Abstract
Four (4) methods to reduce stalk shear in a corn head row unit utilize a non-variable or dependent drive system. The four methods described include altering the gearbox ratio, increasing the lengths of the fluted portion of the stalk roll, increasing stalk roll diameter or reducing the size of the gathering chain drive sprocket. A method for reducing the size of the gathering chain drive sprocket includes the steps of providing a kit with a kit gathering chain drive sprocket of reduced size and replacing the gathering chain drive sprocket with the kit gathering chain drive sprocket.
