This invention is directed to troughs and more particularly to pre-cast or molded troughs made of plastic, fiberglass or other appropriate material and utilizing a novel shape whereby the trough rests on it's natural tipping point using a novel pair of stabilizers made to rest on the ground and fit into corresponding cavities on the underside of the trough to maintain an upright and stable position until tipping is desired. The unique shape makes possible the slight backward tipping of the trough, done easily by one person, so the stabilizers can be kicked away and the trough tipped forward to empty, clean and/or refill.
