FIELD: agriculture; engineering.SUBSTANCE: group of inventions relates to the field of agricultural engineering. Method for operating a baler with a pressing chamber for pressing a straw-like crop in which the crop is compacted by means of an adjustable pressing pressure and bound through holding material characterized in that the pressing pressure is limited to a maximum value and controlled through a control circuit the reference variable of which is a load characteristic of the holding material. Baler comprises an operating unit for setting a load characteristic of the holding material, a control circuit for receiving said load characteristic as a reference variable and a detected load of the holding material as a feedback variable and outputting an actuating variable representative of the pressing pressure based on said reference and feedback variables, and an evaluation unit for receiving said actuating variable and limiting it to a predetermined maximum value, which reflects a baler-specific maximum load.EFFECT: overload of the holding material and its tearing is prevented, as well as optimization of compacted mass in the form of crop straw.15 cl, 3 dwg |
