ABSTRACT:
An overrunning sprocket for the bale pickup mechanism on a bale wagon is disclosed wherein the drive sprocket for transferring rotational power from a drive shaft to the elevating mechanism in the bale pickup is rotatably mounted on the drive shaft for rotation independently thereof. A drive lug welded to the drive sprocket is engageable with a second drive lug welded to the drive shaft to limit the rotation of the drive sprocket relative to the drive shaft and permit rotational power to be transferred from the drive shaft to the elevator. The drive sprocket is free to overrun the drive shaft by substantially one revolution to permit the elevator to be accelerated by the picking up of a bale from the ground when the ground speed of the bale wagon is greater than the speed of the elevator in the bale pickup mechanism.
