The new Doosan/Daewoo wheel loaders, the DL300 and DL400, feature Tier-3 compliant diesel engines. The DL300 uses the Doosan DL08 engine and the DL400 uses the Cummins QSL9. Both six-cylinder engines feature electronic high-pressure common-rail fuel injection and charge-air cooling.

Number of models: 2

New models: DL300, DL400

Product-line features: The DL300 and DL400 use four-speed, powershift ZF transmissions that can be operated in an automatic mode. The implement hydraulic system for the DL300 employs a tandem vane pump with automatic wear compensation, and the system for the DL400 uses two load-sensing, variable-displacement axial-piston pumps. Both models incorporate hydraulically driven fans.
