  • Patent number: 11898320
    Abstract: A grading machine includes a machine body, a grading blade supported by a circle, a drawbar connecting the grading blade and the circle to the machine body, and a circle drive system. The circle drive system includes a circle drive motor with a motor shaft, a gear box, a gear coupling, and a braking mechanism. The gear box is configured to engage with and rotate the circle relative to the drawbar around a circle axis. The braking mechanism is positioned between the circle drive motor and the gear coupling and is configured to selectively engage the motor shaft.

  • Patent number: 11505912
    Abstract: In accordance with one or more aspects, a circle drawbar for a motor grader has a drawbar frame having two elongated members, and a circle frame that has a surface defined by an inner and outer diameter. The circle frame has a circle gear located radially inward of the inner diameter, allowing the circle frame to be rotatable relative to the drawbar frame around an axis of the circle gear. A platform having a top, bottom, and an edge depends from the drawbar frame and covers the circle gear. A debris remover is connected to the platform and removes debris from the surface of the circle frame as the circle frame rotates.

  • Patent number: 10774503
    Abstract: A motor grader including a frame and a scarifier system coupled to the frame. The scarifier system includes a first pin member and second pin member both coupled to the frame and interconnected to one another. The scarifier system also includes a first and second arcuate drawbar arms in spaced relation and coupled to the first pin member and a carriage. An actuator is coupled to the first arcuate drawbar arm and the second pin member to rotate the carriage about a pivot axis of the first pin member.

  • Publication number: 20150129265
    Abstract: A wear assembly positioned between contacting surfaces a moldboard assembly and at least one of a mounting bracket or a work implement of a work machine. The wear assembly includes a plurality of wear strips having a first surface and a second surface defining a thickness of the wear strip therebetween. The first surface of the wear strip is positioned in a contacting relationship with one of the contacting surfaces, and the second surface of the wear strip is positioned in a contacting relationship with an other of the contacting surfaces. At least one of the first or second surfaces of each of the plurality of wear strips includes a number of recesses infused with a lubricant, such that the number of recesses is formed on a surface area of the wear strip in frictional contact with at least one of the contacting surfaces.

  • Patent number: 8770612
    Abstract: A hitch system for automatically hitching a tractor to a trailing implement is provided. The hitch system may allow an operator that is in a cab of the tractor to remotely connect and electrical system and/or a hydraulic system of a tractor an implement to each other and to remotely secure a hitch pin that connects a tongue of the implement to a drawbar of the tractor. The hitch system may include implement and tractor connector bank assemblies that are respectively provided on the implement and tractor. The tractor connector bank assembly may be moveable in multiple directions for allowing the tractor connector bank assembly to be remotely controlled from the cab of the tractor to align and move into engagement with the implement connector bank assembly.
