Features

CLEAN, EFFICIENT, POWERFUL KUBOTA DIESEL ENGINE

Kubota excavators feature proven Kubota diesel engines. Performance matched to each excavator, they provide dependable power at low sound levels with the highest fuel efficiency while meeting emissions standards. In cold weather, the super glow preheat system ensures engine starts as low as -20°C in 10 seconds! Easily accessible dual element air cleaners provide extra protection in the toughest conditions. And an electric fuel pump automatically bleeds the fuel lines should the fuel run out.
