Given a wheelbarrow that has two wheels side by side (as opposed the normal

Is it better to pull or push a wheelbarrow, assuming that it is loaded so as
much of the weight is over the axle, with a little more on the side closer
to the handle. By "pull" I mean walking forwards, towing the barrow behind
me with hands level with buttocks, not facing the barrow and walking
backwards!

Pulling is always more efficient. If you push, the force will
generally have a downwards component which contributes nothing to the
forward movement of the barrow.
