Abstract
Abstract A baler has a preservative applicator assembly with an improved nozzle array for applying a volatile crop treating fluid to crop material as the crop material is being formed into a bale. The nozzle has a centrally disposed passageway which has a cross-sectional area greater than the minimum sum of the cross-sectional areas of a plurality of fluid dispensing openings in the end of the nozzle. Each of the openings includes a throat and a lip outwardly diverging from the throat. The nozzle array maintains the fluid under high pressure and aids in dispersing the fluid with a high velocity to enhance the retention of the fluid as a liquid while in the nozzle and to promote wide and uniform dispersing of the fluid throughout the crop material during the application.
