Kubota KX057 Series

The Common Rail System (CRS) electronically controls the fuel injection timing and amount in stages rather than all at once for optimal combustion. The results are great efficiency, better fuel economy and less engine noise. Its combination with the Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) Muffler reduces harmful emissions to make the KX057-4 Tier IV-compliant.

Kubota’s original automatic regeneration system automatically burns accumulated particulate matter (soot) in the DPF muffler to keep the muffler clean for longer operation. For safety reasons, automatic regeneration can be turned off with the inhibit switch when the excavator is operating in areas that may pose a fire hazard.

For tough digging applications, use Standard Mode and experience a 4% productivity improvement over the prior model on KX057-4. Activate Eco Mode with the flick of a switch for up to 8% fuel savings over Standard Mode on new KX057-4.
