptime and reduce operating costs.

A spacious cab means better visibility and more productivity. High-performance air conditioning, extra storage and the reclining, height- and weight-adjustable standard air suspension seat with a headrest and adjustable armrest give you better comfort.
