Work machines and methods and systems to control and determine a position of an associated implement are disclosed. An example work machine including a first vehicle component movable relative to a second vehicle component; and a processor to: cause the first vehicle component to move toward a commanded position; predict a first position of the first vehicle component of the work machine using first processes; determine a second position of the first vehicle component using second processes; and in response to a difference between the first position and the second position, to cause the first vehicle component to move further toward the commanded position to correct for the difference.

A system and method for configuring a machine control unit of a construction machine for performing an earth-moving operation, the earth-moving operation comprising a multitude of phases that are to be performed consecutively, the method comprising, by a computing unit: receiving three-dimensional measuring data of a terrain in a surrounding of the construction machine in at least a first detection range, detecting elements of a previous phase of the earth-moving operation based on the three-dimensional measuring data, and configuring, based at least on the detected elements, the machine control unit to at least partially perform the next phase of the earth-moving operation automatically.

An earth moving implement for forming a ditch when towed across ground includes a frame, a tow arm connecting the frame to a towing vehicle, wheels supporting the frame for rolling movement along the ground, and a blade assembly comprising a plurality of earth moving blades. The blades include two main blades arranged to be configured to extend rearwardly in opposing lateral directions from a blade apex of the blade assembly such that the earth moving blades diverge rearwardly from the blade apex, and two outer blades supported on the main blades respectively. The orientation of the outer blades relative to the main blades and of the main blades relative to the frame can all be adjusted while the bottom cutting edges remain level with one another to readily vary cutting width and the lateral direction of earth movement by the blade assembly as desired.

A grader and slope scraping control method and device include a grader having a front frame; a blade mounted on the front frame, an attitude of the blade is adjustable; an actuator for adjusting the attitude of the blade; a first angle detecting member for detecting a first inclination angle in a front and rear direction of the grader relative to a horizontal plane and a second inclination angle in a left and right direction relative to a horizontal plane; a blade detecting member for detecting attitude information of the blade relative to the front frame; and a controller, for obtaining an actual slope angle based on the first inclination angle, second inclination angle and attitude information, and make the actuator adjust attitude of the blade to a target slope angle when the actual slope angle is inconsistent with the preset target slope angle.

A control method is performed in a motor grader, the motor grader including a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. The control method includes detecting a load applied to the blade and revolving, when the detected load is larger in value than a predetermined reference value, the swing circle in such a direction that the blade angle is smaller than the blade angle at the time of detection of that value.

Work machines and methods and systems to control and determine a position of an associated implement are disclosed. An example work machine including a first vehicle component movable relative to a second vehicle component; and a processor to: cause the first vehicle component to move toward a commanded position; predict a first position of the first vehicle component of the work machine using first processes; determine a second position of the first vehicle component using second processes; and in response to a difference between the first position and the second position, to cause the first vehicle component to move further toward the commanded position to correct for the difference.

A motor grader includes a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. A control method performed in the motor grader includes obtaining current topography in front of the motor grader and adjusting the blade angle to an angle in accordance with the current topography by revolving the swing circle.

A control method in a motor grader including a front frame provided with a front wheel, a rear frame pivotably coupled to the front frame and provided with a rear wheel, a pivot mechanism which is provided between the front frame and the rear frame and allows the front frame to pivot with respect to the rear frame, an operation portion, and a sensor capable of detecting whether or not the front frame is at a neutral position with respect to the rear frame includes outputting a control signal for driving the pivot mechanism in response to an operation command in accordance with a state of operation onto the operation portion and stopping output of the control signal in response to the operation command when the sensor detects the neutral position.

A grading implement features a frame with at least one movable section carried by a main frame section. Each movable section is movable relative thereto between a storage position and a working position reaching further laterally outward from the main section to increase a working width of the implement. An underside of each movable section features a respective blade adjustably mounted thereto for selective adjustment between different relative blade positions relative to the movable section. One embodiment features outboard blades on two movable sections, inboard blades on another two movable sections, and a rear blade mounted centrally on the main section behind the inboard and outboard blades. A dust suppression system features spray nozzles distributed across the main frame section behind the blades, and storage tanks mounted atop the main section so that weight of the dust suppression agent provides extra downforce to the blades.

A method and system for non-contact location and orientation determination for an implement coupled with a mobile machine. One example detects an orientation of a recognized feature of an implement with a sensor mounted at a fixed location on the mobile machine. A range from the sensor to the recognized feature of the implement is also determined. In addition, a known operating envelope of the implement coupled with the mobile machine is accessed. The known operating envelope of the implement is then combined with the orientation and the range from the sensor to determine a position of the implement with respect to the mobile machine.
