An arm load control system for a work vehicle including a controller comprising a memory and a processor. The controller is configured to determine whether a lift arm is in a maximum load configuration based on a position of the lift arm relative to a chassis of the work vehicle and output a control signal to a propulsion assembly of the work vehicle indicative of instructions to adjust a tractive effort of the work vehicle based on whether the lift arm is in the maximum load configuration.

An example work machine control system may include cost factor logic to obtain a cost factor for a resource, cost variable logic to obtain a consumption signal from a consumption sensor indicative of consumption of the resource, fill measurement logic configured to receive a fill signal from a fill sensor, the fill signal indicative of a fill state of a container of an earth-moving work machine, fill target logic to determine a target fill level for the container based on the cost factor, the consumption signal and the fill signal and control logic to generate a machine control signal based on the target fill level.

A work vehicle may include a chassis, a ground-engaging blade, a first sensor, a second sensor, and a controller. The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered and moved in a roll direction. The first sensor may be configured to provide a chassis inclination signal indicative of a main fall angle, a chassis roll signal indicative of a cross slope angle, and a chassis heading signal. The second sensor may be configured to provide a blade inclination signal and a blade roll signal. The controller may be configured to receive the signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.

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 method for machine grade assist includes determining whether user input will cause an implement of a machine to dig below a desired grade. User input to move a stick of an excavator can be blocked and/or delayed using hydraulic pressure so that movement of both the stick and the boom of the excavator can be synchronized to prevent a bucket of the excavator from digging below a desired grade when the stick is moved.

A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller determines a target design terrain indicating a target trajectory of the work implement, and operates the work implement to dump materials on a current terrain sequentially from a nearer side to a farther side of the work vehicle in accordance with the target design terrain. At least a part of the target design terrain is located above the current terrain.

A grading machine may include a machine body, a grading blade, at least one grading blade sensor configured to sense a position and orientation of the grading blade, a drawbar connecting the grading blade to the machine body, at least one drawbar sensor configured to sense a position and orientation of the drawbar, a user interface, and a control system. The control system may be configured to receive an input from the user interface and position and orient the grading blade and the drawbar to one of a plurality of predetermined ditching positions based on the input.

A pitch angle acquisition unit is configured to acquire a pitch angle of a vehicle body. A blade position calculation unit is configured to calculate a position of a blade with reference to the vehicle body. A traveling direction specification unit is configured to specify a traveling direction of the vehicle body based on the pitch angle and the position of the blade.

A system and method for automatically adjusting the pitch of a work implement attached to a work vehicle, wherein the work implement has adjustable wings. The system and method include moving materials with a blade having an adjustable wing located at one end of a center portion of the blade, wherein the blade is operatively connected to the work vehicle and is positionable with respect to the work vehicle in response to an operator command. A commanded position of the blade is identified based on a blade positioning signal received from the operator command transmitted by an operator control device. An inclined position of the adjustable wing with respect to the center portion of the blade is identified. A pitch of the blade with respect to the work vehicle based is automatically adjusted based on the identified commanded position of the blade and the identified inclined position of the adjustable wing.

A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move the work implement along the design surface. The controller determines if slip of the work vehicle has occurred. The controller raises the design surface when the blade tip of the work implement is positioned below an initial target surface when the slip occurs. The initial target surface is the design surface before the occurrence of the slip.
