Abstract
A beater for an agricultural combine comprises an open rotor frame mounted on a drive shaft. The open frame defines a cylindrical periphery to which are mounted transversely extending mounting plates. Adjacent mounting plates define mounting channels. Replaceable crop-engaging blades are mounted in the mounting channels. The mounting plates are provided with a first upturned portion and a second upturned portion. Each replaceable blade is provided with a crop engaging portion and an integral mounting portion. The crop engaging portion of the replaceable blades is provided with first and second mounting lips. The first and second mounting lips respectively engage first and second edges on the first and second upturned portions to prevent rotation of the replaceable blade. The crop engaging portion of the replaceable blade extends outwardly from the mounting channel to engage the crop. Open gaps in the mounting channel are formed between adjacent replaceable blades.
