B&W Draw Bar part # TS35100B is an accessory for the Tow & Stow receiver hitch that allows the user to pull agricultural equipment (like a seed / fertilizer spreader) that attaches using a hitch pin instead of a ball. Simply put the Tow & Stow in the stow position and use the two included pins to attach the draw bar to the unused holes in the Tow & Stow receiver.
