A feed mixer includes a mixer tank with a bottom wall having two curved wall portions defining the bottom of a large main chamber and smaller auxiliary chamber with an elongated ridge therebetween. A rotor having several elongated rotor bars adjacent the outer periphery is supported in the main chamber for rotation in a direction for movement of the rotor bars across the bottom of the main chamber toward the auxiliary chamber. The auxiliary chamber includes a pair of stacked augers adapted for moving material from one end of the tank to the other in opposite directions. Material is thus continuously cycled from the main chamber into a lower portion of the auxiliary chamber where it is moved toward one end of the mixer, forced upwardly into an upper portion of the auxiliary chamber and then directed toward the opposite end of the tank while spilling back into the main chamber for efficient end-to-end mixing of even long stringy hay material.

A material mixer, comprising a mixer tank including forward and rearward end walls, a bottom wall and opposite side walls, said bottom wall including a first relatively large curved wall portion defining the bottom of a main chamber, a second relatively smaller curved wall portion defining the bottom of an auxiliary chamber, and an elongated ridge at the junction of said curved wall portions, a rotor including a plurality of elongated rotor bars adjacent the outer periphery thereof, means for supporting said rotor in said main chamber for rotation in a direction for movement of said rotor bars across said first wall portion toward said auxiliary chamber, said rotor having a diameter such that said rotor bars travel in an arc substantially conforming to and adjacent to said first wall portion, a lower auger, means for supporting said lower auger in said auxiliary chamber adjacent said second wall portion for rotation in a direction to move material axially of said lower auger, an upper auger, means for supporting upper auger in said auxiliary chamber above said lower auger for rotation in a direction to move material axially of said upper auger generally in a direction opposite to the direction of flow of material therebelow by said lower auger, and drive means for rotating said rotor and upper and lower augers.
