Abstract
A harvesting header includes a cutter bed having a plurality of cutting elements arranged transverse to the header and a crop chopping and conditioning region having a crop chopping device and a crop conditioning device. The crop chopping device is configured to chop crop cut by the cutter bed into smaller lengths and the crop conditioning device is configured to crimp the crop to aid in drying. The first chopping roller has a tubular, cylindrically-shaped body and a plurality of parallel knife-mounting lugs extending radially outward along substantially the full length of the body. A plurality of chopping knives are attached to the knife-mounting lugs and arranged around the body, each chopping knife having a length that is shorter than the length of the knife-mounting lug to which it is attached such that each chopping knife covers only a portion of the lateral length of the first chopping roller.
