<p>A baler includes a bale chamber (10) and a plunger (20) movable relative to the chamber between a retracted position and an extended position. The plunger (20) is provided with at least two crop engaging elements (26-38) spaced from one another by a distance defining a clearance opening therebetween, and a drive crank assembly (50) including a drive arm (40) operates to shift the plunger (20) between the retracted and extended positions in a series of operating cycles. A clearing assembly is included for clearing crop materials from at least a portion of the clearance opening in the plunger. The clearing assembly includes a clearing member (62) mounted on the plunger (20) for pivotal movement relative thereto about a pivot axis (65), and a drive link (80) for effecting pivotal movement of the clearing member during shifting of the plunger (20) between the retracted and extended positions.</p> |
