MINI EXCAVATORS

KOBELCO minis prove that great things can come in small packages. These machines pack full-size performance into a highly portable frame. A minimal rear swing radius with zero tail overhang allows for excellent handling in confined spaces while a simple design makes routine maintenance easy.

SK28SR-6

  • Engine Power - 17.1 kW (22.9 hp)
  • Operating Weight - 2,790 kg (6,151 lbs)

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 SK28SR while maintaining zero tail swing. No matter what the operation - digging, swinging, loading or dozing - this machine delivers unprecedented performance that will be profitable for owners while fully satisfying the most demanding operator.
