A tamper resistant safety gun lock (20) utilizes a case (22) having opposing sidewalls (24, 26) and at least one lateral wall (42, 48, 62) to inhibit access to crucial components of a firearm (28). A plurality of gun anchor posts (34) are selectively positionable inside of the case (22), so that the case (22) may be adapted for different types of firearms (28). The gun anchor posts (34) are held in a perforated plate (74) and have a flat disk (68) at one end which is held between the perforated (74) plate and one of the sidewalls. Because the flat disk (68) is held between the perforated plate (74) and one of the sidewalls the gun anchors (34) are generally inaccessible from the exterior of the case. The tamper resistant safety gun lock (20) is provided with a lock mechanism (32) which utilizes a catch (100) extending inwardly from a lateral lock wall. (48). The catch (100) is covered to make the case (22) difficult to pry open. Further, the lock mechanism utilizes a latch plate (92) having a width perpendicular to an opening direction (106) of the case (22) to provide additional strength against the case (22) being pried open.

The zone tiller attachment employs a pair of spoked tillage wheels that converge downwardly and forwardly toward one another in leading relationship to the planter and in such an orientation that their heavy, thick, blunt spokes mutually intersect and overlap one another along the lower front extremity and bottom portion of the tiller. The crossed spokes penetrate into the soil to pulverize, cultivate, and substantially disturb the soil particles in place with a churning action while also displacing surface residue to opposite sides of the path of travel, thus producing a relatively narrow band of thoroughly tilled soil having a depth extending down to or below the seed planting level such that the trailing opener can perform its trench opening and seed placement functions in the optimum manner. The individual spokes of each wheel are preferably constructed from short sections of sturdy metal cable formed by individual strands of thick wire twisted into a common, unitary body so that strength with a certain minimal amount of flexibility is achieved to prevent breakage and facilitate the self-discharge of foreign objects. The spokes are disposed at non-radial, raked backed angles so as to strip cleanly out of the soil on the rear, upsweep side of the wheels and leave the soil in place, instead of throwing it to the side.

The subsoiler has shank assemblies which are designed to cut a thin, clean slice in the soil without frontal upheaval forces that would cause eruption of the soil in a turbulent manner ahead of the shank line. The soil lifting components at the bottom of the shank are configured to produce generally laminar soil flow over and around their lifting surfaces so that the upwardly and outwardly directed fracturing forces occur behind the leading shank line in a readily controllable manner and without disturbing residue and other materials on top of the ground. The subsoiling profile at the bottom of the shank may be varied by interchanging variously configured points and caps which are securely but removably secured to the shank. An alternate embodiment provides adjustment of the profile presented to the soil by having a portion of the component angularly vertically adjustable to vary the angle of attack of its lifting surfaces.

The placement device utilizes a flat, upright shank having a pair of rotatable residue cutting discs secured to opposite faces of the shank just outside of a slender, generally crescent shaped, replaceable insert component at the bottom of the shank which is only slightly wider than the shank itself. Instead of transverse fasteners which would widen the overall width of the assembly, a single draw bolt extends generally longitudinally of the shank and attaches the lower component to the lower end of the shank which is configured in the nature of a notch so as to complementally receive in edge-to-edge abutting relationship a matingly configured corner of the component.

Replaceable tillage point

The ridge preparation tool is adapted to be attached to a seed planter directly ahead of the trench-forming structure of the planter so as to skim off the crest of the ridge for the production of a clean, relatively narrow strip of prepared soil in which the trench-forming structure can operate effectively. The free-wheeling skimming disc of the tool is held at an oblique angle to the centerline of the planter and may be adjusted to increase or decrease the extent of side throw of the skimmed off materials by selectively raising or lowering an outwardly bent mounting arm that holds disc at its oblique angle. Raising or lowering the angled mounting arm causes the disc to cock inwardly or outwardly while maintaining the same oblique angle. The throw-adjusted disc can be returned to the same skimming depth by appropriate manipulation of a vertical adjustment unit associated with the tool.

Replaceable deep tillage point

The point is adapted to fit onto the forwardly projecting mounting wedge of a tillage shank and has a downwardly and forwardly inclined, elongated crown provided with a transverse, sharpened tip at its lower front end. An underslung transverse wall looped under the crown at the front end of the point defines a rearwardly opening socket that matingly receives the apex of the mounting wedge of the shank, and depending sidewalls on the crown adjacent its opposite lateral edges rearwardly of the underslung wall serve to present a protective trough on the underside of the crown that matingly receives the upper surface of the mounting wedge so as to protectively cover otherwise exposed side portions of the wedge and thus shield such areas from exposure of abrasive soils. Two alternate embodiments are disclosed, one of which has lateral side edges of the crown intersecting cleanly with upright surface of the underslung wall and the sidewalls, and the other of which has side edge of the crown overhanging such structures and provided with a certain vertical thickness dimension.

Deep ripper point

The applicator comprises a relatively thin, streamlined knife blade adapted to be positioned with its longitudinal axis inclined upwardly and rearwardly during use with a leading edge of the applicator slicing through the subsoil and a lowermost and forwardmost point thereof penetrating the subsoil for the progressive entry of a wedge immediately behind the point which firms up and smooths the lowermost portion of the slice being created by the knife. Upwardly and rearwardly inclined, streamlined wings at the bottom of the blade but above the wedge project beyond the rear of the wedge to define a pocket into which anhydrous ammonia or other substances can be deposited. In one embodiment, the wings commence at the point and diverge rearwardly therefrom at a faster rate than the wedge to provide increased surface area for lifting and fracturing the soil as the knife moves therethrough, providing particular relief in root-bound subsoils. In a second embodiment especially suited for soils which are not self-closing, a pair of outwardly projecting closing fins are provided above and generally rearwardly of the wings to cause the rearwardly flowing soil to be directed downwardly and rearwardly into the slit and around and behind the knife, thus promoting closing of the slit and retention of the deposited substance.
