The hydraulic excavator is used at a wide variety of sites. Its diversity and convenient operating nature make it popular. Among the different types of work performed by hydraulic excavators, level digging work accounts for a large percentage. When digging or finishing ground surfaces level using the backhoe front attachment, the boom tip height must be controlled so that the bucket tooth tip can be moved horizontally. This paper describes a method of automated level digging control we wish to propose. By using this control system, depth controlled digging can be achieved in the same way as usual manual lever operation while minimizing repetitive depth confirmation work, thereby raising the working efficiency level.
