Description

The Unverferth RoadRunner HD is engineered for farmers and custom harvesters who demand heavy-duty header transportation and smooth highway travel. This all-welded, six-wheel transport features a tricycle-style front end and tandem rear axles, offering stability, maneuverability, and safety for hauling your combine’s high-value grain platform, draper head, or corn head.

Available in 52′, 48′, 42′, 36′, and 30′ models, the RoadRunner HD is built with tubular steel construction and diagonally welded cross braces for maximum durability and rigidity. The HD-52, HD-48, and HD-42 utilize larger 14″ x 4″ frame tubes, while the HD-36 and HD-30 feature robust 12″ x 4″ frame tubes—delivering strength for long hauls and heavy loads up to 14,000 lbs.

The RoadRunner HD offers advanced operator convenience with tool-free, six-way adjustable header rest pads, a streamlined tie-down package with heavy-duty straps and ratchets, and an upper rest tube that doubles as convenient storage for extra cutter bars. The adjustable tongue makes hooking up to any towing vehicle easy, while full-wrap fenders and industry-standard LED lighting provide protection and visibility on the road.

With multiple size options and mounting kits for John Deere, Claas, or Honey Bee draper heads, the Unverferth RoadRunner HD streamlines your harvest operation—ensuring safe, timely, and efficient header transport wherever your work takes you.
