Abstract
An agricultural baler for making cylindrical bales of crop material having a sledge assembly moveable between bale starting and full bale positions. The sledge assembly includes a plurality of rollers which cooperate with an apron to define a bale forming chamber. A dispensing mechanism is carried on the sledge assembly for dispensing web material into the bale forming chamber whereupon it is wrapped circumferentially around a cylindrical package of crop material. A net supply assembly is associated with the dispensing mechanism to provide net for feeding into the bale chamber via the dispensing mechanism. Included along the feed path of the net is a net severing assembly for cutting the net after it has been wrapped around the cylindrical hay package. The net severing assembly includes a free falling cutting element for operatively engaging the net prior to entry into the chamber. A control arrangement prevents the severing assembly from operating at a time when it would have a deleterious effect on baler operation.
