  • Patent number: 4067298
    Abstract: A hay hauler and feeder includes a platform of wood framed in steel with demountable racks which, when in place, serve as self-feeders, on sides, front and rear. Feeding stations are divided with steel bars angled to the right or left to limit and control hay withdrawal in order that the contents may be fed with minimum wastage. The hauler-feeder is mounted on a single axle mounting with four wheels in tandem which are capable of oscillation for maximum uniform weight distribution and a trailer jack at the front tongue for leveling when field-feeding.
