ABSTRACT:
The bale pusher mechanism of a round baler has a one-way safety breakaway latch between the push bar that engages the ejected bale and the actuator that operates the push bar. During the pushing stroke of the push bar, the latch cannot unlock, but during the return stroke if the push bar hangs up on the bale for any reason, the relief spring of the latch can yield to allow the push bar to disconnect itself from the actuator and remain engaged with the bale. As the baler is driven forwardly a short distance with the tailgate raised, the unlatched push bar rides harmlessly across the top surface of the bale until it completely clears the bale. In most cases the push bar will then easily relatch itself with the actuator by gravity.
