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 transporting all kinds of bulk items such as feed, seed, and fertilizer. Match your desired capacity gravity box with an appropriate size Unverferth running gear and you'll have a gravity wagon assembly to help you get the job done. Plus, you can add an optional Unverferth unloading auger or conveyor for even more versatility.
Models & Capacities
The rack-and-pinion mechanism for the wheel-operated unloading door permits easy opening, even with a full load of high moisture grain. An optional deflector chute is available to permit center-unloading.
Model 325 features dual side-viewing windows and a sampling door within the main unloading door for convenient moisture and quality testing.
Unloading is fast and complete with steep-sloped sides and a graphite-coated interior.
A front-mounted ladder is standard for easily viewing the hopper contents; a rear-mounted, five-rung ladder is optional.
A full primer undercoat and durable high-quality equipment enamel topcoat of red or green for a long-lasting finish and all exposed seams are silicone-sealed for corrosion resistance. Rounded box corners protect the optional tarp against punctures and tears.
When ordering an Unverferth gravity box with an Unverferth running gear, the gravity wagon assembly comes standard with red and amber taillights for transport safety. This transport light kit is optional on gravity boxes ordered by themselves.
Choose an optionally fitted tarp for an economical design or equip your model 325 with a deluxe rollover tarp that provides a quick and easy covering of the wagon's contents.
