A loading apparatus for loading feed stock into agricultural bags wherein the loading apparatus has a housing with a hopper, a passageway communicating with the hopper and a tunnel communicating with the passageway. The tunnel supports the open mouth of an agricultural bag to be filled. A rotor is drivingly located in the passageway. The rotor and passageway have widths approximately two thirds the width of the tunnel. The tunnel has an expanding chamber, a forming chamber and a guide member. The expanding chamber has a rear wall extending substantially vertically and has side walls diverging outwardly all with the view to accommodating the mass of feed stock received from the rotor in the passageway. The rotor has flanges on the ends within the passageway and mount plural pairs of teeth spaced about the circumference thereof. The relatively short rotor is driven at relatively high speeds, which when combined with the pairs of teeth moves the feed stock rapidly and effectively into the tunnel where it fills the tunnel before discharge into the bag. Brakes are provided on the wheels on the housing which brakes are preloaded so that built-up of pressure of material between the closed end of the bag and the tunnel will advance the loading apparatus to deposit the compacted feed stock in the bag.

In an apparatus for loading feed stock into agricultural bags having a housing with a hopper, a passageway and a tunnel, an agricultural bag expandably affixed to said tunnel and having a closed end closing the mouth of the tunnel, a rotor rotatably mounted in said passageway, means for driving said rotor to move feed stock from the hopper through the passageway and into the tunnel and brake means for resisting relative movement between the loading apparatus and the closed end of the bag, the improvement comprising: said tunnel having an expanded chamber comprised of a horizontal bottom wall, side walls diverging from said passageway and a back wall; a forming chamber having an inlet end and an outlet end, joining with the expanding chamber and extending forwardly thereof, the cross-section of said forming chamber remaining uniform from the inlet end to the outlet end; and a guide means joining with a leading edge of the forming chamber and converging inwardly whereby the rotor will force feed stock into the tunnel to completely fill the tunnel and the closed end of the bag, the pressure of the feed stock forced into the filled tunnel overcoming the loading on the brake means to urge the loading apparatus rearward as the rotor maintains the tunnel and the bag filled. In a loading apparatus for loading feed stock into agricultural bags comprising: a housing having a feed stock receiving hopper, a passageway communicating with the hopper and a tunnel communicating with the passageway, said tunnel supporting the open mouth of an agricultural bag to be filled, the improvement comprising a rotor extending across the width of the passageway; pairs of teeth radially mounted on the periphery of the rotor with axially adjacent pairs of teeth being offset circumferentially on the surface of the rotor; a cross beam on the housing; a plurality of prongs fastened to the undersurface of the cross beam with each prong extending between a pair of teeth and between the adjacent teeth of adjacent pairs of teeth; and a radially extending flange on at least one end of the rotor; a stub shaft extending through the wall of the passageway adjacent said flange and having a mating flange carried by the inner end of said stub shaft; and means for securing the flange on the rotor to the flange on the stub shaft within the passageway whereby said rotor can be removed and serviced without removing the stub shaft from the housing.
