This arm is a genuine original component for the round baler's pickup and wrapping system. It connects the actuating linkage to the net or film wrap mechanism, transmitting the motion that initiates and completes the binding cycle. A worn or bent arm causes delayed or incomplete wrapping, leading to bales that do not hold their shape. The original casting and pivot geometry match the linkage's stroke length and bearing surfaces, so no shimming or linkage adjustment is needed during replacement.
