This is from a new apartment project they were making near me, the huge machine has been a nightmare, causing all sorts of noise, damage, to properties nearby, it was supposed to compound the earth so water wouldnt come back after heavy rains. Those of us affected were delighted to see that the ground was flooded after the last rains, even after all that noise/disruption to our lives. The project has been abandoned, so this guy in the video has found a better use for the dreaded machine.
