Abstract
An inexpensive square baler is provided with an arcuate baling chamber and a plurality of spaced apart plunger elements shiftable about a kidney-shaped, closed loop path of travel. The baling chamber is partially defined by a horizontal table and a wrapper which have a number of common openings each corresponding to one of the elements. During a return stroke portion of the plunger elements, the latter retract out of the baling chamber and re-enter the chamber between the openings in the table to enable the chamber to accumulate significant quantities of crop materials without interference with the plunger elements during their return stroke portion thereof. A header of the baler includes an auger mechanism having members which urge the crop materials directly through an inlet of the baling chamber without the need for intermediate conveying apparatus, and the members interleave with the plunger elements during the time that the latter pick up crop materials from the table in order to substantially close the inlet of the baling chamber and reduce the amount of crop materials that would otherwise be discharged in a reverse direction through the same.
