We introduce a large scaled 6 legged walking machine. It was developed to realize a solid and reliable walking vehicle for practical uses in forestry steep terrain with spread mechanical elements those used in usual construction machines. It weighs about 4,000[kg] with aluminum structure. Owing to a mounted diesel engine of output 11[kW] and hydraulic drive systems, it can walk around on a soft soil terrain and climb the steep slope of inclination up to about 30[deg], and walk along contour line of lateral inclination up to about 40[deg]. Finally it walked and worked well, despite it was tested on severe steep terrain where a lot of shrubs and stumps exist.
