  • Patent number: 10779454
    Abstract: A soil penetrating apparatus having an automatic tool (e.g., aerator tine) depth control system and method. The system includes an actuator that sets and controls tine depth, a sensor that monitors tine depth, and a controller that controls the actuator in response to the sensor. In some embodiments, the actuator is a hydraulic actuator, wherein once tine depth is set, flow to the actuator is bypassed. A relief may be provided to allow the tines to lift to a shallower depth temporarily when soil hardness exceeds a threshold. The system may then automatically return the tines to the pre-selected depth once soil conditions permit.

  • Patent number: 6941880
    Abstract: Expandable stinger planting is described in which stinger probes on a boom end mounted frame are positioned for ground penetration on a boom type vehicle. Bottom ends of the probes are shifted between a closed plant receiving, ground penetrating positions; and open positions with bottom ends open to form a plant discharge opening. A receptacle within the probes is open to the plant discharge opening, and receives plants from a magazine. Plants move by a feeder device in the magazine to a release station, where successive plants may be discharged into the plant receiving receptacle. The plant magazine and plant release station are positioned above the plant receiving receptacle such that a plant moved to the release station may drop into the receiving receptacle, to be discharged through the discharge opening. Packers may be provided on the frame to press planting media about the plants.

  • Patent number: 6634306
    Abstract: A transplanter is provided a single centralized pneumatic feeder which will feed anywhere from 2 to 10 or more rows of seedlings at one time. The centralized pneumatic feeder concept allows the transplanter to operate with low velocity movement and still plant large numbers of seedlings. The seedlings are initially in plant trays designed so that the seedlings can be extracted from the bottom of the trays. To simplify seedling transfer, the pneumatic feeder includes an impulse-type extraction system and a pneumatic seedling transfer system is employed. This new system is simple in concept and has only two moving parts per row. This concept makes the transplanter system extremely adaptable to almost any configuration, for example 2-10 or more rows, bare ground fields, mulch covered beds, and even other manufacturer's planters.

  • Patent number: 6341568
    Abstract: An expandable stinger planter is described which includes a base frame and a pivot frame mounted to the base frame for pivotal movement thereon about multiple pivot axes. A stinger comprised of a pair of elongated probes is mounted to the pivot frame and extending to bottom ends. A stinger mounting frame is operatively positioned between the pivot frame and at least one of the elongated probes. An actuator on the stinger mounting frame is operable to shift the bottom ends between a closed position and an open wherein the bottom ends are opened and form a plant discharge opening. An internal plant receiving receptacle within the probes is open to the plant discharge opening at the open position whereby a plant placed in the plant receiving receptacle may be discharged through the plant discharge opening.

  • Patent number: 6158362
    Abstract: An expandable stinger planter is described for attachment to an excavator type boom. The planter includes a frame arrangement that may be releasably secured to the boom, with a stinger depending therefrom. The boom may be selectively operated to drive the probes deep into the ground. The stinger includes a pair of elongated probes that have bottom ends configured to be opened and closed by operation of an actuator assembly. The actuator assembly is selectively operable to shift the probes relative to one another between a closed position wherein the bottom ends are closed together, and an open position wherein the bottom ends are spaced apart from one another to form a plant discharge opening. The probes form an upwardly open internal plant receiving receptacle that is open to the plant discharge opening at the open position whereby a plant placed in the plant receiving receptacle may be discharged through the plant discharge opening as the probes are lifted by the boom.

  • Patent number: 5024172
    Abstract: A seedling holding and dispensing mechanism used on planters having a planting arm which is intermittently extended downwardly into the soil. The seedling holder and dispenser is preferably mounted along the trailing edge of the planting arm. The seedling holder includes a first jaw and a second jaw. The first jaw is preferably mounted to the trailing edge of the planting arm in a fixed position. The second jaw is mounted for movement relative to the first jaw to allow clamping of the seedlings. The second jaw can be pivotally mounted, such as by using a connecting rod which is pivoted torsionally about a longitudinal axis. A proximate end of the connecting rod is adapted to have a lever arm. The mechanism preferably uses retraction and extension position actuators which automatically open the jaws in both the retracted loading position and the extended discharging position.
