Abstract
A drift control method for a machine that includes a controller, a cutting tool, a motor having a motor shaft for driving a machine function, a control valve, and an operator control for commanding a machine function. The drift control method includes sensing a neutral position of the operator control, and when in the neutral position, further storing a first position of the motor shaft or cutting tool in the controller, detecting a change in position of the motor shaft or cutting tool with a sensor, determining a direction as a function of the change in position, and hydraulically controlling the motor shaft or cutting tool to the first position.
