ABSTRACT:
A belt tensioning system provides an improved starting principle in a large, round baler for agricultural crops. The tensioner comprises two arms, pivotally attached to one another. The front arm is pivotally attached to the baler. The rear arm is pivotally attached to the front arm, and may pivot downward under gravity when the bale chamber is empty of crop material. When pivoted down, the rear arm lowers the top of the bale forming region in the chamber, as defined by the belts. Additionally, the portion of each of the belts making up the rear of the bale forming region are reoriented in a more horizontal orientation, thus providing a forward force to aid in breaking the crop material and urging it forward to start the rolling of the bale.
