Abstract
An apparatus for controlling a lateral position of a first member on a hitch of a work machine. A first processing device receives a first signal indicative of a desired turn radius of the work machine and transmits a first desired hitch position as a function of the first signal. A second processing device receives a second signal indicative of an actual hitch position and also receives the first desired hitch position. The second processing device transmits a first error as a function of the second signal and the desired hitch position. A controller receives the first error and transmits a second error as a function of the first error. A first member modulator receives the first error and transmits a first activation signal as a function of the second error. The first activation signal controls the lateral position of the first member.
