Unverferth Header Transports

The Fieldrunner header transport is much more than just a running gear with rails. It has the most versatility for matching any style header or grain platform of all traditional header transports and is perfect for shorter road trips moving from field to field.

From the patented rear-oscillating axle that keeps all four wheels in full contact with the ground, even over the roughest terrain, to the wide-spaced support beams that provide greater stability and balance, and the standard-equipment new tires, the Unverferth Header Transport is much more than just a running gear with rails, it's the right tool for the job.
