New Dash 11 features

The new Power plus work mode, with enhanced engine/hydraulic pump control efficiency, helps increase productivity up to eight per cent without negatively impacting fuel consumption, compared to the previous models.

The upgraded operator cab is 9 cm wider than current Dash 11 excavator cabs and is OPG Level 1 (ISO 12117-2) compliant with standard OPG Level 2 (ISO 10262) top guard.
