ABSTRACT:
A crop conditioner has a frame adapted to travel along the ground, an upstream pair of vertically spaced ribbed rollers to which is supplied a stream of crop to be conditioned, and a downstream pair of ribbed rollers downstream of the upstream pair. A drive counterrotates the upstream rollers at a predetermined speed and thereby takes in the crop stream, conditions it, and puts it out toward the downstream rollers. A drive also counterrotates the downstream rollers at a predetermined speed which is different from the predetermined speed of the upstream rollers and thereby takes in the crop stream from the upstream pair, conditions it, and outputs it, normally laying it back on the ground.
