A removable grain hopper is a multifunctional option. The option can be stowed away nicely under the chassis and is a great solution while transporting more than just grain, like pallets, big bags... Are you interested in this option, but would like to install it on an existing walking floor trailer? That is possible! You can order the removable grain hopper through our PARTS department and simply install it on your current STAS walking floor trailer. --> parts@stas.be 💪 | STAS Trailers
