A foldable utility cart has a hauling body convertible between erected and folded conditions and tiltable between upright hauling and upturned nonhauling positions. Wheels are connected to the hauling body so as to engage the ground and movably support the body when in its erected condition and upright hauling position, but not support the body when in its folded condition and upturned nonhauling position. An auxiliary support carriage is connected to the hauling body and disposable at transport and stored positions respectively when the hauling body is tilted between its upturned nonhauling and upright hauling positions. When the carriage is disposed at its transport position, it is engaged with the ground so as to support the hauling body freestanding without operator assistance in its upturned nonhauling position out of contact with the ground thereby facilitating conversion of the hauling body between its erected and folded conditions and transport of the body to and from a storage location. When the carriage is disposed at its stored position, it is not engaged with the ground and does not support the hauling body.
