Abstract
A wheelbarrow having two wheels mounted on an axis which is allowed to swivel, thereby allowing the axle to tilt with the terrain while the tray and handles remain substantially level. The wheel assembly is coupled to stop-limits to prevent the excessive tilting of the wheels with respect to the tray and handles.
