A pair of superposed parallel crop conditioner rolls, one journaled in a frame on a fixed axis, the other mounted for generally upward and downward movements toward and away from the one roll. Springs yieldingly urge the moveable roll towards the fixedly positioned roll, and stop elements limit movement of the moveable roll toward the fixedly positioned roll. Adjustment mechanism positions the moveable roll generally forwardly or rearwardly relative to a position vertically spaced from the axis of the fixedly positioned roll.
