US Patent:

42665108, May 12, 1981

Filed:

Jan 11, 1980

Appl. No.:

6/111360

Inventors:

Robert A. Rowan - Enigma GA
Leroy Mathis - Enigma GA

International Classification:

A01K 500

US Classification:

119 51R

Abstract:

Juxtaposed pairs of upright portable bunker wall sections are erected on level ground in longitudinal alignment and tied together and braced by a system of adjustable and portable bracing units along the length of the elongated open ended and open top silage bunker thus formed. The bunker is filled with silage up to a proper level by a mobile loading machine with the formation of the silage bunk progressing rearwardly. As the silage bunk is thus formed, the forwardmost bunker wall sections are shifted to the rear end of the bunker to enable the formation of a uniform depth silage bunk of any desired length. As bunker wall sections are removed, the formed or molded silage bunk is covered and protected by a dark plastic film. A controlled feeding barrier is employed at one or both ends of the silage bunk including side parallel guide units on skids which straddle the opposite sides of the bunk and a transverse feeding gate which slides forwardly on the guide units in response to pressure exerted on the gate by animals feeding on one or both ends of the silage bunk.

Abstract:

A turnplow and a subsoiler are attached to a common draft beam with the subsoiler pivotally mounted and counter-weighted so that lifting of the implement will cause automatic retraction of the subsoiler relative to the turnplow. A drag point on the subsoiler engages the ground when the implement is lowered and thereby moves the subsoiler to an active position below the turnplow. Simplicity of construction is featured.

Abstract:

A high capacity wagon for silage and the like has a gravity-assisted rear inclined dumping wall with high ground clearance in both the full open and all intermediate positions. A simplified positive latch mechanism for the dumping wall is biased in the latching position and easily released by the operator of a towing tractor. The necessity for tilting the entire body of the wagon to completely dump its contents is eliminated.
