Abstract: An agricultural tillage implement that employs multiple apparatus to carry out a strip-till farming operation is disclosed. A tillage shank runs a point through the compaction layer to fracture and loosen the soil, forcing it upwardly and outwardly where a pair of angled soil-gathering blades, located adjacent the shank, redirect the soil into a newly created berm. A trailing conditioning rotary reel having a particular cross-sectional profile forms the soil into a uniform raised berm ideally suited for planting.
Abstract: A cultivator comprises an array of laterally-spaced soil-inversion discs having their centers arranged in a substantially horizontal line lying at not more than 30.degree. to a transverse plane of the cultivator and being mounted for rotation about individual axes which are equally inclined to the vertical and, when viewed in plan, also to the longitudinal plane of the cultivator.

Abstract: A plow has coupling members at its forward side for connection to a multi-point hitch of a tractor. Furrow slicing members at the front form furrow slices which are elevated to furrow turning drums during operation. The furrow slices are turned about their longitudinal axes and deposited to the rear by the rotating drums. The drums are mounted on rollers and driven to rotate about upwardly and forwardly extending axes at preselected speeds. Projections within the drums turn the furrow slices which can be inverted and deposited to the rear.
Abstract: A cultivating implement include a soil working tool having an elongate substantially planar blade. The blade extends sidewardly and downwardly at an acute angle to the vertical so that its plane is substantially parallel to the direction of movement through the soil and so that soil is lifted without inversion over the blade during passage through the soil. A movable extension is mounted to the blade trailing edge and is adjustable between first and second rigid positions to adjust the lifting action on the soil and thus adapt it to a wide variety of soil types and moisture conditions. At the lower end of the blade is a shoe member with an upwardly and rearwardly inclined upper surface at a leading end thereof, and an upright and rearwardly extending side surface substantially parallel to the direction of travel to provide a bearing surface for resisting lateral forces on the tool due to lifting action of the blade. The shoe member imparts lateral stability and factilitates penetration.
Abstract: A plow is structured to wholly or partly invert a furrow slice during operation. The furrow slice is cut loose by a leading V-shaped blade and is both compressed, and deflected laterally towards a side wall of the frame by a plurality of rotary lateral displacing rollers arranged in a row inclined to the direction of travel. The rollers are preferably of progressively increasing size towards the rear and co-operate with a soil guide surface at the rear of the plow in turning the furrow slice about an axis which extends in the direction of travel to deposit the slice substantially completely back into the furrow from which it was originally cut. In one version, the row of displacing rollers leads to a power-driven rotary soil guide unit of annular formation, the inverted furrow slice being delivered back into the furrow from which it was cut through the interior of the unit.
