PURPOSE: A control method is provided to reduce fatigue and to easily and efficiently perform excavating and loading work with a bucket. CONSTITUTION: A controller of an angle of a work equipment is composed of: a starting button(34) for automatically excavating, a boom angle detector(40) for detecting a rising angle, a bucket angle detector(41), an electronic proportional control valve(20) for controlling a boom operation valve(13) and a bucket operation valve(14), a controller(25) for outputting a control signal to the electronic proportional control valve. When a user inputs a starting signal by using a starting button for automatically excavating, the controller elevates the boom automatically and controls a bucket(4) for the location of the bucket angle corresponding to the boom angle. Therefore, the loading and the excavating are operated.
