Mini excavators are the machine of choice for small jobs where space is limited, like garden construction and pipe laying. In addition to their minimized tail swing radius, minis have also developed excellent performance characteristics and maneuverability that have broadened their usefulness for many different types of jobs.

Now, KOBELCO has taken the next evolutionary step by packing even more digging power and practical performance features into the new SR-5 Series while maintaining zero tail swing. No matter what the operation-digging, swinging, loading or dozing-these machines deliver unprecedented performance that will be profitable for owners while fully satisfying the most demanding operator. The SR-5 Series offers further refinement of the reliable mechanisms that have earned KOBELCO a reputation for excellence around the world. But that's not all. Our engineers have also kept the environment in mind when developing their designs, ensuring that the SR-5 machines pass all of the atest exhaust-gas regulations. Thanks to KOBELCO, mini excavators have just taken an evolutionary leap forward, with more powerful performance packed into less space than ever before.
