  • Publication number: 20180175782
    Abstract: A support structure for maximizing solar-panel efficiency and facilitating solar-panel installation reduces the effort of installing solar-panels. The support structure includes a support pole, a primary panel-supporting bracket, an extension arm, and an extension leg. The support pole pivots about a first rotation axis to lower the primary panel-supporting bracket for the solar-panel installation process. The primary panel-supporting bracket is designed to support a variable number of solar-panels depending on the budget constraints and power generation demands. An extension arm raises the primary panel-supporting bracket over the support pole, allowing the primary panel-supporting bracket to rotate about the support pole. The extension leg secures the support structure to the ground and provides a fulcrum for the support pole to pivot about.

  • Patent number: 8256526
    Abstract: An apparatus for positioning a pull type farm implement has an elongated tongue being drawn by a motor vehicle having a vehicle hitch on the rear end thereof configured for attachment to the tongue, the apparatus including a hydraulic hitch mechanism configured to have one end portion attached to the vehicle hitch and an opposite end portion configured to be attached to the tongue of the implement in a non-pivoting manner, the hitch mechanism having at least one hydraulic cylinder for selectively adjusting the lateral position of the front end of the tongue. An optional GPS is operable to detect the position of the tool bar relative to the desired path and repeatedly generate position signals and apparatus for controlling the hydraulic hitch mechanism to adjust the lateral position of the tongue so that the implement follows the desired path of movement in response to the GPS signals.

  • Patent number: 7623952
    Abstract: Embodiments of the present invention comprise a system for positioning a drawn implement having a transverse tool bar being pulled by a vehicle traveling generally along a desired path of movement, the vehicle having a mounting hitch on the rear end thereof where a system hitch is configured to adjust its angular orientation and that of the tool bar relative to the vehicle mounting hitch and a global positioning system having an antenna mounted on the system hitch operable to detect the position of the tool bar of the implement relative to the desired path as the vehicle moves generally along the desired path and generate a signal that is indicative of the lateral position of the implement relative to the desired path and means for controlling the hitch means to adjust the angular orientation of the hitch means and the tool bar so that the implement follows the desired path of movement in response to the global positioning system signals.

  • Patent number: 5524525
    Abstract: A guidance control system for trailing implements attached to a tractor is disclosed. The system can function to steer the implement in a row crop, for example, and can also steer the tractor. A proportional servo valve having a rotatable spool is disclosed, which valve can be controlled to operate in an open center or closed center modes of operation.

  • Patent number: 5170849
    Abstract: A guidance system for the combination of a farm tractor and trailing implement, wherein the guidance system is of the type where the implement is attached to a 3-point hitch mechanism that can be angularly oriented in a horizontal plane by extending one side relative to the other to change the angle of the cross bar relative to the drive axle of the tractor. An alternate embodiment operates with an implement that is attached with a single pull hitch. The system includes circuitry which provides for warning of improper operation and delay means for sounding a warning, provides correction of the position of the implement without over-shooting or hunting by the system. The system utilizes Hall effect sensors for determining the angular position of a wand and or either the implement tool bar or the hitch that is attached to the 3-point hitch of the tractor.
