Some producers think all gravity boxes are the same and are only for hauling grain. Unverferth gravity boxes, however, are much more. We design and build them for transport of all kinds of bulk items such as feed, seed and fertilizer. With an optional unloading auger, a properly matched Unverferth gravity box and running gear is even more versatile.

Features Include:

A low center of gravity and balanced weight distribution provide stable towing
Rugged MIG continuous-bead welding and a one-piece door-side panel enhance sidewall strength and durability
An optional deflector chute is available to permit center-unloading
Unloading is fast and complete with steep-sloped sides and graphite-coated interior
A front ladder is standard for easy viewing of box contents; a rear-mounted, five-rung ladder is optional
A full primer undercoat and durable high-quality equipment enamel topcoat of red or green help prevent corrosion
The rack-and-pinion mechanism permits easy unloading-door opening, even with a full load of high moisture grain
All exposed seams are silicone-sealed to resist corrosion
Capacities range from 400 to 190 bushels to match individual needs
Model 335 features dual compartments for bulk handling versatility
Rounded box corners protect optional tarp against punctures and tears
Optional fitted tarps are available for all models
Optional Deluxe rollover tarp for models 325 and 335 provide quick and easy covering of the wagon's contents
Optional red and amber taillights for added safety.
