Gravity Boxes - Unverferth Grain Handling
"More Than Just a Gravity Box"
click image to enlarge
Product Overview
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.
Feature Overview
- 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
