ABSTRACT:
Tier pattern selection on the disclosed bale wagon involves periodic rotation of a memory element in the form of a cam plate relative to a cam follower which is connected to means on the bale wagon which will cause the tier pattern selected to be formed. The cam plate is rotated through successive predetermined displacements to successively bring respective peripheral lobes on the cam plate into engagement with the cam follower in a desired sequence. Improved means facilitate accurate rotation of the cam plate and include an electric motor drivingly interconnected to a sprocket mounted on the cam plate shaft, a series of switches and circuitry which interconnects the motor with an electrical power source on the bale wagon. Closing and opening of the circuitry is controlled during normal operation of the bale wagon by certain of the switches so as to cause rotation of the cam plate after each tier selected has been formed and delivered to the load bed of the bale wagon until the cam follower becomes disposed at the next successive position along the cam plate lobes.
