Two wheel agricultural feed bagger

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 expanding chamber comprised of a horizontal bottom wall, side walls diverging from said passageway and a back wall forming an angle slightly less than 90.degree. with the longitudinal axis of the apparatus;
• a forming chamber having an inlet end and outlet end joining with a leading edge of the expanding chamber and extending forwardly an amount substantially equal to the longitudinal extent of the expanding chamber, 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 along a top portion and along the side portions thereof whereby initially the rotor will force feed stock into the tunnel to completely fill the tunnel and the closed end of the bag and thereafter the pressure of the feed stock forced into the filled tunnel will overcome the loading on the brake means to urge the loading apparatus rearward as the motor maintains the tunnel filled, the expanding chamber accepting newly treated feed stock as the forming chamber shapes the mass of feed stock and the guide means compacting the formed mass as the loading apparatus moves away from the filled end of the bag.
