<p>STACK FORMER A towable wheel mounted frame structure for receiving blown roughage materials such as corn and hay silage, dry hay, corn stalks and the like serves as a form to create a stack of silage formed directly on the ground. The frame is hydraulically foldable into an efficiently compact form for transportation through gates and over bridges and roads and is hydraulically expandable to provide relatively wide, outwardly sloping closed sides with an open bottom and open ends for stacking operation. A separate frame associated foldable closed top is cable operated between the contracted and expanded positions of the frame and hingedly arranged frame supported baffle sections are movable from closed position for road travel to stack forming position where they form an enlarged baffle depending from the top of the expanded frame between the sides to intercept blown roughage and cause it to fill the confined area of the former.</p> |
