ABSTRACT:
A method of tensioning the apron of a round baler includes utilizing a pair of springs and a pair of hydraulic cylinders connected between apron take up arms and a tailgate of the round baler in a manner such that the springs normally urge the apron take up arms toward an inner position whereas the hydraulic cylinders resist movement of the apron take up arms from the inner position to an outer position. The hydraulic cylinders provide a primary source of apron tension and the springs provide a secondary source of apron tension so that, during bale formation, the apron tension generated by the hydraulic cylinders increases while the apron tension generated by the springs remains substantially constant.
