Also, even if the machine did weight 400 lbs, all of that force will not be on the tines alone as some of it will be distributed over the tires as well.
Eh, they are probably referring to the power or capability rating of the hydraulic cylinder itself. It was really kind of an unfair trick question anyhow. But simply claiming 400lbs of down force is a tad misleading.

Obviously it would matter what you are trying to aerate too. Dry clay, moist sand or 6 inches of feathers. I.E The resistance component.
