The work rate of the hydraulic excavator is directly linked to the performance of its operator. We have designed the DX300LCA by putting the operator at the center of its development goals. The result is significant ergonomic value that improves the efficiency and safety of the operator.


This hydraulic excavator is equipped with an air-to-air intercooler engine with the greatest power output in its class and excellent fuel economy. Equipped with the e-EPOS system, the new and improved version of EPOS SYSTEM, it assures outstanding workability, productivity, and operational efficiency while decreasing fuel consumption.

Reliability & Maintenance

Short maintenance operations at long intervals increase the on-site availability of heavy equipment. We have developed the DX300LCA with a view to creating even higher productivity and profitability for the user.
