I have two arms, but fingers none. I have two feet, but cannot run. I carry well, but I have found I carry best with my feet off the ground. What am I?

Why this works

This riddle plays on the double meanings of "arms" and "feet." A wheelbarrow has two handles that are often referred to as "arms," but they don't have fingers like a human arm does. The "two feet" refer to the support legs of the wheelbarrow, which allow it to stand when not in use, but it cannot run. The clever twist comes in the line about carrying best with its feet off the ground—this indicates that the wheelbarrow is most effective when lifted by its handles, allowing it to transport items easily.
