LEGO 9686 Machine&Mechnism - 13. Excavator

Excavator made with LEGO 9686 Machine&Mechnism. I tried to make the part that can move to the maximum possible. The valve switch was used to move the arm of the excavator and the turntable function was added to make it turnable. The shovel is not so easy that I can not pick it up and throw it away; I’ll have to make it better next time.
