Models & Sizes
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.
Mounting
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 rest brackets feature a convenient handle and over-center locking mechanism so you can easily loosen the rest bracket and slide it from side-to-side on the lower bar to the desired location.
The tie-down package for the header features 2" heavy-duty nylon straps, brackets and truck-style ratchets for a streamlined design and quick and easy tightening. Steel hooks and loops are included for secure fastening of the tie-down straps, and these are tool-free adjustable so you can slide them from side to side on the lower bar.
The steel upper rest bar includes three fully supported arms to resist flexing and is adjustable both vertically and horizontally, without tools, to fit any brand grain platform or row-crop header. A storage slot in the upper rest bar is specifically designed for holding an extra cutter knife.
Rear Walking Tandem
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.
Frame
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 a 16’ long tongue but can be equipped with an optional extra-long 20’ tongue with a built-in drop-down design for added clearance. The extendable clevis and spring-lift assist tongue design make hitching to a pickup, combine, or tractor easy and convenient.
The sturdy 6”x4” lower rest bar is pre-arched and trussed to resist flexing and sagging for greater strength and durability.
Extra-height clearance between the axle and ground allows for easy field entry and exit and the trussed lower rest bar adds rigidity to the unit for full-width support. Transport chain, rear-mounted width-adjustable LED lighting package and reflective striping are standard equipment for optimum road travel safety.
Brakes & Tires
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.
Color Options
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.
Accessories
Optional mounting kits are available for John Deere hinged drapers, MacDon FD2-series drapers, Honey Bee drapers and Claas Convio drapers. The John Deere hinged draper kit includes two riser brackets, two axle-mounted bracket assemblies, an upper bar landing pad kit, an extra set of tie-downs, and a drop-down tongue. The MacDon FD2-series draper mounting kit includes three extension arms that raise the upper bar 12".
A longer 20’ tongue is available to fit your mounting and transporting needs in-lieu of the standard 16’ tongue. The extra-long 20’ tongue features a built-in drop-down design for added clearance.
Optional 12" x 48" long upper rest bar landing pads provide a wider landing area for heads with shorter outer feet under each snout.
Other optional accessories include a spare tire, bolt-on pintle hitch, extra set of rest pads, extra set of tie downs and 12” wide upper bar landing pads.
