My husband does this work. I came here to see how it works . Im greatful for him .this is a hard job.Anyone notice this man back his compactor up to the ledge while also stepping onto a tiny piece of ground with his left foot, leaning over some what off balance over a trench? The ground is always unstable after being disturbed and could of given away.With both hands on the compactor,that would of possibly fallen in as well.
