Abstract
A method of manual control neutral drift correction for a work vehicle is characterized by the steps of: sensing a position of a first manual control using a first position sensor when an activation switch is activated, wherein the first position sensor generates a first input signal; sending the first input signal to a controller; retrieving a stored first manual control neutral position value from a memory unit; calculating a first corrected manual control neutral position value using the controller, wherein the first corrected manual control neutral position value is calculated using the first input signal and the first manual control position value; and utilizing the first corrected manual control neutral position value to generate a first control signal for operating a first electro-hydraulic valve, wherein the first control signal is generated by the controller to operate the first electro-hydraulic valve to effect movement of a first assembly.
