Kubota D722 Engine Features and Advantages

The Kubota D722 engine is one of the most reliable and efficient power solutions available for compact construction machinery. Known for its advanced engineering and durability, it provides the perfect balance of power, fuel efficiency, and environmental compliance.

The engine delivers a maximum horsepower of 13.7hp / 13.9ps and a maximum power output of 10.2kW, making it a powerful option in the compact machinery category. This high-performance output ensures that mini excavators and skid steer loaders equipped with the D722 can handle demanding tasks with ease.

One of the most impressive aspects of this engine is its rated maximum speed of 2500rpm, which guarantees stable and consistent performance over long hours of operation. This makes it highly suitable for heavy-duty construction sites where continuous, reliable power is essential.

Another key advantage is its compact and lightweight design. With a displacement of only 0.719L and a three-cylinder water-cooled structure, the D722 is small yet powerful. This allows it to be fitted into compact equipment without compromising on strength or efficiency.

Pilot Control System and Operator Comfort

To enhance operator efficiency, modern excavators featuring the Kubota D722 engine are equipped with pilot-operated joysticks. Both walking and operating functions can be controlled simultaneously with two hands, offering smooth and precise movement. This reduces operator fatigue and increases productivity, especially during long shifts.

In addition, the machine is fitted with an advanced control panel. Located on the right armrest box, this integrated multifunctional instrument cluster displays vital information such as vehicle speed, fuel level, oil pressure, voltage, and water temperature alarms. By providing real-time monitoring, operators can ensure timely maintenance and keep the machine in peak working condition.

The ergonomic layout of the control station minimizes strain and allows for comfortable operation. These design improvements demonstrate how performance and comfort go hand in hand, giving operators confidence in every task.

Adjustable Track Width for Flexible Operation

The R15Eco mini excavator, powered by the Kubota D722 engine, takes versatility to the next level with its adjustable track width system. Thanks to a hydraulic mechanism, the track width can be quickly reduced to a compact 900mm, enabling the machine to maneuver effortlessly through tight spaces such as narrow alleys and indoor construction sites.

When wider stability is required, the track width can be expanded to 1200mm in just a few seconds. This flexibility ensures that the excavator adapts to different terrains and working environments without difficulty. The quick-folding dozer blade further enhances the machine’s adaptability, allowing for instant adjustments in confined spaces.

By lowering the blade after adjustment, the ultra-compact excavator can pass through most standard doorways, making it highly practical for indoor demolition, landscaping, and construction projects. This unique feature ensures that operators can maximize efficiency without sacrificing stability or safety.
