The patent-pending six-wheel steering design offers sharper turning, greater maneuverability, and the best trailing to handle the heaviest corn heads or drapers. The front 14’ steering radius and 1.4:1 front-to-rear steering connection ratio ensures true tracking performance.


6-Wheel All Wheel Steer (AWST) models are available in 52’, 48' and 42' for hauling the largest corn heads, grain platforms and drapers, including those with stalk stomper attachments.


Patented four-position height adjustable rest brackets provide easy wrench-free adjustment and feature extra-tall backstops that can be flipped down for carrying low-profile headers. The rest bracket features side plates that pivot for use or storage.


The patent-pending rear walking tandem axle design not only provides heavier carrying capacities, but the innovative design keeps all 4 wheels and tires on the ground through uneven terrain. The rear walking tandem axle coupled with the 1.4:1 front steering ratio ensures greater maneuverability and the truest tracking performance down the road.


Heavy-duty greaseable 8-bolt hubs, automotive-type ball-joint steering, spindles with tapered roller bearings and new tires dependably carry all brands of corn heads and grain platforms.


All models are standard with four-wheel electric brakes with two brakes on the front axle and two brakes on the rearmost axle. The brake package includes a breakaway engagement for enhanced transport safety. All models also feature high-capacity IF320/65x15 tires for carrying the heaviest corn heads and draper heads.


The All-Wheel Steer header transport features a highly durable powder-coat finish in your choice of red, green or black for a long-lasting finish that resists corrosion.
