    Abstract: A tilling apparatus and a method of tilling soils which includes the use of a rotational shaft having a number of cutter assemblies located at spaced apart locations on the shaft in which each cutter assembly has a multitude of blades which rotate as the rotary shaft rotates to form a plurality of spaced apart trenches having the same spacing as the spacing of the cutters, and a width caused by the width of the blades. As the blades dig the trench, the soil contacted by the blades is granulated and is tossed about by the spinning blades so that some soil falls back into the trench and some falls along the periphery of the trench to form rows of aerated granules which promote enhanced growth of plants or seeds in the trench and along the edge of the trench to improve the yield of pasture having the trenches. Various attachments can be provided on the tilling apparatus, either in front of or towards the rear of the spinning blades for different purposes, such as rippers, seeders, levellers, or similar.

  • Publication number: 20120111588
    Abstract: An exemplary best mode embodiment and various alternative embodiments are shown for combining horizontal and vertical tillage to solve both weed control and penetration of compaction layer. In one exemplary embodiment a large colter or tine is disposed behind a plow, sweep, concave disc, or other horizontal tillage implement to slice the soil to penetrate any compaction created by the implement. In another exemplary embodiment, a colter with lateral blades penetrates a surface compaction layer, chops crop residue and hoes and levels the soil all in one pass with one implement. We have discovered that a deeper-penetrating tailing ground slicing implement behind a horizontal tillage device results in full root depth for a stronger crop and better yields with normally deep-rooted crops such as corn and the like.

    Abstract: This tillage machine disclosure utilizes the original Huxley (1983) patented aerator tine geometry with special features which are different from those patented by Martindale (U.S. Pat. No. 6,854,525). These features are disclosed here in a series of different arrangements within machine frame designs. There are two different embodiments of the enhanced tine design. The frame designs disclosed protect the farmer from maintenance neglect and unintentional misuse or oversight of the tine technology limitations which have led to inconsistent performance in previous framing presentations. These designs result in greatly reduced machine lifetime costs of soil-engaging tines. A wide range of power requirements and concomitant amounts of soil fracturing in relation to the number of tine perforations is achieved to effectively reduce soil erosion potential as a result of the tillage operations.

Edges of the blade can be formed without teeth near two corners and can be sharpened or not. The teeth may extend different distances from the blade. The blade cuts into a surface. In one application, the blade is used for edging or trenching and is rotated generally vertically so as to penetrate the ground and any material on or in the ground such as grass, sod, turf, leaves, thatch and the like.

  • Patent number: 7290619
    Abstract: A soil aeration apparatus may include aeration tines that are actuated by a relatively compact gear system that reduces the size and weight of the apparatus. In addition, a soil aeration apparatus may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts to be positioned closer to one another and reducing the size of the apparatus.

  • Patent number: 7172032
    Abstract: An agricultural implement has gangs of soil aerator tools. Each gang includes a set of integral multi-tine units mounted on a frame for rotation in unison. Each tine unit has a hub with tines. The hub has a first surface defining a first set of indexing receivers and a second surface defining a second set of indexing receivers. At least one indexing spacer separates each tine unit from the next tine unit. Keys of the indexing spacers assemble with selected ones of the first set of indexing receivers or the second set of indexing receivers to establish and maintain a predetermined pattern of rotational index positions among tine units in a group and groups in a gang. A method of rotationally indexing agricultural tools in an assembly. One method includes providing a shaft, tine units, and indexing spacers.

  • Patent number: 6923267
    Abstract: A linear aeration apparatus is operable to form parallel linear aeration trenches into the surface of the ground. Aeration of highly compacted turf areas can be accomplished by first spreading a top dressing material over the surface of the field and then forming linear aeration trenches into the surface of the ground mixing the soil removed from the trenches with the top dressing material. A reciprocating finishing apparatus brushes the mixed soil back into the aeration trenches to stabilize the surface of the ground. A rotary member has radially projecting blades that, upon rotation, form the continuous linear trenches defining unstable islands of earth therebetween. The finishing device includes rearwardly projecting fingers that reciprocate transversely to brush the mixed soil and top dressing material back into the formed aeration trenches to stabilize the islands of earth.

  • Patent number: 6881001
    Abstract: Devices and methods for softening the infill layer of artificial turf. Multiple prongs extend from a rake or a rotating drum or wheel that is pushed or pulled across the artificial turf. In one embodiment, the prongs eject pressurized gas or liquid into the base of the infill. In another embodiment, the prongs vibrate within the base of the infill. Ideally, both methods are employed. The forced gas and/and or fluid, and the vibration, serve to loosen the rubber and sand particulate that make up the infill and thereby soften the artificial field.

  • Patent number: 6854525
    Abstract: A tine assembly comprising a plurality of individual tines, each tine with an arcuate shaped base section and a blade section. Each tine is mountable between a pair of hubs suds that each blade extends radially outward therefrom. The base portions are clamped, secured, or otherwise engaged between the hub assemblies. The blades may be positioned to be twisted in various angles about a line extending substantially radially outwards, by the use of wedge-shaped, arcuate blocks. The blocks and individual tines may be positioned in a multitude of different configurations to providing desired rotational positioning of the tine blade sections.

  • Patent number: 6766865
    Abstract: An improved rotary soil probe is provided with a frame pivotally mounted on the rear of a truck or vehicle for movement about a horizontal axis between raised and lowered positions. A rotatable wheel is pivotally mounted to the frame for movement about an upwardly angled axis between an extended use position and a folded transport position. The wheel includes probes extending radially outwardly from the perimeter of the wheel. The probes are adapted to receive soil samples as the wheel is rolled along the ground. Plunger assemblies automatically discharge the soil samples on each rotation of the wheel so that the samples can be continuously collected, without the need to stop to clean out the soil samples.

  • Patent number: 6739403
    Abstract: A tine assembly for a cultivator includes a first tine member having a plurality of radially extending non-planar tines. At least two tines on each tine member differ in shape from the remaining tines. The tine assembly may include a second tine member which is shaped like a mirror-image of the first tine member. When assembled on a shaft, the second tine member is off-set from the first tine member so that tines on alternating tine members contact the ground as the shaft rotates.
