The Kubota KX057-4 is the most powerful mini excavator in the Kubota lineup, designed for those who need superior digging power and working depth without sacrificing the maneuverability typical of compact machines.

With an operating weight of approximately 5.5 tons, it sits at the upper end of the mini category, offering midi-class performance in a size that can still be transported on a light trailer.

Key Operational Features

• Kubota V2607-DI direct-injection engine: 46 hp with constant torque, designed to maximize penetration force in both normal conditions and in compacted soil or roots.
• 3-pump Load Sensing hydraulic system: ensures smooth combined movements and fuel consumption proportional to actual operational demand.
• Two auxiliary circuits with proportional control (SP1 and SP2): oil flow is digitally adjustable and preset to 5 levels based on the attached equipment—no tools required.
• Auto-shift system: travel speed automatically adapts to ground conditions, shifting from fast to slow based on resistance encountered.
• ROPS/OPG cab with digital panel: ample legroom, cushioned seat, 3 rearview mirrors, operation logging system for up to 90 days, and genuine Kubota anti-theft system.

Who It’s For

It is the right choice for companies and operators working on medium-sized job sites—roads, infrastructure, foundations, deep excavations—where productivity matters as much as precision. It makes particular sense for those who want a versatile machine with multiple attachments, thanks to the digital control of the dual auxiliary circuit.
