Not only is the thumbnail a clickbait, but a bunch of the machines in this video are shown multiple times. If not the same machine, it's just a different model or brand of the same function.Just imagine how many millions of man hours it would take to work the land with shovel & bucket, a single machine can do all of them and faster. We are blessed to have smart engineers in the world.Construction sites wouldnt be the same without the powerful presence of heavy equipment machines.
