A control system for a work vehicle has a controller configured to adjust first and second actuators for moving first and second sides of an implement relative to the work vehicle. A first operator control provides a first incremental input to the controller corresponding to a first incremental adjustment of the first actuator effecting a prescribed change in position of the first side of the implement. A second operator control provides a second incremental input to the controller corresponding to a second incremental adjustment of the second actuator effecting a prescribed change in position of the second side of the implement. At least when in a manual control mode, the incremental change in position of the first side of the implement is independent of the incremental change in position of the second side of the implement.

In a work vehicle, such as a motor grader, having at least one actuator for positioning a component, an operator control system includes at least one controller configured to control the at least one actuator, and a control movable through a range of motion and having at least two detents, at least one located on each side of a neutral position of the control. The at least one controller is configured to control the at least one actuator based on positions of the control as the control is moved through its range of motion, and correlate at least one input signal from the control when at least one of the detents with at least one reference position of the component.

A system and method configured to select a control configuration for a hydraulic fluid system. The system includes a controller having at least one sensor and a processor. The controller is configured to sense a feed pressure and a return pressure of a fluid within the hydraulic fluid system and a speed of a driven set of wheels and a speed of an idle set of wheels. The driven set of wheels are drivingly coupled to an engine, and the idle set of wheels are drivingly coupled to the hydraulic fluid system. The controller is further configured to select a control configuration for the hydraulic fluid system based on a ratio between the feed pressure and the return pressure, and further based on a ratio between the speed of the driven set of wheels and the speed of the idle set of wheels.

A system and method that includes a device that is used in a particular method to install bearings into a lift cylinder yoke bore. The device includes use of a hollow bore hydraulic push cylinder that maneuvers a push plate along a threaded rod. The push plate sinks or sets into the bearing and applies pressure through the movement of the hydraulic push cylinder to place the bearing into a fit position without the abrasion that is usually associated with the installation of bearings into the lift cylinder yoke bore. The threaded rod attaches to a threaded bushing that is inserted into the bore and secured with the use of a pin. The threaded rod extends out of the bore opening and allows for the attachment of a bearing, push plate, hydraulic push cylinder, washer and nut.

Embodiments of the present invention are directed to systems for performing non-contact based determination of the position of an implement. In one embodiment, a non-contact based measurement system is used to determine the relative position of an implement coupled with a mobile machine. The geographic position of the mobile machine is determined and the geographic position of said implement based upon the geographic position of the mobile machine and the position of the implement relative to the mobile machine.

A moldboard rail cleaner for removing debris from a rail of a work machine having a tilt frame housing defining a first cavity. The work machine has a wear insert positioned within the first cavity and adapted to slide along the rail as the rail moves along a rail axis. Further, a sub-housing may be coupled to the tilt frame housing and define a second cavity. Finally, a wiper is disposed at least partially within the second cavity, the sub-housing configured to bias the wiper into contact with the rail.

A method of maintaining a roadway (2) during transfer of a load from a first location to a second location by a motorised vehicle (1) is described. The vehicle (1) may be a dumper truck and has a retractable blade (8) movable relative to the vehicle (1) between a retracted position (FIG. 1) and a working position (FIG. 2). The load is transferred in the vehicle (1) from the first location to the second location along the roadway (2), the blade (8) is moved to the working position after dumping the load and on the return journey the vehicle (1) acts as a grader to smooth undulations and ruts. The blade (8) is pivotally mounted and located between the front axle (5) and the rear axle (6, 7) and does not extend beyond the width of the vehicle. Unmetalled roadways on construction sites, quarries and mines may be maintained in good condition without the need to employ additional vehicles or hire separate grader vehicles.

The at least one controller is configured to control the at least one actuator based on positions of the control as the control is moved through its range of motion, and correlate at least one input signal from the control when at at least one of the detents with at least one reference position of the component.
