That has to be one of the best machine operators I have ever seen. The laborers must love working with this operator.Even though Korea is a small country, speaking of human resources, especially in terms of technology, it's extraordinary.The clip must end before the excavator and its operator pick up a toothbrush and tube of toothpaste and brush the supervisor's teeth after lunch! This is impressive.He is already the most famous excavator driver in Korea. I can't help but admire his driving. I hope many foreigners can watch this video and spread Korea's excavator technology!
