    Abstract: A control system for monitoring and managing operation of a rotary disc cutterbar used in an agricultural machine. A controller in the system receives inputs on cutterbar drive power, machine travel speed, and crop cut quality. An operator interface allows suitable operational tolerances to be established. The controller examines crop cut quality, a determination of cut uniformity across the transverse width of the cutting swath, and determines changes in cutterbar drive speed and/or vehicle travel speed, if needed, to maintain crop cut quality within specified tolerances. Controller output may be directed to a display for instructing a machine operator to make necessary adjustments or it may initiate changes in machine subsystems to effect the necessary adjustments automatically.

  • Publication number: 20140069072
    Abstract: An outdoor power equipment unit comprises a self-propelled mower having a hydraulic traction drive system. When engine load exceeds a predetermined percentage of full load, a controller automatically reduces the stroke of a variable displacement pump in the traction drive system to reduce the ground speed of the mower without the operator having to change the position of the traction pedal. This reduces engine load to enhance continued good cutting performance. At any time, the controller can take the same actions to reduce ground speed if an excessively high temperature in a fluid used in a cooling system on the mower is detected, or if excessive loads on the mower decks of the mower are detected, or both.

    Abstract: A windrower with a harvesting header with a crop cutting assembly for severing crop from the ground windrower has a header pitch sensor for measuring a fore/aft pitch angle and a hydraulic system. The hydraulic system moves the header between an operating height and a raised position, and also controls a fore/aft pitch angle. An electronics control module provides an output to activate solenoid valves in the hydraulic system to move the header between the operating height and the raised position and to select a desired pitch angle. When the header moves from the operating height to the raised position, the electronics control module operates the header hydraulic system to move the header to the zero-tilt condition, and upon lowering the header back the operating height, the electronics control module automatically returns the header to the selected pitch angle it was in at the start of the cycle.

  • Patent number: 7854108
    Abstract: An agricultural robot system and method of harvesting, pruning, culling, weeding, measuring and managing of agricultural crops. Uses autonomous and semi-autonomous robot(s) comprising machine-vision using cameras that identify and locate the fruit on each tree, points on a vine to prune, etc., or may be utilized in measuring agricultural parameters or aid in managing agricultural resources. The cameras may be coupled with an arm or other implement to allow views from inside the plant when performing the desired agricultural function. A robot moves through a field first to “map” the plant locations, number and size of fruit and approximate positions of fruit or map the cordons and canes of grape vines. Once the map is complete, a robot or server can create an action plan that a robot may implement. An action plan may comprise operations and data specifying the agricultural function to perform.

  • Patent number: 7765780
    Abstract: Robotic harvesting of agricultural crops. Robot moves through a field first to “map” the field to determine plant locations, number and size of fruit on plants and approximate positions of fruit on each plant. Once the map of the fruit is complete, the robot can plan and implement an efficient picking plan for itself or another robot. A scout robot or harvest robot determines a picking plan in advance of picking a tree. This may be done if the map is finished hours, days or weeks before a robot is scheduled to harvest, or if the picking plan algorithm selected requires significant computational time and cannot be implemented in “real time” by the harvesting robot as it is picking the field. The system harvests according to the selected picking plan. The picking plan may be generated in the scout robot, harvest robot or on a server.

  • Publication number: 20100050584
    Abstract: An in-ground lawn cutting device is disclosed that uses a rotating cord to trim and mulch grass much faster than conventional means. A spool rotates at high speed and extends a weighted cord that cuts grass within a circle. The spool height can be slowly lowered to mulch grass as it cuts. When finished, the cord is retracted and the spool can be lowered at least partly below grade. The device can detect the height of surrounding vegetation and/or the presence of nearby obstructions through reflection or transmission between devices of LASER or other light. The device can issue an audible and/or visual alarm when an obstruction is detected, and/or immediately before and during the cutting. In some embodiments the device can be tilted, the cutting cord can be adjusted in length, and/or a controller is included. The controller can be wireless, hand-held, and/or controlled by a hand-held wireless remote.
