ABSTRACT:
The invention relates to a modular stalkroll for a corn head on a corn harvester. The apparatus consists of a drive shaft, fabricated stalkroll and a front auger. The drive shaft has several milled regions and a tapered region. The fabricated stalkroll has an upper and lower hub. The lower hub is inserted onto the drive shaft and is in contact with the tapered region. The upper hub has a drive shaft receptacle which receives the milled region of the drive shaft. The upper hub also has a female receptacle for receiving the front auger. A retaining bolt is inserted through the front auger and through the upper hub so as to clamp the front auger and fabricated stalkroll to the drive shaft. The fabricated stalkroll can be replaced by removing the single retaining bolt for either maintenance or replacement of a flute.
