Abstract
An overload and overfill protection system for a round baler includes a selectively engageable drive mechanism located between a rotary input member of the baler and an input driven member, such as a sprocket, which drives a pickup mechanism forming a part of the round baler. The selectively engageable drive mechanism includes a fixed drive member mounted to the rotary input member, and a shiftable engagement member mounted to the sprocket for movement between an engaged position for transferring power to the pickup mechanism, and a disengaged position in which power from the rotary input member is not transferred to the sprocket. The fixed drive member is in the form of a shear bolt, which is sheared by an overload force applied to the engagement member when the pickup mechanism is overloaded so as to disable the pickup mechanism. The overfill protection system is in the form of a clutching mechanism interconnected between a movable member of the baler, e.g. the baler takeup shuttle, and a trip member located adjacent the shiftable engagement member for moving the engagement member to a disengaged position when the takeup shuttle is in a position corresponding to a full bale condition for the baler. Movement of the shiftable member to the disengaged position prevents the transfer of power to the pickup drive system, to prevent additional crop material from being supplied to the baler.
