Abstract: An apparatus and method for mixing fodder with another consumable material wherein a hopper having two compartments is drawn by a tractor or similar vehicle or is self-propelled. Two parallel feeding channels are provided in front of a plurality of animal's stalls in a building and a tractor together with a hopper move between the two feeding channels. There is a discharge device from each of the compartments of the hopper which extend outwardly into the feed channels to receive fodder from one compartment and another consumable material from the other compartment which are mixed together by mixing devices extending outwardly into the feed channels behind the discharge devices. The mixing device is powered by a power take-off shaft from the tractor and rotates to mix the fodder and other consumable material together. The rotation may be about vertical axes or horizontal axes, the latter extending either in the direction of travel of the tractor or transverse thereto.
