Stalk roller assembly for an agricultural system
A stalk roller assembly for an agricultural system includes a stalk roller having a hollow shaft. The hollow shaft has a first end having a first shape, such that the first end engages a guide element. Furthermore, the hollow shaft has a second end having a second shape that engages a drive shaft, such that the first shape is different than the second shape. In addition, the hollow shaft is formed from a single piece of material.
