HTS Hopper

“The horizontally fed hog that you (WSM) built for us is performing exactly as you said it would. No more plug-ups, no more hog related down time, no man tending it, maintenance is next to nothing, no more trucking out of long length waste, and the by product produced can be sold instead of us having to pay to truck it away.”
