The DX420LC-3 has all the features and capabilities to handle road building, site development, oil and gas pipeline development, and other construction applications.

The DX420LC-3 is powered by a 6-cylinder 362-hp water-cooled diesel engine that has been optimized for use with a cooled exhaust gas recirculation (CEGR) system, a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF). Engines with this configuration are optimized to reduce nitrogen oxides (NOX), and after-treatment is needed to reduce particulate matter in compliance with iT4 emission regulations. The turbocharged engine features a high-pressure common-rail design with direct fuel injection, electronic control and four valves per cylinder.
