Abstract: A cover for a wheelbarrow having a central region with a frame extending outwardly therefrom. A flexible gasket is provided on an interior surface of the frame and contacts the wheelbarrow's rim when the cover is set in place. Securement assemblies are engaged to lock the cover to the wheelbarrow and this deforms the gasket, thus providing a watertight seal between the cover and wheelbarrow. A hole is defined in the central region of the cover and a tubular member extends therethrough. A detachable cap is engaged with the tubular member to selectively close off access to the interior cavity of the wheelbarrow. A tether keeps the cap engaged with the cover. The cap may be removed to allow a pipe to be inserted into the interior cavity to pump liquid into or out of the wheelbarrow.
