Abstract: The invention comprises an apparatus for clearing range land of sagebrush an other invading non-grazing plant species. The device is adapted to be towed by a tractor, and has a pair of blades arranged in a "V" configuration, with the point of the "V" facing forward. The device is adapted to float on the ground surface so as to not bind on immovable embedded objects. Removable knife blades on the lower, ground-engaging surfaces of the blades shear off or pull out brush. A roller having roller blades on the surface mulches the just-cleared land in preparation for seeding. A seeding apparatus may be affixed to the device to immediately apply native grasses and other forage plants.

Abstract: A mobile frame (10) for supporting an elongate flexible structure (11) such as a ground working tool assembly, the mobile frame (10) is foldable between a first position in which the elongate flexible structure (11) is supported in a working condition in relation to the ground, and a second position in which the elongate flexible structure (11) is supported in a stored condition in relation to the ground. The mobile frame comprises a first frame portion (31) supported for movement over the ground and a second frame portion (32) for supporting one end of the elongate flexible structure. The second frame portion is mounted on the first frame portion for folding movement with respect thereto about a pivot axis inclined to the fore-and-aft axis of the mobile frame such that the spacing between the ends of the elongate flexible structure (11) increases as the elongate flexible structure is moved from the first position to the second position.

Abstract: A chisel cultivator for post-planting cultivation. The cultivator includes a main frame. A chisel member has one end portion coupled to the frame and a second end portion spaced from the first end portion along a longitudinal axis of the chisel member for cultivating sub-surface soil during operation of the cultivator. A heave limiter is coupled to the frame ahead of the chisel member relative to the direction of operation of the chisel cultivator. The chisel member is adjustable relative to the frame to adjust the distance of the second end portion of the chisel member from the frame. A sweep assembly is coupled to the frame behind the chisel member relative to the direction of operation of the chisel cultivator. The sweep assembly includes wings which extend outwardly of a centerline extending in the direction of operation of the chisel cultivator in a plane substantially orthogonal to the longitudinal axis of the chisel member.

Abstract: A rearwardly folding wing-back implement has a V-shaped frame configuration comprising two wing sections having the apex of the V-shape located at a pivot point where the wing sections are joined. A towing linkage minimizes the pulling forces being applied to the wing sections other than those pulling forces applied in the direction of movement of the implement. The implement may be pivoted rearwardly about the pivot point when transport is desired.

Abstract: Commercially available seed planters have V-wings mounted immediately in front of the seed openers to sweep clods away and skim off the top player of the bed. However, V-wings are not effective in trashy and sticky soils. The attachment of the present invention is mounted on the V-wing and has downward-rearward directed fingers extending below the V-wing. The fingers push clods and trash away and assist in maintaining uniform depth in all soils.

Abstract: A reversible mounting bracket for releasably securing a tool to the tool bar of a soil tilling farm implement so that the tool may be readily removed or replaced when desired. The mounting bracket has a base plate adapted to be rigidly attached to the underside of the tool bar by U-bolts. A pair of transversely spaced longitudinally extended upright tool support arms are fixed to the lower surface of the base plate so as to extend in a direction parallel to the direction of travel of the implement. Disposed along the lower portions of each pair of support arms is a tubular socket that is open at the forward and rear end thereof so that the shank portion of the tool may be inserted through either end for securement in the socket by a pin connection.

Abstract: A plow for chiselling the earth at substantial depths, including a framework having a plurality of arcuate chisel blades mounted thereon. A towing tongue is pivotally connected to the forward side of the framework, and a hydraulic piston and cylinder system is connected between the towing tongue and the framework for pivoting the framework between a position of coplanar alignment with the towing tongue, and positions in which the framework is angulated with respect to the plane of the towing tongue. Gauge wheels are pivotally mounted on the framework for selective elevation in relation to the blades, and a hydraulic system is provided for selectively elevating and lowering the gauge wheels by pivotation on the framework. The hydraudlic system for the gauge wheels includes a transversely extending tubular control member mounted on the framework for the plow forwardly of the gauge wheels. Each gauge wheel is connected with the control member by a turnbuckle subassembly.

Abstract: An implement has a frame including beams assembled end to end in the shape of a W with deep tillage members depending from each beam. A towing hitch is connected to the middle of the assembly so that during operation, the beams are inclined with respect to the towing direction and the tillage members can plow deep. An elongated crumbler roller supports the rear of the frame and front ground wheels adjacent the frame sides support the front of the implement.

Abstract: A cultivator for conditioning the earth surface along row crops, the cultivator having a frame adapted for earth traversing movement along rows of such crops; scraper blade assemblies mounted on the frame for floating action; and earth surface engaging, blade depth control skis affixed on the assemblies and forwardly extended therefrom elevationally controlling the scraper blade assemblies in response to the earth traversed thereby.
