  • Patent number: 10375873
    Abstract: A landscaping tow apparatus for cultivating dirt or land. The apparatus includes a U-shaped bracket rotatably secured to a tool head support, wherein the tool head support includes a plurality of tool heads removably secured thereon for cultivating the land. A hitch is further affixed to the U-shaped bracket and can mount the apparatus to a vehicle, such as a tractor or riding lawnmower. A pair of wheels are extendable from the bracket in order to engage the ground and lift the tool head support for rotation thereof. In operation, the hitch is secured to a tractor and the side of the tool head support having the desired tool head is positioned against the ground. The wheels are extended so that the tool head support can be rotated in order to have a different tool head engage the ground.

  • Patent number: 9315969
    Abstract: A work vehicle includes a vehicle main body, a work implement, an engine, an idle reduction execution portion, and a position determination portion. The work implement is provided in the vehicle main body and includes a boom provided to be drivable in a vertical direction, an arm provided to be drivable with respect to the boom, and a bucket attached to a tip end of the arm. The idle reduction execution portion can stop the engine in an idling state. The position determination portion determines whether or not the bucket may interfere with the vehicle main body, based on a position state of rest of the work implement. When the position determination portion determines that the bucket may interfere with the vehicle main body, the idle reduction execution portion does not stop the engine, and when it is determined otherwise, the idle reduction execution portion stops the engine.

  • Publication number: 20090290940
    Abstract: A soil structure tool for building structures in soil, placing structures in soil, or both, may improve the load bearing capability for soil by using multiple devices as part of a single tool. The soil structure tool may be operated to place a first device in a working position while placing the remaining device or devices in a non-working position so the first device in the working position may be used without interference from the remaining tools. Moving devices attached to the soil structure tool between the working and non-working positions permits building structures in soil or placing structures in soil without requiring multiple vehicles or other platforms to hold various devices and without requiring multiple devices to be attached to or detached from a vehicle or other platform.

  • Patent number: 6247539
    Abstract: Implements for attaching to a hand-held, powered “Weed-Eater” type device to perform various work or chores (filament cutting, blade cutting, brushing, blowing, mixing, etc.). After disconnecting the device's original implement typically a spool of filament (6) with a bumper feed (7), an initial, cultivator/cutter implement (10), cylindrical in shape with a substantially solid, circular top (12) and a relatively thin, continuous wall of constant thickness, is attached by an appropriate threaded member (e.g. a nut or bolt, usually with one or more washers) to the bottom end of the powered device (FIGS. 1A-D) through a central opening (13). The cultivator's top includes a series of circumferentially spaced, “snap-in” openings (14; e.g. two or more) through and into which other implements (e.g. those of FIGS. 3-20) can be attached (FIGS.

  • Patent number: 5287935
    Abstract: A manual tool for cutting and removing weeds and grass (11) from gardens and landscaping beds, having a cutting blade (9) and rake (1) attached to the rear and front respectively of a chassis (5) mounted on an axle (4) and wheels (3a, 3b) with a handle (6) angularly attached to the rear of the chassis (5). The cutting blade (9) is preferably concave shaped with a front concave cutting edge (13). When the tool is pushed forward by the handle (6) the concave cutting blade (9) pulls and cuts weeds and grass (11) below the surface of the ground (7). The cut weeds are then removed by pulling backward on the handle (6) which drags tines (2) on the rake (1) over the ground (7) to gather and remove the weeds (11). Optionally, the rake (1) is removeably attachable so that the tool can be used only for cutting weeds (11) as desired.

  • Patent number: 5094299
    Abstract: Equipment for attachment to a vehicle having a three-point hitch. The disclosure discloses a novel implement, and an interface adapted to be interposed between the implement and the hitch. The implement preferably has at least two different sets of working elements. The implement and the interface are preferably adapted to accommodate 180 degree rotation of the implement with respect to an axis extending between the implement and the interface, whereby either set of working elements can be disposed adjacent the ground or other surface to be worked. Rotation of the implement with respect to the axis is prevented while the implement is being used to work the ground.

  • Patent number: 4478289
    Abstract: An improved subsoil ripping device is disclosed in which ripper teeth are mounted on the sides of a tracked, crawler-type prime mover approximately opposite the center of mass. The frames carrying the ripper mechanisms are most conveniently mounted on the arms of a conventional bulldozer blade. In order to increase resistance to lateral forces acting on the ripper teeth, the frames may be bridged by a rigid arch. Alternatively, they may be braced by a strut acting between the ripper assembly and the tractor frame. If this latter arrangement is used, the ripper assemblies are preferably hinged to the blade arms to permit full normal blade movement. A ripper made according to the present teaching is especially useful when operating on uneven or debris covered ground. It does not tend to rake up debris, and thus does not require time and fuel for clearing the teeth. Because of the location of the teeth, the prime mover is easier to steer and a rip of more uniform depth can be maintained.

  • Patent number: 4448260
    Abstract: A universal earth-loosening attachment useful with earth-moving vehicles. The attachment mounts to the back side of tractor and bulldozer blades. The attachment includes a spike which engages the earth for loosening the earth during backward motion of the vehicle and which automatically swings upwardly to drag inoperatively on the earth surface during forward motion of the vehicle. Adjustment means allow the spike to engage the earth at an optimum angle relative to the earth grade for efficient operation. The spike is self-storing in an upright position.

  • Patent number: 4173261
    Abstract: An assembly for creating furrows in a freshly plowed field. The furrows, two to three feet apart, are usually created in the fall and are useful for retaining moisture in the soil during the winter months and are helpful in preventing soil erosion by the wind. The furrowing assembly is detachably mounted on a mulcher bar assembly which is mounted to a moldboard plow. The mulcher bar assembly includes an elongated bar having several chisel-type field cultivators downwardly extending in a soil-engaging position. The orientation of the mulcher bar may be reversed so that rod-like teeth members extending therefrom are in a soil-engaging position for mulching in the spring. Thus, depending upon the orientation of the mulcher bar, the apparatus may be used for either mulching or furrowing.
