A vehicle grade control system and method of controlling an implement position of a motor grader moving along a path of a surface. The motor grader includes a frame supported by wheels and an implement adjustably coupled to the frame. The control system includes a processor and a memory configured to receive a grade target to grade the surface to a desired grade with the implement based on the grade target. Surface irregularities of the surface in a path of the motor grader are located. An angle of the frame is determined based on the located surface irregularities and a difference between the identified angle of the frame and the grade target is determined. A position of the implement with respect to the frame based on the determined difference is identified and the surface is graded with the identified position of the implement.

A vehicle grade control system and method of controlling an implement position of a motor grader moving along a path of a surface. The motor grader includes a frame supported by a ground engaging traction device and an implement adjustably coupled to the frame. The control system includes a processor and a memory configured to receive a grade target to grade the surface to a desired grade with the implement, based on the grade target. A front image sensor provides images of a front surface profile, an implement image sensor provides images of collected surface material on the implement, and a rear image sensor provides images on a rear surface profile. The surface is graded by adjusting a position of the implement based on the images provided by each of the front image sensor, the implement image sensor, and the rear image sensor.

A rear frame for a motor grader includes a pair of arms that are disposed equidistantly from a mid-plane. Each arm has a front portion, a rear portion, and a mid-portion located between the front and rear portions. The front portion of each arm is configured to pivotally couple with a front frame of the motor grader. The rear frame also includes a ripper mounting arrangement, a bumper, and a torque resisting member. The ripper mounting arrangement is located at a rear end of the rear portion of each arm. The bumper is laterally disposed with respect to the mid-plane and rigidly attached to a position on the rear portion of each arm located adjacent the rear end of the rear portion of each arm. The torque resisting member is laterally disposed with respect to the mid-plane and rigidly attached to the mid-portion of each arm.

A mounting assembly for a chock block for a wheel of a machine includes a first bracket configured to be attached to a pocket of a ripper of the machine. The first bracket includes a central plate and two side plates extending from the central plate. The mounting assembly also includes a second bracket configured to be attached to the first bracket. The second bracket includes a pair of support rods extending therefrom. The pair of support rods is configured to removably mount the chock block thereon.

The control device is a control device that controls a drawbar attached to a main frame of a grader, in which a movement of the drawbar is generated by at least three actuators, and the control device controls, based on an output signal from one operation lever having at least three degrees of freedom, the plurality of actuators such that a movement of the one operation lever corresponds to the movement of the drawbar.

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.

A ground engaging tool control system including a first sensor system, a second sensor system, a first actuator system, a second actuator system, and an electronic data processor. The first and second sensor systems detect respective positions of a first ground engaging tool and a second ground engaging tool. The first actuator system is coupled to the first ground engaging tool and the second actuator system is coupled to the second ground engaging tool. The electronic data processor determines a target grade profile and generates two or more control signals to adjust target positions of the first ground engaging tool and the second ground engaging tool. The target position of the second ground engaging tool is determined based on at least one of a position of the first ground engaging tool or the comparison of a current grade profile and a desired grade profile.

A work vehicle grade control system for a vehicle having a plurality of pneumatic tires, a frame supported by the plurality of tires, and a grader blade configured to move with respect to the frame to grade a surface. The grade control system includes an actuator operatively connected to the grader blade, wherein the actuator is configured to move the grader blade with respect to the frame based on one or more tire pressures. The grade control system includes control circuitry configured to identify a current grade of the surface; identify a position of the grader blade with respect to the surface; identify the one or more tire pressure of one or more of the plurality of tires; and adjust the position of the grader blade with respect to the frame based on the identified current grade and the identified tire pressure of the one or more plurality of pneumatic tires.

The present disclosure relates to a leveling control method, device and system, a motor grader. The leveling control method includes: acquiring elevations of a current position of a blade of a motor grader and a target position, and a movement speed of the motor grader, wherein the target position is on the ground with a certain horizontal distance from the current position along a movement direction of the motor grader; determining a movement time of the blade from the current position to the target position from the horizontal distance and the movement speed; determining a lifting speed of a lifting cylinder from an elevation difference between the elevation of the target position and the elevation of the current position and the movement time; and controlling the lifting cylinder to adjust the blade to move from the current position to the target position according to the lifting speed.

A controller specifies a diagnosed portion to be diagnosed in a motor grader based on candidate information of an abnormality candidate in the motor grader, specifies a first sensor connection position of a diagnosis sensor for diagnosis of the diagnosed portion, and controls a display apparatus to display position information of the first sensor connection position.
