An agricultural harvester has a chassis, a non-steerable driving front axle and a rear steering axle with a steering mechanism attached to the chassis. A steerable weight transfer axle has a rear steering axle to weight transfer axle linkage assembly linking the steerable weight transfer axle to the steering mechanism of the rear steering axle. The linkage assembly operates to steer the steerable weight transfer axle in coordination with the rear steering axle. The rear steering axle to weight transfer axle linkage assembly has a rear steer axle pivot arm pivotally connected to the rear steering axle and linked to the steering mechanism of the rear steering axle. The rear steering axle to weight transfer axle linkage assembly also has a reversing pivot linked to the rear steer axle pivot arm and to the steerable weight transfer axle.
