With capacity of 38 tonnes (42 ton), offers proven reliability, durability, high productivity, superior operator comfort and lower operating costs. With a focus on unique, adaptable productivity, the 740C EJ has many updated and improved features, an all new powertrain and new ease of operation features including Automatic Retarder Control.

  • Improved fluid efficiency of up to 5% improvement over Tier 4 Interim/Stage IIIB products (including Diesel Exhaust Fluid consumption).
  • High machine performance across a variety of applications.
  • Enhanced reliability through commonality and simplicity of design.
  • Minimized impact of Emission Systems: designed to be transparent to the operator without requiring interaction.
  • Durable designs with long life to overhaul.
  • Delivering better fuel economy with minimized maintenance costs while providing the same great power and response.

Advanced MEUI™-C Injector

Advanced MEUI-C injector platforms deliver increased injection pressures and more precise fuel rates. These durable injectors enhance responsiveness while controlling soot.

Innovative Air Management

Cat Tier 4 Final engines feature innovative air-management systems that optimize airflow and enhance power, efficiency and reliability.

Diesel Exhaust Fluid (DEF)

Cat engines equipped with a Selective Catalytic Reduction (SCR) system inject Diesel Exhaust Fluid (DEF) into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5% high purity chemical grade urea and 67.5% de-ionized water.

Engine Compression Brake

The engine compression brake improves retarding response and increases retarding power for controlled descent of grades.
