The three most important parameters of excavator are operation weight (quality), engine power and bucket bucket capacity.

Q: I see also many human remains in Europe and Asia..Sinanthropus Pekinensis and others..: No, it's not silly. You ignore TIME as a variable. We carry within us the history of Human Origins. Our DNA, and the variation we see within it in the world, shows us humans evolved in Africa over 200,000 years ago, and moved out of Africa at least 60,000 years ago.

Q: I need to dig up about 400 cubic feet of earth from my backyard (we are moving a retaining wall), and doing it with a shovel doesn't sound very attractive. I can't get a Bobcat or an excavator to the backyard because we are on a hill, meaning 1) there are stairs leading to the backyard and 2) the passageway between the house and the fence is too narrow. So it needs to be some lightweight tool. I don't mind working in the backyard, just don't want to do it by hand.If no tools exist and we'll have to hire day laborers to shovel the soil, how much earth can 1 person reasonably shovel in an hour? We'll need this to estimate the cost.Thanks!!: 1.) Use a powered post hole digger to drill a seies of hole and then shovel out the loose soil. Or use a garger tiller to loosen the soil. 2.) There is an old fashned device called a slip shovel. Its like the blade of a dozer but is uses cable to move it. 3.). Use a high pressure hose to turn the solid into mud/sludege and use a pup to lift it out. Mkae sure you have a place to put the slurry.
