  • Patent number: 11558991
    Abstract: An agricultural planter includes systems, methods, and apparatuses for maintaining down force pressure at row units of the planter. The row units may include an electric linear actuator connected to linkages of the row units to maintain a down force pressure for the row unit. The linkage may also be removed and replaced with a strut or like mechanism to apply a direct down force pressure to components of the row unit. One or more sensors can be included to obtain information related to the ground to automatically adjust the amount of down force provided based upon a ground characteristic in order to maintain a substantially uniform furrow depth.
    Type: Grant

  • Patent number: 10064323
    Abstract: An agricultural implement includes the use of one or more electromechanical hydraulic cylinder assembly in place of hydraulic cylinders. The assemblies may take various forms for actuation, and can convert an electric power source to hydraulic power for use on or with the implement. A control system is also provided for connecting to a tractor to provide control information to the assemblies or to a central hydraulic supply via a ISOBUS that rebroadcasts input controls from a source, such as a tractor used in conjunction with the agricultural implement.

  • Patent number: 9474201
    Abstract: An agricultural planter includes a plurality of row units attached to a toolbar. The row units include seed meters for receiving, singulating, and dispensing seed or other particulate. The seed meters include a circular seed disc with a seed path for receiving the seed in the seed meter housing. Integrated with the seed disc is a motor that is housed within the seed meter housing and that includes a rotatable portion being attached to the circular disc such that the two rotate in tandem. The integrated motor can be positioned within an interior portion of the circular seed disc such that the width of the disc and motor combination is kept to a minimum.

  • Publication number: 20150198719
    Abstract: A positioning system and method of determining a position of a mobile unit is provided. The system and method include the use of radio frequency signals transmitted between the mobile unit and multiple base units having known and fixed locations. The signals will be transmitted from and returned to the mobile unit to determine a phase shift of the signal in order to determine the distance between the two. The process can be repeated between the mobile unit and each of the base units in order to acquire a continuously updated location of the mobile unit relative to the base units. Additionally, optics and GPS can be included to acquire additional distance readings for comparison and to more accurately determine the location of the mobile unit.
