Unverferth ROADRUNNER 48' MODEL 548

FASTER TRANSPORT

The tricycle front wheel design with standard plastic fenders facilitates maneuvering for tighter turns and features a torsion-flex suspension for the safest and most stable towing.

MODELS & SIZES

Models are available in 48', 42', 36', and 30' for hauling the widest variety of corn heads, grain platforms, and draper platforms, 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 AXLE DESIGN

The tandem rear axle design features 6,000 lb. axles and rubber cushioned suspension for the smoothest ride.  The tires on the rear axle are set at a 93” tread width for increased clearance from the head.

FRAME

The tongue is length adjustable from 57” to 81” and features a telescoping clevis hitch that makes hitching to a pickup, combine, or tractor quick and easy. The tongue can be rotated 180° and stored underneath the frame for more compact storage.

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

The 48’ model is standard with four-wheel electric brakes and the 42’ model is standard with two-wheel electric brakes.  Two- (36’ & 30’), four- (42’, 36’ & 30’) and 6-wheel (all models) brake packages are available as options.  Brake packages include a breakaway engagement for enhanced transport safety. 

COLOR OPTIONS

The RoadRunner 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 12" x 48" long upper rest bar landing pads provide a wider landing area for heads with shorter outer feet under each snout.

An optional mounting kit is also available for the MacDon FD2-series draper heads, including three extension arms that raise the upper bar.

Other optional accessories include a spare tire, bolt-on pintle hitch, 2 5/16” ball hitch conversion kit and a VIN package that includes a license plate holder, rear running lights and reflective decals.
