ABSTRACT:
An agricultural harvesting machine, such as a mower-conditioner or the like, includes a pair of meshing crop conditioner rolls between which harvested crop material is passed to accelerate the drying of the crop in the field. The rolls are of identical construction, each roll being made of a tubular metal core with a molded body of elastomeric material molded onto the core. Each roll has a plurality of generally radially extending lugs that are disclosed in axially extending rows, with the lugs on one roll meshing with and extending into the space between the lugs on the opposite roll, each lug having an arcuate outer surface coaxial with the roll axis so that the outer surfaces of the lugs conjunctively form an interrupted and generally cylindrical outer roll periphery. The outer surface of each lug is in the shape of a parallelogram having two opposite sides parallel to the roll axis and the other opposite sides canted relative to the roll axis. A recess is provided in the outer surfaces of each lug, the recess having a depth less than the height of the lug so that the bottom of the recess is outwardly of the space between the lugs, each recess being elongated and having opposite sides parallel and adjacent to the canted opposite sides of the lug.
