  • Publication number: 20120145420
    Abstract: The present disclosure relates to soil treating systems and shearing assemblies for use in forestry operations. Embodiments of soil treating systems according to the disclosure include a movement assembly having a front end and a back end, a shearing assembly mounted on the front end of the movement assembly, and leveling assembly mounted on the back end of the movement assembly. In some embodiments shearing assemblies are inverted V-type shearing assemblies. Further aspects of the disclosure are directed towards methods for using soil treating systems and shearing assemblies for preparing land for interplanting an energy crop with a primary crop.

  • Publication number: 20080257574
    Abstract: The GOAL PLOW TECHNOLOGY (GPT) is an agricultural method, with great impact on the physical and biological behavior of the ground. GPT makes horizontal cuts in the soil, without inverting the soil's layers. GPT achieves this by following the terrain's contours as originally formed by Nature. GPT's angles and devices successfully move the soil in the opposite direction of the earth's gravity. GPT is adaptable to any kind of soil, for cultivation or tillage, and can easily be used by itself, or used in combination with other farming systems. The presently existing agricultural implements destroy the natural structure of the soil. As their use diminishes, GPT will yield maximum benefits. In addition, GPT is the ideal technology for organic food production, as it favors the accumulation of biomass at the ground's level.

  • Patent number: 5409068
    Abstract: An agricultural plow implement includes a number of upright supports, with each support supporting a shallow tillage V-shaped sweep blade. A mounting plate is attached to the rear of each upright support and a specially adapted ripper shank, with an attached deep penetrating ripper blade, is attachable to each plate via a pair of bolts which extend through respective mounting bores in the plate. One of the bolts in each pair is a pivot bolt which provides a pivot point about which the ripper shank can swing. The other bolt is a shear pin which is designed to shear off should the ripper blade encounter an obstruction which might otherwise bend or break the ripper blade and/or the ripper shank. The ripper shank is adjustable vertically relative to the sweep blade and the ripper shank can also be pivoted 180 degrees between operative and non-operative positions when it is desired to do a sweep operation without soil ripping.

  • Patent number: 4909335
    Abstract: An agricultural earth working system including a vertically adjustable deep tillage tool in tandem with a V-shaped sweep blade tool, the system being mounted on a field traversable frame and adapted to be drawn through the field by a conventional farming tractor. A disk is positioned in front of a shank for the sweep blade tool. The system cuts roots of weeds with the sweep blade and at the same time deep shatters or cultivates the soil with the deep tillage tool in such a manner that very little of the field surface is disturbed, so as to retain stubble cover and prevent erosion, yet destroying the weeds and sufficiently working the ground beneath the surface, especially with the deep tillage tool to enhance water absorption.

  • Patent number: 4856597
    Abstract: A soil preparation machine is pulled by a tractor across a field in which rows of plants and tracks followed by the tractor are at permanent locations from season to season. Soil from between the remains of two rows of the previous season's plants is lifted by a blade and delivered to the forward end of a belt conveyor which is slanted rearwardly and upwardly. Devices on the machine upturn the remains of the previous season's plants and the soil beneath them. Soil falls from the rear end of the conveyor onto the upturned remains. The blade and conveyor are narrower than the distance between the rows of plants, and the upturning devices are aligned with the rows of plants inboard of the tractor tracks.

  • Patent number: 4817727
    Abstract: Combination sweep and subtiller having a plurality of leg shanks extending downward from the sweep. Each shank is angled in the direction of travel to push soil toward the center of the sweep, and simultaneously to provide minimal draft. In addition there is a horizontal bend midway between the upper and lower extremities of the shank so that the lower extremity is bent toward the center of the sweep in order to cause a soil fracture plane in the direction of the center of the sweep. The lower end of the shank has a diagonal bend toward the center of the sweep to agitate the soil thereby.

  • Patent number: 4726428
    Abstract: A minimum upper ground layer and stubble disturbance tillage unit is provided including a pair of dependingly support opposite side plates between whose lower end a horizontally elongated blade assembly is supported with the blade assembly including front and rear marginal portions and disposed in an inclined position with the front marginal portion lowermost and the rear marginal portion uppermost. The blade assembly includes longitudinally spaced V-shaped cutting edges disposed along the forward marginal edge thereof and disposed in a forwardly and downwardly inclined plane generally paralleling the blade assembly. The V-shaped cutting edges are positioned with their apex portions forwardmost and define included angles of graeter than Rotary members are disposed rearward of the blade assembly and include upper portions spaced above the upper rear marginal edge of the blade assembly. The rotary members are radially aligned with the junctures between pair of adjacent V-shaped blades.

  • Patent number: 4015666
    Abstract: An undercutting knife for a sod cutting machine. The knife has an undercutting blade having a front portion and an upwardly bent rear portion. Connected to the rear portion are two support and guide members, one at each edge of the blade. Each support and guide member extends rearwardly from the blade and has a rear portion projecting laterally of the blade. Mounting arms are connected to the laterally extending portions. The mounting arms, which are connected to mechanism for supporting and reciprocating the knife, are clear of the ground and are spaced laterally of cut sod moving over the knife, so as not to tear the edges of the sod. A guide strip extends rearwardly from the blade between the support and guide members. The support and guide members and the guide strip can be three discrete members or a single integral unit.
