  • Animal feed bagging apparatus
    Patent number: 4949633
    Abstract: A livestock feed bagging machine includes a wheeled chassis having a feed stock receiving trough extending transversely across the front. An auger in the trough distributes the feed stock to a toothed drum which forces ground feed stock through comb fingers into a compression and shaping compartment. Compacted feed stock moves from the compression and shaping compartment through a feed stock discharge section into a flexible bag. An adjustable brake retards the movement of the chassis in a controlled reactive response to the discharge of feed stock into the bag.
