Imagine a compact machine transitioning effortlessly from a quiet, zero-emission electric mode suitable for indoor use to a powerful diesel mode for outdoor heavy-duty tasks—this flexibility is a cornerstone of its design.

Cutting-Edge Engine and Hydraulic System

At the heart of the 300.9D VPS lies a robust Yanmar 3TNV70 engine. This liquid-cooled, three-cylinder diesel engine delivers 13 horsepower (9.7 kW), meeting stringent U.S. EPA Tier 4 Final and EU Stage V emission standards. Those working with the electric HPU300 variant benefit from a 3-phase electric motor outputting up to 12 hp (9 kW) in North America, which ensures silent operation and zero emissions.

The hydraulic system is designed for precision and power, featuring a gear pump with a flow rate of 6 gallons per minute (22 l/min) and operating pressure of up to 2,466 psi (170 bar) at the front linkage and travel functions. The swing gear operates at 1,015 psi (70 bar). This hydraulic performance guarantees smooth and responsive control during digging, lifting, and other tasks.

Exceptional Maneuverability and Stability

The mini excavator’s extending undercarriage and fold-out dozer blade enhance both stability and performance. Operators can easily retract the undercarriage from the comfort of the seat, allowing the machine to fit through tight openings without sacrificing working stability once extended. The foldable ROPS (Roll-Over Protective Structure) safety frame is another thoughtful feature that allows the machine to be transported or stored with minimal hassle while providing robust operator protection during operation.
