Work vehicles are often equipped with operator input devices, which are utilized to control various operational aspects of the work vehicle. For example, movement of a work vehicle implement may be controlled utilizing a joystick device located within the operator cabin of the work vehicle on which the implement is installed. In one common control architecture, rotation of the joystick may modulate one or more control valves. The control valves may, in turn, regulate the flow of pressurized hydraulic fluid to hydraulic cylinders, which then extend or retract to effectuate the desired implement movements. The operator input device (e.g., joystick device) may be included in a larger control system, which further includes one or more components (e.g., the control valves) actuated or modulated by movement of the operator input device. In certain instances, the operator input device may be mechanically linked to the actuated component or components by one or more linkages (e.g., push-pull cables) in a manner physically conveying movement of the input device to the actuated components. In such embodiments, the operator input device may be referred to as a “mechanical” input device, while the larger system containing the input device may be referred to as a “mechanical control system.”
