Abstract: A multi-piece cutting edge attachment for a circular shaft of a harrow tine features a mounting member formed of a material that is weldable to, and distinct from, a first material of the harrow tine. A cutting edge member is formed of a third material that is harder than the first and second materials and less weldable to harrow tine than the second material of the mounting member. The cutting edge member has a front face and an opposing rear face that is conformingly shaped for placement against a front face of the mounting member at a lower end thereof. The multi-piece arrangement forms a cutting edge of greater hardness than that which is achievable by a material directly attachable to the tine itself.

First and second parallel connecting arms are pivotally secured to the bracket arms whereby the attitude of the tines with respect to a vertical plane can be adjusted by longitudinally moving one of the connecting arms with respect to the other. A stop means interconnects the connecting arms to prevent longitudinal movement of one connecting arm with respect to the other in first longitudinal direction, but permits free longitudinal movement between the connecting arms in an opposite longitudinal direction.

Abstract: The invention disclosed relates to a mechanism for adjusting the level, tine working depth, and tine working angle of a framework supporting a multiplicity of cultivator tines. The framework is cantilevered from and behind a boom drawn on wheels, and includes a pair of rock shafts that are:1) rotated together to adjust the working depth of the tines,2) rotated relative to one another to adjust the level of the working depth of the tines; the working angle of the tine is adjusted by mechanical rotation of frame tubes forming part of the framework and on which the tines are directly mounted.The invention disclosed also includes a novel hydraulic circuit for powered rotation of the transverse frame tubes and of the boom between a working position when the tines are engaged with the ground and a transport position when the tines are clear of the ground and the framework carried in a position facilitating transport.

Abstract: The invention is designed primarily for use with resilient tine components which include a pair of resilient spring coils having an attaching U extending between adjacent ends and a resilient tine extending from the outer end of each of the resilient coils substantially perpendicular to the longitudinal axis thereof. These often wear and the most expensive replacement cost is the resilient spring coils. The present invention overcomes these disadvantages by provided a sleeve which engages over the worn ends of the tines and is secured thereto and which has a replacement tine portion secured within the other end of the tubes and extending axially therefrom thus returning the tines to their original length. The sleeves can be secured to the worn ends of the tines either by welding, set screws or other means.

Abstract: A folding cultivator is disclosed wherein first and second sets of downwardly extending teeth are attached to the rearwardly folding wing of the cultivator at spaced intervals along its length. The teeth are arranged so that teeth of one set are located on each side of a tooth of the other set. In addition, the distal ends of the teeth of one set are located forwardly with respect to distal ends of the teeth of the other set. When the wing frame of the cultivator is folded and unfolded to achieve transporting and operating configurations, respectively, the teeth of a central wing section and those of outer wing sections intermesh without entangling and damaging each other.

Abstract: A soil-cultivating implement has soil-working members mounted for rotation about corresponding upwardly extending axes. A soil-working tool, preferably one or more tines, is connected to a support of the soil-working member by at least one quick release fastener. The tool or tine can be a torsioned spring steel strip or a rod that has a spring coil. Each tine can have one or more operative soil-contacting ends that are spaced apart from one another. When the operative ends are located one above the other, the soil-working member can work deep in the soil. The fastener can be a pin that extends horizontal and at right angles to the axis of rotation of the soil-working member so that the operative ends can pivot to some extend about the fastener. The ends of each tool or tine can extend in different directions from one another and tines in pairs can be mounted on the same support.

Abstract: A clamp for mounting an agricultural spring tooth to a square cross section tool bar includes an L-shaped angle bracket, one leg having a transverse slot near a free end thereof, the other leg having a bolt receiving aperture near its end, and a partially channel shaped retaining clip having a transverse slot near one end and a bolt receiving aperture near the other end. The bracket is mounted on the tool bar in contact with two adjacent sides of the square bar, the mounting of the spring tooth shank being received in the bracket slot and contacting another side of the bar, and the clip being overlayed on the mounting shank with the end of the one leg received in the clip slot. A bolt is passed through the other leg, the clip, and the shank, clamping same together on the tool bar. Side flanges on the retaining clip rest adjacent side edges of the mounting shank whereby, in cooperation with the clip slot, lateral pivoting of the tooth is resisted.

Abstract: A cultivator or harrow has a row of soil working members and each of these members is a rotatable support on a shaft that is driven to rotate about an upwardly extending axis. Each support is comprised by two similar diametrically opposed portions and each portion has a lower tine and an upper tool that differs in shape and form from the lower tine. The upper tool can be a pair of different tines or a tine-like extension of the support portion that functions as a rigid tine. The lower more resilient tine works the sub-soil and the upper tool works the topsoil. The lower tines of the two portions can be a single element of spring steel that is retained by quick release pins in lower support recesses and the fastening portions of the lower tines can bear on the heads of further pins that retain upper tines in their corresponding recesses so that one release means retains all of the tools on each support portion.

Abstract: A dethatching unit is mounted for attachment to the front end of a self-propelled lawn mower, for example, so that the dethatching unit is pushed by the lawn mower and thatches the ground prior to mowing thereof. The dethatching unit includes a frame having a caster wheel at its forward end and arms at its rear end for attaching to the mower. The wheel and the arms cooperate so that tines, which are mounted in two rows on the frame, do not carry any of the weight of the unit so that the bottom tip of each of the tines is slightly spaced from the ground in its rest position. Each of the tines in each of the rows is offset from each of the tines in the other row. Forward motion of the dethatching unit causes the bottom tip of each of the tines to deflect rearwardly and downwardly as it comes in contact with grass. In their deflected positions, the bottom tips of the tines contact the thatch layer to tear it loose from the soil and ultimately flip the thatched material to fall on the ground.
