  • Slide rail adjustment for grader blade
    Patent number: 6904978
    Abstract: A bearing support arrangement for a grader blade uses short stroke hydraulic cylinders to compensate for wear between slide bearings and slide rails of the grader blade. The cylinders are preferably pressurized by grease and a grease fitting is provided for each cylinder to provide convenient access, to allow service by the operator. Preferably the cylinders are located in a generally closed cavity between the bearing support holder and the slide bearing.

  • Grader moldboard assembly
    Patent number: 6813849
    Abstract: The moldboard support assembly for a motor grader reinforces the rear face of the moldboard by a series of vertical ribs. Upper and lower slide rails are secured to the ribs at a position outwardly of the rear face of the moldboard. This produces a series of gaps between adjacent ribs and between the rear face of the moldboard and the slide rails. These gaps allow material to clear away from the slide rails and thereby reduce bearing contamination of the slide rails.

  • Motorgrader circle drive
    Patent number: 6758286
    Abstract: A circle drawbar assembly uses a series of hydraulic cylinders disposed within the circle member and attached to the drawbar frame to rotate the circle member. These cylinders can also be used to lock the circle member in a desired position. The cylinders preferably are secured to the drawbar frame at a position close to but offset from the axis of rotation of the circle member. The cylinders rotate with rotation of the circle member.

  • Motor grader vehicle control arrangement
    Patent number: 6523617
    Abstract: An intuitive control for a motor grader controls the blade high lift assembly by adjustment of a miniature representation available at the operator's station. This miniature representation allows the direction of adjustment of various hydraulic components to be made by moving the representation in the desired directions. The control is intuitive in that it corresponds to the actual high lift assembly. A similar miniature representation can be used for controlling the steering of the motor grader.
