Not all bottom dump hoppers work the same. Our Item 89516 utilizes a full bottom panel that tilts to allow the product to flow and is lifted via fork tubes within the hopper. If a product doesn't flow with gravity, there are other bottom dumping styles. Many of these have fork slots in the upper part of the body of the hopper and are discharged by full bottom or split bottom mechanisms. Be careful about overfilling and interference clogging the fork slots. While all of these do afford a smaller footprint than standard self-dumping hoppers, we also have the Orange Box that affords the smaller footprint, dumps from the front.
