ABSTRACT:
A row crop attachment for forage harvesters has a plurality of row crop divider units arranged side-by-side on a base frame to define a plurality of crop conveying paths through which gathering chains pass for conveying crop material through the crop conveying paths. A pair of rotary knives with cooperating cutting edges are disposed adjacent an entrance of each crop conveying path for cutting off crop material before it is conveyed through the crop conveying path by the gathering chains. A mounting arrangement for each pair of rotary knives includes one knife of each pair of rotary knives fastened to a hub shaft which has a splined connection with a sleeve that is rotatably supported on the base frame. A spring urges the hub shaft in a direction to urge the cutting edge of the one knife into contact with the cutting edge of the other knife of each pair of rotary knives.
