In the 28-33 metric ton size class, few machines match the DX300LC-5. It has the horsepower to tackle larger projects, but is designed to keep fuel and maintenance costs low.

Its high-pressure common rail fuel injected engine teams with the electronic power optimizing system (EPOS) provide optimum power and fuel efficiency. Choose between four work modes, auto-idle and machine diagnostics. For further fuel savings, auto shutdown helps owners save fuel during non-working conditions.

Designed for long life with a robust frame and reinforced superstructure, the DX300LC-5 is built for reliability. Boom and arm bushings and ultra-hard wear disks are designed for extended service intervals and steady performance. The permanently sealed and lubricated track links maximize uptime and reduce operating costs.

Work naturally inside the cab with controls that are placed where you need them. Easily control machine functions with comfortable joysticks. Change between ISO to BHL control patterns. Select the correct auxiliary flow rate using a switch on the control pattern.
