Abstract: A method of controlling a position of an implement of a machine relative to a frame of the machine is provided. The method includes receiving a target position value for the implement and determining if the target position value falls within a set of whole numbers. The method also includes receiving, via a control element of a user interface, an instruction to reset the target position value to a nearest whole number. The method further includes moving the implement to a position corresponding to the target position value that is reset to the nearest whole number based on the instruction.

Abstract: A method of controlling a differential assembly of a machine is disclosed herein. The differential assembly may be locked by use of a differential lock. The differential lock is adapted to operate in at least one of an automatic mode and a manual override mode. The differential lock is activated and/or deactivated by an automatic differential control system with a manual override mode. The method initiates with activation of the automatic differential control system. Thereafter, the automatic differential control system may be overridden by activation of the manual override mode, while the automatic differential control system continues to be activated. Thereafter, the manual override mode may be deactivated by use of the automatic differential control system based on one or more of a plurality of operational parameters.

Abstract: A system for extracting a motor grader from a location with reduced traction includes the motor grader having articulated front and rear frames supported on front and rear wheels, respectively, and a blade extending from the frame toward the surface underlying the grader. A plurality of blade articulation structures are adapted to articulate the blade relative to the frame. A plurality of sensors are provided and a steering mechanism, power source and control system having a controller. The controller is configured to receive the plurality of signals and perform an extraction procedure to reposition the motor grader. The extraction procedure includes automatic execution of a sequence of operations including a plurality of modification of an articulation angle of the front and rear frames, a steering angle, a position of the blade, a disposition of the blade, propulsion of one or more of the wheels, and direction of propulsion.

Abstract: Systems to control movement of a motor grader include a sensor for providing a bounce signal indicative of a bouncing movement of the motor grader, and a controller programmed with instructions that, when executed: receive the bounce signal from the sensor; analyze the bounce signal from the sensor; determine whether the maximum amplitude of the bouncing movement exceeds a threshold; in response to determining whether the maximum amplitude exceeds the threshold, generate an articulation angle command signal to change an articulation angle of the motor grader; and transmit the articulation angle command signal to change the articulation angle.

Abstract: A method for detecting wear in an implement system of a grading machine includes receiving acceleration information from a sensor connected to the implement system while the grading machine performs a task and estimating an incremental amount of wear in the implement system of the grading machine based on the acceleration information. The method also includes determining a cumulative amount of wear in the implement system of the grading machine and outputting a notification based on the cumulative amount of wear.

Abstract: A technique is directed to methods and systems of an implement lock-out on lever-controlled machines. A lock-out system can monitor the position of an implement and lock-out the implement control(s) when the implement is within a threshold distance to parts of the machine. The lock-out system can generate an implement lock-out to slow, stop, or reduce the force of a hydraulic valve(s) controlling the implement. The lock-out system can use inputs such as electronic fence blade position system data, articulation angles, wheel lean angles, steering angles, ripper positions, mode selection or similar data to determine to generate the implement lock-out. The lock-out system can generate the implement lock-out by a flow supply shutoff to the implement while maintaining pressure to the steering valve. The lock-out system can send visual or audible notifications to alert the operator of the implement's proximity to the machine or of an implement lock-out.
