ABSTRACT:
A round baler having a shiftable repositioning member for moving a completed, discharged bale of hay away from the baler is provided with an interlock mechanism for preventing movement of the repositioning member until such time that the bale has been discharged from the chamber. A sensor is located on a side of the baling chamber to determine the absence of a bale, and preferably takes the form of a rounded element biased toward a position normally protruding into the chamber. The presence of a bale within the chamber causes the element to shift outwardly and thereby close a valve interposed in a hydraulic circuit for providing motive fluid power to a piston and cylinder assembly that, in turn, drives the repositioning member. Once the completed bale has been discharged from the baling chamber, however, the element shifts under the bias of a spring toward its normal position protruding into the chamber to thereby close the contacts of a magnetic reed switch and open the hydraulic valve so that the repositioning member may then be activated to shift the bale away from the baler.
