  • Patent number: 8020629
    Abstract: A low till agricultural implement has a frame with a hitch for attachment to a tractor. An shallow-angled blade gang composed of an array of parallel ultra-shallow inclined disk blades is mounted to the front of the frame, and is followed by at least one wheel, spiral reel, and spike tooth harrow. The ultra-shallow inclined disk blades are mounted perpendicular to rotating shafts, and slice through field residue and soil with minimal lateral movement of material. The blades of the following reel then make cuts nearly perpendicular to those made by the circular blades. A trailing rolling basket or other finishing implement follows the spiral reel. The implement aids in drying the soil surface layer. Also, by cutting up residue and evenly spreading debris and topsoil, the implement helps to warm up the soil.

  • Patent number: 4163329
    Abstract: The disclosed apparatus is a machine of the type for connection to a snow skiing course maintenance tractor. It has freely-rolling rollers for compacting the snow and a plurality of scrapers arranged side by side. The scrapers are pivoted vertically about an axis which is adjustable in height. The scrapers are arranged in front of the rollers.Also disclosed is such a machine with combinations of scrapers and rollers arranged on side by side sub-frames which are connected together by a linkage. When one of the sub-frames is tilted in one direction, the other sub-frame is caused by the linkage to tip in the opposite direction. Means are disclosed for utilizing only one of the sub-frames alone.

  • Patent number: 4131163
    Abstract: A stubble eradicating implement adapted for earth traversing movement along a ridge having stubble and other debris thereon and having furrows on opposite sides of the ridge, the implement having a frame, guide wheels mounted on the frame; a pair of concavo-convex disk blades mounted on the frame in fore and aft spaced relation rearwardly of the guide wheels for free rotation about individual axes lying in vertical planes oppositely forwardly convergent with the ridge and oppositely forwardly inclined in their respective planes so that the concave faces of the disks are forwardly and upwardly disposed with the disk blades overlapping in earth engagement centrally of the ridge to discharge stubble and debris from the ridge into adjacent furrows, a first furrowing shovel mounted on the frame rearwardly of the disk blades in alignment with the ridge to discharge soil onto stubble and debris in the furrows, a compacting roller mounted on the frame rearwardly of each of the first shovels in alignment with their re

  • Patent number: 4126186
    Abstract: A cultivating implement has rows of rotatable soil working cultivating members that are mounted on beams extending transverse to the direction of travel, one behind the other. The members rotate about upwardly extending axes and can be positioned along the beams to cooperate with one another and work soil between rows of plants. Assemblies of crumbler-rollers are secured to the frame and positioned to engage soil worked by the cultivating members but avoid the plant rows. Each assembly is secured by a support arm adjustably settable along the length of a beam at the rear of the frame. Each assembly is a pair or two rollers journalled on a common shaft and each roller has two supports, one of which is movable along the shaft to and from the other to adjust the width of the roller. Each support mounts bars that form the periphery of the roller.

  • Patent number: 4086965
    Abstract: A cultivator implement has two rows of freely rotatable, tined soil-working members connected to leading and rear transverse frame beams by respective brackets or plates. Each rotatable member is mounted for rotation on a corresponding stub shaft that defines its axis of rotation, which is inclined to the vertical. Pairs of downwardly extending tines that are secured in respective holders around the axis of rotation, contact the ground and rotate each member. A first row of rotatable members have axes inclined to one side of the vertical and a second row of rotatable members have axes inclined to the opposite side of the vertical. A fixed cultivator tine is deflectably secured to the beams via an integral spring coil assembly. The cultivator tines are positioned non centrally between adjacent rotary members and each tine is curved so that its lower tip extends forwardly.
