A system and method are provided for automated cleaning of a loading container of a transport vehicle (e.g., dump truck, ejector, scraper), wherein the loading container includes controllable elements (e.g., hydraulic lift cylinders for a truck bin, an ejector blade) for transitioning between loaded and unloaded states. Characteristics of carryback material remaining in the loading container are estimated during a detected unloaded state of the transport vehicle, wherein whether to initiate an automated cleaning stage is determined based on at least one of the estimated characteristics. Upon determining to initiate the automated cleaning stage, performance of a cleaning routine is automatically directed during or in association with an unloading stage for the loading container via the controllable elements. The elements are controlled during the cleaning routine in accordance with a severity level selected from among various progressively increasing severity levels based on at least one of the estimated characteristics.

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 system, method, and apparatus includes measuring wear of a cutting edge of a blade of a work vehicle. Blade position or calibration measurements are made with or without a cutting edge. A wear condition of the cutting edge is acceptable when the blade position measurement less an acceptable wear to the cutting edge amount is less than a blade calibration measurement. A wear condition of the cutting edge is unacceptable when the blade position measurement less an acceptable wear to the cutting edge amount is greater than a blade calibration measurement. Alternatively, a wear condition of the cutting edge is unacceptable when a blade calibration measurement plus a tolerance margin is greater than the blade position measurement. The wear condition of the cutting edge is acceptable when the blade calibration measurement plus a tolerance margin is less than the blade position measurement.

A work vehicle including a body, an operational frame movable relative to the body about a primary joint, a linkage arrangement configured to adjust a position of the operational frame relative to the body, and a working implement coupled to the operational frame and movable relative to the body. A first sensor is positioned on the body. A second sensor is positioned on at least one of the operational frame, the linkage arrangement, and the working implement. A processor is configured to receive a first signal from the first sensor, where the first signal is representative of a measurement sensed by the first sensor, receive a second signal from the second sensor, where the second signal is representative of a measurement sensed by the second sensor, and determine a measurement error of the first sensor based on the signals from the first sensor and the second sensor.

Machines, calibration kits for machines, and methods of calibrating machines are disclosed herein. A machine includes a chassis, a frame, and a calibration kit. The chassis has a first coupling element and the frame has a second coupling element configured for interaction with the first coupling element to pivotally couple the frame to the chassis. The calibration kit is coupled to the chassis adjacent the second coupling element.
