Abstract
The disclosure relates to a steering system useful for providing stable control during rear axle steering of harvesters, such as self-propelled windrowers. The steering system utilizes left and right-hand side drive motors, and allows for hydraulic fluid to flow between the left and right-hand side drive motors through crossover lines to regulate a speed differential between wheels when the steering system is actuated into a rear axle steering operation mode.
