  • Patent number: 11946231
    Abstract: An improved system and method for controlling turf grading equipment is described. The system comprises a turf grading device wherein the turf grading device is moved longitudinally over an area and the turf grading device comprises a left side and a right side with each side being able to independently move vertically and in concert provide a motion of pitch and yaw. The system includes a control system wherein the control system controls movement of the left side and the right side independently. The control system comprises a controller interface capable of selecting between a manual override mode and a module selection mode wherein the module selection mode selected from a grade adjust laser mode, a grade adjust autograde mode, a grade adjust autodepth mode and a grade adjust slope mode.

  • Publication number: 20210372082
    Abstract: A towable attachment leveling apparatus, typically used on tractors, skid-steer, and other vehicles, with ability to independently vary the inclination of each side of an attachment, such as a turf box, about a centerline axis running substantially parallel to the longitudinal direction of travel during use, as well as adjust the vertical elevation of the attachment and allow for additional adjustments to the pitch and/or yaw of the attachment.

  • Patent number: 11098461
    Abstract: A turfplaner is described comprising a rotational elongated cutter capable of independently altering a cut height of the rotational cutter based on a deviation between cut height and a desired cut profile. A hierarchical controller is in functional communication with the lift mechanism and a laser or GPS guidance system. The laser or GPS receiver is capable of receiving the planer laser beam or GPS signal and the hierarchical controller is capable of determining and minimizing a deviation between the cut height and the desired cut profile based on the laser or GPS receiver location relative to the planer laser beam or GPS signal. At least one autograde device and an autodepth device are in functional communication with the hierarchical controller to activate either on grade, below grade, or above grade control mode.

  • Patent number: 8555992
    Abstract: An improved turfplaner system for leveling an area to a predetermined height is described. The turfplaner system includes a device capable of being transported over an area. The device includes a rotational elongated cutter with a first side and a second side and a control mechanism capable of independently altering a height of the first side of the rotational cutter and the second side of the rotational cutter relative to a predetermined height over the area.
