Abstract
A drive system for a pull-type swather or windrower in which a sensing device senses the side-draft of the swather under operating conditions. The sensing device indicates to a compensating device which is operable from the sensing device whether to increase, decrease or leave unchanged the rotational speed of drive wheels which are provided on the swather and powered by a power plant. The drive wheels act to keep the swather in an effective cutting position substantially transverse to the longitudinal axis of the tractor.
