ABSTRACT:
A hay conditioning roll is provided with a plurality of equally circumferentially spaced ribs extending across the axial length of the roll, the ribs having a slope relative to the axis of the roll reversing from positive to negative at least once. The configuration of the ribs such that the absolute value of the slope gradually decreases to zero, passes therethrough, and gradually increases upon approaching and passing the point of reversal, the rib configuration preferably being sinusoidal. A roll is adapted to run on a parallelly disposed roll of similar configuration reversed end for end, the ribs of one roll intermeshing with the grooves of the adjacent roll.
