  • Patent number: 10687452
    Abstract: The instant invention is a machine/implement used for soil preparation, fertilizing and seeding intended for farming and gardening that mounts on a standard three point hitch and is powered by a tractor's power-take-off (PTO). The implement integrates the processes of ground breaking, tilling, fertilizing and planting in one adjustable unit. The adjustments include the spacing and depth of the ground cutting and tilling blades and the openings of the fertilizing ports to prepare the ground for planting in defined strips leaving the majority of ground only lightly disturbed. To achieve these goals, the apparatus is comprised of two frames, a lower one that contains the blades that break the ground crust ahead of the tiller tines that grind the soil into finer particles for planting. The lower frame also has a rear flap that levels and marks the tilled soil and also supports seed boxes with a mechanism that allows the seeder/seeders to set seed at a constant depth on uneven ground.

  • Patent number: 9546461
    Abstract: A snow thrower having a reverse shut-off mechanism configured to deactivate voltage supplied from a power source to a motor that rotates an auger assembly. The reverse shut-off mechanism deactivates the voltage supplied in response to the snow thrower being moved or rolled in a reverse direction. Upon movement of the snow thrower in a forwards direction to clear snow or other debris, the shut-off mechanism reactivates voltage supplied from the power source to the motor that rotates the auger assembly. This allows the snow thrower to conserve power and/or fuel when the snow thrower is not being used to clear snow or other debris.

  • Patent number: 9290905
    Abstract: The remote excavator tool fastens to a robotic arm on a remotely controlled robotic platform that includes a track drive. The tool uses high speed tilling elements rotating at about 1500 rpm to dig, efficiently, a trench using a small amount of power. The tilling elements are hardened steel, rotating counterclockwise to a conventional tiller. The tilling elements are symmetrically mounted on a polygonal shaft, and include right and left multiple couples of paired facing disks with staggered curved tines, where the tines are thick and have tapered hardened edges. Round brushes are interspaced between couples. The loosen soil is pushed forward and to the sides to help protect the robotic platform and maintain control of the tool especially as the rate of the excavation partially depends on the characteristics of the material being excavated.

    Abstract: A powered hand tool is adapted to use a variety of interchangeable rotary tools to assist in outdoor activities. Either of two basic tool designs can be utilized for activities including garden tilling, brushing and cleaning, auguring or post hole digging, and auto finishing and polishing. In one embodiment, an adjustable shroud is utilized along with a tiller construction to change the viewing angle of the working tiller tines to facilitate use by operators of different heights, including a kneeling position. The ability to utilize tow torque and low speed assists in avoiding accidental damage to underground wires and, if encountered, the reversibility of the drive assists in untangling the wires.

A wheel apparatus can attach to a tilling machine, such as by attachment to a drag bar, in a transport position or a storage position. In the transport position, the wheel apparatus can maintain tiller tines of the tilling machine above the ground surface with the weight of the tilling machine supported on the wheel apparatus, thereby allowing the tilling machine to be rolled for transport. In the storage position, the wheel apparatus can be attached to the drag bar, whereby both the tiller tines and the wheel apparatus rest on the ground surface to provide stability to the tilling machine. During operation the wheel apparatus can be removed from the tilling machine.

  • Publication number: 20100139936
    Abstract: A tiller with chassis, pair of handles, and tines, wherein simultaneously raising one handle and lowering the other twists the chassis to lower one tine and raise the other. The tines comprise pairs of blades, each blade having a pair of upturned tips. The height of tines is adjusted by adjusting the support for wheel means. The tiller is supported by an arm having a single ground engaging wheel means, pivoting the arm and locking in position to adjust the height of the tiller. The tiller includes a third handle located along its chassis. The chassis is formed from two longitudinally split components. A blade cover for the tiller is thin and curved to lie in an arc spaced from the rotating tips of the tines. An attachment for the tiller has a V-shaped tip and shaped to form a furrow.

  • Patent number: 7669667
    Abstract: A walk aerator comprises a frame supported by a plurality of ground engaging wheels, the frame carrying a coring head having a plurality of side-by-side tine assemblies. The wheels define a wheelbase which is substantially equal to or less than the width of a coring swath and the wheels are located in advance of the coring head to keep the wheels from passing over the holes or soil cores left in any preceding coring swathes formed by the aerator. The vertical position of the coring head is adjustable up and down as the ground contour changes to keep hole depth substantially constant. The tine assemblies are reciprocated by a single crankshaft driven by a single pulley, the crankshaft being assembled from multiple crank arms that are splined and bolted together. Sealed bearings connect drive arms that drive the tine assemblies to the crankshaft. The crankshaft can be disassembled to allow the sealed drive arm bearings to be replaced. Integral core deflectors are used on the drive arms.

  • Patent number: 7644779
    Abstract: A walk-behind power unit is configured to detachably mount a counter-rotating powered drum work implement on a centrally pivoted implement carrier. The pivoting of the implement carrier from a central position to either side causes the discharge of the powered drum to be located on a desired side of the work implement. The work implement can also be positioned to discharge forwardly from the powered drum member. A lift apparatus is provided to be cooperable with an associated set of support wheels to affect the positioning of the powered drum member between a lowered operative position and a raised transport position. The powered, counter-rotating drum member can be either a rotatable broom or a power rake. In the broom configuration, the lift apparatus can move the lid member, after first unlatching the lid member from the frame of the work implement, to fix the lid in an opened position.
