Abstract
A baler includes a bale chamber and a plunger movable relative to the chamber between a retracted position and an extended position. The plunger is provided with at least two crop engaging elements spaced from one another by a distance defining a clearance opening therebetween, and a drive crank assembly including a drive arm operates to shift the plunger 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 mounted on the plunger for pivotal movement relative thereto about a pivot axis, and a drive link for effecting pivotal movement of the clearing member during shifting of the plunger between the retracted and extended positions.
