ABSTRACT:
A control arrangement, especially for use with a track supported implement, having an elongated beam with carriages at the opposite ends supported on respective tracks in which pick-up elements on at least one of the carriages are sensitive to movement of the respective carriage in a horizontal plane and about a vertical axis on the respective track. The pick-up elements are longitudinally spaced on the curve and supply respective signals to a comparator which emits a control signal which varies as the difference between the pick-up signals varies. The control signal is employed for developing an influence on the beam tending to restore it to the condition of parallelism with itself.
