Abstract: A method of harvesting sod using a sod harvester involves the formation of a series of discrete slabs of sod that are positioned end-to-end, and conveyed up a conveyor that is driven at ground speed so that the slabs stay together. Netting is introduced continuously below the series of slabs as they enter a roll-forming enclosure of the harvester. The netting keeps the slabs together and allows them to be formed into a roll in essentially the same fashion as a continuous strip of sod. Roll formation is continued until a large diameter roll has been formed comprising multiple layers of sod slabs. The large roll forms a unitary structure wrapped in netting that can be manipulated and transported to a laying site in the same manner as a large single strip roll. At the site, the roll can be tipped onto its side, exposing the netting for removal and permitting individual slabs of sod to be pulled away from the roll and carried off for laying.

Abstract: A sod harvester includes a cutter for forming a strip of cut sod, and an inclined conveyor for conveying the strip from the cutter to a roll-forming enclosure. The roll-forming enclosure comprises two belt conveyors at right angles to one another. The strip is delivered onto a generally horizontal one of the two conveyors, by which it is moved towards the second conveyor. The second conveyor then causes the leading end portion of the strip to turn back on itself and form the roll. A pair of spring-biassed fingers ensure proper roll formation. The strip of sod is cut transversely at an appropriate point and the sod within the enclosure is rolled up to complete the roll. The enclosure is turnable about a vertical axis to a laterally directed position, in which the roll can be discharged laterally clear of the next pass of the harvester. The roll can be wrapped in netting which is automatically cut as the roll-forming enclosure turns.

Abstract: The plow apparatus has plow blades to break up the soil in the plowed field. The broken up soil is scooped up with scooper blades by the forward motion of the plow apparatus and then conveyed to rotating tillers. The tillers break up the soil into smaller clumps.

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 preferably by a hydraulic motor to rotate about upwardly and forwardly extending axes at variable speeds so that the angle through which each slice is turned can be adjusted depending on the soil condition. Projections within the drums turn the furrow slices which can be inverted and deposited to the rear. Also, an upper guide roller or auger can be located above the drums to guide and/or laterally displace the slices as they enter the drums.

Abstract: The method and apparatus for continuous turn-over of soil in accordance with the invention are characterized in that the turn-over of soil takes place in a system including a rotor, the direction of rotation of which is opposite to the wheels of a vehicle drawing the rotor, and symmetrically-shaped plough units cooperating with the rotor in such a way that the pikes of the bows of the rotating rotor engage the soil, which has been lifted by the plough unit, from beneath and from behind, as seen in the direction of movement of the apparatus. The flow of soil thus lifted up is divided up into transverse pieces, which are turned and deposited behind the apparatus. During this process the rotary movement of the rotor is independent of the control of the displacement movement of the apparatus. Also, the compactness of the soil material may be levelled out to the required degree through preparatory working. Reference FIG. 1.

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.

The method of moving earth comprises advancing an earth moving blade through a continuous ridge of earth in a manner such that the speed of advance of the advancing earth moving blade is synchronized with the speed of movement of a laterally travelling earth moving track so that substantially all of the earth is moved laterally in the direction of travel of the laterally travelling earth moving track.

Abstract: A plow has spaced apart furrow cutters and a furrow elevating structure that loosens and raises a continuous wide furrow strip to a furrow turning device during plow travel. The turning device can be an open ended drum that is rotated or stationary. Within the drum, a worm conveyor is rotated that first engages and depresses the furrow top, but as the furrow strip passes through the drum, it is inverted and to some extent, winds around the conveyor so that the furrow strip has a cross section that resembles an inverted shallow U. The inverted and deformed strip is deposited in the furrow being formed. The conveyor is normally located about centrally of the drum interior so that the furrow strip top is first engaged by the conveyor's lower surfaces, but as the strip is urged through the drum, it is inverted and supported on top of the conveyor before being deposited to the rear. The method of cutting, inverting and depositing the deformed continuous furrow strip is claimed.
