Material aerating and mixing machine

A material aerating and mixing machine for the bio remediation of material, said machine comprising a supporting frame defining front, rear, and right and left sides of the machine, ground engaging means mounted on the frame to provide for movement of the machine along the ground, a material elevator supported on the frame at the front of the machine which picks up material to be processed from a stack or windrow of the material and elevates, mixes and aerates the material, a cross conveyor supported by the frame in a position to receive material discharged from the material elevator, the cross conveyor extending generally in a direction from side to side of the machine, means for shifting the cross conveyor from a first position toward the right side of the machine as viewed from the rear for stock turning or truck loading to a second position toward the left side of the machine as viewed from the rear for windrow turning, a discharge conveyor pivotally mounted on the frame on the left side of the machine as viewed from the rear for swingable movement about a generally vertical pivot from a first position generally transverse to the direction of movement of the machine and in line with the cross conveyor to receive material discharged from the cross conveyor for truck loading to a second position at an angle in which the discharge conveyor extends forwardly and outwardly from the left side of the machine to receive material discharged from the cross conveyor for stack turning, the discharge conveyor also being moveable to a third position where the discharge conveyor is positioned along the left side of the machine as viewed from the rear during windrow turning and during transport, and means for independently driving the cross conveyor and discharge conveyor and for driving the cross conveyor in either direction so as to move material from right to left or left to right of the machine as viewed from the rear.
