The baler uses a single rotary feeder to take crop materials from the center-gathering augers of the windrow pickup and to sweep such materials upwardly and rearwardly through a loading duct into the baling chamber via an opening in the bottom of the latter. A single set of side-by-side crop-engaging forks of the feeder rotates through 360 degrees of travel in a complete cycle of revolution that includes movement up into the bale chamber for presenting the crop materials to the plunger as the latter moves rearwardly in its compaction stroke. Such forks pass through clearance slots in the plunger as the latter wipes crop materials off the forks, but then the forks dip down quickly and temporarily out of the bale chamber into clearance positions as a trailing transverse knife on the plunger comes across the inlet opening of the chamber to sever any dangling strands of crop materials. The forks then pop back up into the bale chamber behind the rearwardly moving plunger until sweeping on down around and into the proximity of the center-gathering augers as their cycle of revolution is completed.
