ABSTRACT:
A method is provided for controlling steering oscillations in a work vehicle having a closed loop GPS based automatic steering system, wherein the closed loop steering system has a default gain and a user defined gain. The method causes the system to automatically apply the default gain when an implement is raised and/or when a steering oscillation has been detected and to automatically apply the user defined gain when the implement has been lowered and/or the GPS track has been acquired.
