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.
