Abstract: A gardening system includes a drive shaft operably coupled to first and second shafts for driving the first shaft in a first direction and the second shaft in a second direction. A first ground manipulation device is attached to the first shaft. A second ground manipulation device is attached to the second shaft.

Abstract: A cover crop termination system includes a smooth drum and a crimping arm assembly operatively connected to the drum through a cam mechanism including a cam follower. The crimping arm assembly includes a plurality of crimping assemblies having crimping bars which crimp the cover crop after it has been rolled in order to prevent resprouting of the crop.

Abstract: The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a disc/drive unit. The disc/drive unit includes first and second pluralities of discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned in front of the first discs is a ground-engaging driver rotatably coupled to the frame for rotating as the driver engages and is moved across the ground along the direction of travel. A driven flow controller is rotatably coupled and situated between the plurality of first discs and the plurality of second discs. The ground-engaging driver is operatively controlling and preferably accelerating the rotational speed of the driven flow controller.

Abstract: A crumbler roller device 10 comprises two co-axial soil-engaging rotors 12, 13 mounted one within the other and drive means operative to drive the inner rotor 12 at a different rotational speed to the outer rotor 13.

Abstract: A rod weeder attachment for the tool bar of an agricultural implement comprises an arm portion extending rearwardly from a clamp on the tool bar defined by a pair of spaced parallel bars extending rearwardly to a transverse strut. From the strut to the ground is provided a rear arm portion the angle of which can be adjusted relative to the front arm portion. The rear arm portion carries on the lower end a ground wheel for running on the ground and providing drive therefrom. A pair of shanks at opposed ends of the strut extend down to the ground and carry at their lower ends a rod which is driven by a chain mechanism from the ground wheel. Springs allow the arm to lift relative to the tool bar.

Abstract: To prevent the development of clods on the soil surface when using a soil layer cultivator for the deep loosening of a field or the like, a pressure roller is provided to travel over the soil surface rearwardly of the elements effecting the deep loosening of the soil. The pressure roller is made up of several sections mounted on a common shaft with the individual roller sections located between support posts on a frame tube which posts support the loosening elements. The roller sections may be hinged individually or in groups to the frame tube. The rollers may roll freely over the soil surface or a forced drive for the roller sections can be provided.

Abstract: Apparatus for making ski trails which is towed and comprises a drag having a cutter unit and a snow crushing unit mounted behind the cutter unit on the drag. The units have radial blades and rotate about an axis transverse to the direction of travel of the apparatus. The cutter unit derives its rotary motion from the tamped track of the snow and is connected by a transmission to the crushing unit whereby the latter derives its rotary motion from the cutter unit.

Abstract: The apparatuses comprise a horizontally extending rigid frame and a plurality of reel and shaft assemblies, those reel and shaft assemblies each comprising a pair of parallel axle shafts and a set of reels rotatably supported on each of said shafts; the peripheral edges of ground engaging blades on a first set of rotatable reels meet the ground in the treated path at a first angle to or parallel to the central longitudinal axis of a first shaft on the frame and the peripheral edges of the ground engaging blades on a second set of rotatable reels meet the ground to form cuts therein at an angle to the line of the edge of the blades of the first set of reels.

Abstract: A lawn cultivating machine comprising two parallel cutter shafts which are onnected together by a transmission gear and are rotatable about their axes, and on each of which shafts a plurality of cutters are arranged at spaced intervals from each other, the cutters of one shaft being displaced relative to the cutters of the other shaft, in which the speeds of the cutter shafts are in a certain transmission ratio and the directions of rotation of both cutter shafts are identical.

Abstract: A power tillage device is provided having a passive rolling coulter as the prime mover for a power tillage blade which is carried in the lead of the coulter on a transfer case mounted as a radius arm on the counter shaft. The tillage blade rotates in the opposite direction from the coulter and is designed for optimum efficiency for shearing and lifting soil from a furrow.

Abstract: An elongated downwardly opening housing is provided for lengthwise advancement over the ground and includes mounting structure for dependingly supporting the housing from a farm implement tool bar. The housing includes front and rear transverse journaled horizontal shafts each having a pair of axially spaced circumferentially spiked wheels mounted thereon for rotation therewith. Corresponding ends of the shafts project outwardly through opposite sides of the housing and have aligned sprocket wheels mounted thereon. The sprocket wheel carried by the forward shaft is at least slightly greater in diameter than the sprocket wheel carried by the rear shaft and an endless chain is trained over the sprocket wheels drivingly connecting the forward shaft or front shaft to the rear shaft.

Abstract: A soil cultivator has a beamed frame with a coupling member to be attached to a tractor. A plurality of rotatable tined soil working members are mounted in a row that extends transverse to the direction of travel. The soil working members are power driven by driving means to rotate about upwardly extending axes and work overlapping strips of ground. The action of the tines breaks up soil, even heavy soil, and a roller is connected to trail the soil working members. The roller has annular plates the outer peripheries of which are formed by horizontally extending elongated elements that engage and smooth the ground behind the tines. The roller is adjustably pivoted to the frame by arms to support the weight of the cultivator. By moving the arms about pivots, the working depths of the tines and the amount of weight borne by the roller can each be regulated to a significant extent.

Abstract: A rod weeder attachment for the tool bar of an agricultural implement comprises an arm portion extending rearwardly from a clamp on the tool bar defined by a pair of spaced parallel bars extending rearwardly to a transvese strut. From the strut to the ground is provided a rear arm portion the angle of which can be adjusted relative to the front arm portion. The rear arm portion carries on the lower end a ground wheel for running on the ground and providing drive therefrom. A pair of shanks at opposed ends of the strut extend down to the ground and carry at their lower ends a rod which is driven by a chain mechanism from the ground wheel. Springs allow the arm to lift relative to the tool bar.
