An extractor apparatus for moving grain from a grain bag has a frame mounted for movement along the ground in a rearward direction, and an upright oriented main auger attached to a rear end of the frame. A knife extends rearward from the main auger to cut the grain bag. A feed auger extends horizontally right and left of the intake end of the main auger, and is configured to auger grain to the intake end of the main auger. A disintegrator shaft is mounted rearward of the feed auger and parallel to the feed auger, and a plurality of disintegrator blades are spaced along a length of the disintegrator shaft and extend outward from the disintegrator shaft. A drive system is operative to rotate the main auger, feed auger, and disintegrator shaft. The length of the disintegrator shaft can be adjusted to suit the width of a particular bag.
