A work vehicle is capable of readily knowing an amount of soil built up on a front surface of a blade. A motor grader includes a vehicular body frame, a blade, and an image pick-up apparatus. The blade is arranged between a front end of the vehicular body frame and a rear end of the vehicular body frame. The blade is supported on the vehicular body frame. The image pick-up apparatus is arranged in front of the blade. At least a part of the blade is included within an angle of view of the image pick-up apparatus. A revolving operation of the blade is automatically controlled based on the amount of soil built up on the front surface of the blade.

A system for maximizing productivity of a work vehicle is disclosed. The system includes a first sensor system that generates a first signal output indicative of a height of a material arranged forward of the work vehicle. A second sensor system generates a second signal output indicative of a position and height of a material transport blade coupled to the work vehicle. An actuator system configured to adjust the position and height of the material transport blade. An electronic data processor is communicatively coupled to each of the first sensor system, the second sensor system, and the actuator system. The electronic data processor determines a material flow rate based on the first and second signal outputs, and generates a command signal received by the actuator system to dynamically adjust a plurality of operating parameters associated with the material transport blade to maximize the material flow rate.

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.

Graders and methods of operation thereof are disclosed herein. A grader includes a chassis, a saddle linkage, and a motion measurement system. The saddle linkage is supported for movement relative to the chassis and includes a mount movably coupled to the chassis, first and second arms each movably coupled to the mount, and a crossbar movably coupled to each of the first and second arms. The mount has a lock pin aperture, each of the first and second arms has a locking hole, and the crossbar has a plurality of locking holes. The lock pin aperture may be aligned with one locking hole of the first arm, the second arm, or the crossbar to position the saddle linkage in use of the grader. The motion measurement system is coupled to the saddle linkage and configured to measure movement or position of one or more components of the grader in use thereof.

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.

A grading system for connection to a vehicle having vertically movable arms, the grading system including a grading blade assembly having a frame having a first pivot extending upward, a second pivot extending forward, a blade connected to the frame via the first pivot and the second pivot, a blade yaw actuator and a blade roll actuator, wherein the frame is configured to have the first pivot extend substantially vertically and the second pivot extend substantially longitudinally when the grading blade assembly is connected to the vehicle and the blade and vehicle are in a level position on a ground surface and the vertically movable arms of the vehicle are in a first raised position above a lowest most position.

Systems and methods for adjusting a height of an implement mounted on a body of a vehicle as the vehicle travels over a terrain are provided. Sensor data is received from a set of sensors disposed on the vehicle. A trajectory associated with the vehicle is determined based on the received sensor data. A profile of the terrain is estimated based on the determined trajectory associated with the vehicle. A ditch is detected in the terrain and compensation values for adjusting the height of the implement are determined based on the estimated profile of the terrain to compensate for the detected ditch. One or more control signals are transmitted to one or more actuators for adjusting the height of the implement based on the determined compensation values.
