Abstract: A bale and grain feeder device includes an elongate conveyor and table structure which is mounted on the mixer-grinder vehicle chassis. The conveyor and table structure may be positioned to discharge slabs of hay and loose grain into the hammer mill of the mixer-grinder vehicle to permit such material to be chopped or ground into small pieces. A feed chute positions the baled hay on a conveyor and table structure to permit conveyor chains having paddles thereon to rip away portions of the bale. The feed chute may be removed for use with small grains or ear corn. A slab feeder roll cooperates with the conveyor paddles to convey the slabs of hay along the table where the hay or grain is directed to the hammer mill by paddles. A finger roll is used in the inlet area to precisely control the rate at which the bale is fed downwardly.
