Abstract

A round baler having a main frame including opposing sidewalls, and an apron assembly comprising crop engaging elements disposed between said sidewalls for defining a bale forming chamber having a generally cylindrical shape with a transverse inlet. The crop engaging elements move along a path having an inner course contiguous with a major portion of the fixed periphery of the cylindrical chamber. The baler also includes a pickup assembly for feeding crop material to the chamber through the inlet whereby crop material accumulated in the chamber is engaged by the crop engaging elements and formed into a compacted cylindrical package. A supply of net material is selectively dispensed via a dispensing assembly into the chamber for wrapping the periphery of the formed cylindrical package of crop material in the chamber. A supply of twine fed to a twine dispensing assembly is also selectively dispensed into the chamber for wrapping the periphery of the cylindrical package of crop material. Cutting means is adapted to severe the net under conditions where the twine is being dispensed into the chamber.
