    Abstract: A sugar cane planter cart having a circular plate rotatably mounted in a vertical plane within the cart adjacent a load of sugar cane stalks.

The plate is carried on the end of a boom mounted on the cart having both horizontal and vertical movement to engage the exposed layer of stalks. The V-shaped elements can be detachably mounted and are generally made of mild steel with a buna-type rubber sheathing. The plate is rotated by a hydraulic motor means.
