The first shaft has a first end and a second end. The first motor is attached to the first end of the first shaft and is configured to rotate the first shaft about a longitudinal axis. The first shaft and the first motor have a longitudinal bore. The second shaft has a first end and a second end, wherein a portion of the second shaft is positioned in the longitudinal bore. The second motor is attached to the first end of the second shaft and is configured to rotate the second shaft about the longitudinal axis. A conveyor assembly includes a first shaft, sprocket, motor, and conveyor, and a second shaft, sprocket, motor and conveyor. An agricultural apparatus includes a tank, a boom, conveyors and motors. ## Claims ### Claim 1 A motor shaft assembly comprising: a first shaft having a first end and a second end; a first motor attached to the first end of the first shaft and configured to rotate the first shaft about a longitudinal axis, the first shaft and the first motor having a longitudinal bore therethrough; a second shaft having a first end and a second end, wherein a portion of the second shaft is positioned in the longitudinal bore; and a second motor attached to the first end of the second shaft and configured to rotate the second shaft about the longitudinal axis. ### Claim 2 (depends on 1) The assembly of claim 1 further comprising a bearing connected to the second end of the second shaft. ### Claim 3 (depends on 1) The assembly of claim 1 wherein there is no physical contact between the second shaft and the first shaft. ### Claim 4 (depends on 1) The assembly of claim 1 wherein there is no physical contact between the second shaft and the first motor. ### Claim 5 (depends on 1) The assembly of claim 1 further comprising a sprocket attached to the first shaft. ### Claim 6 (depends on 1) The assembly of claim 1 further comprising a sprocket attached to the second shaft. ### Claim 7 A conveyor assembly comprising: a first shaft having a first end and a second end; a first sprocket attached to the first shaft; a first motor attached to the first end of the first shaft and configured to rotate the first shaft about a longitudinal axis, the first shaft and the first motor having a longitudinal bore therethrough; a first conveyor attached to the first sprocket; a second shaft having a first end and a second end, wherein a portion of the second shaft is positioned in the longitudinal bore; a second sprocket attached to the second shaft; a second motor attached to the first end of the second shaft and configured to rotate the second shaft about the longitudinal axis; and a second conveyor attached to the second sprocket. ### Claim 8 (depends on 7) The assembly of claim 7 wherein a portion of the first conveyor is aligned side-by-side with a portion of the second conveyor in a plane substantially parallel to the longitudinal axis. ### Claim 9 (depends on 7) The assembly of claim 7 wherein at least one of the first conveyor and second conveyor is configured as an endless belt. ### Claim 10 (depends on 7) The assembly of claim 7 further comprising a first housing wall to which the first motor is attached. ### Claim 11 (depends on 10) The assembly of claim 10 further comprising: a second housing wall; and a bearing connected to the second end of the second shaft and to the second housing wall. ### Claim 12 (depends on 7) The assembly of claim 7 wherein there is no physical contact between the second shaft and the first shaft. ### Claim 13 (depends on 7) The assembly of claim 7 wherein there is no physical contact between the second shaft and the first motor. ### Claim 14 (depends on 7) The assembly of claim 7 further comprising: a third shaft having a first end and a second end; a third sprocket attached to the third shaft; a third motor attached to the first end of the third shaft and configured to rotate the third shaft about the longitudinal axis, the third shaft and the third motor having a longitudinal bore therethrough; a third conveyor attached to the third sprocket; a fourth shaft having a first end and a second end, wherein a portion of the fourth shaft is positioned in the longitudinal bore; a fourth sprocket attached to the fourth shaft; a fourth motor attached to the first end of the second shaft and configured to rotate the fourth shaft about the longitudinal axis; and a fourth conveyor attached to the fourth sprocket.
