  • Patent number: 4266490
    Abstract: A sugar cane planter has a series of cane carrier elements which are moved through a supply of randomly oriented cane billets to select billets and deliver them to a soil furrow. The cane carrier elements move in a circular path and are maintained horizontal throughout said movement by attitude control means thereby providing sufficient time for reliable pick-up, doffing of excess billets, and billet alignment. A supply of billets to the selection mechanism is maintained from a trailed cane bin having a cane elevator. Fungicide is sprayed on the billets carried by the elevator.

  • Patent number: 4008557
    Abstract: Topping mechanism capable of selective delivery of cane tops to either side, for use in a two-way sugar cane harvester. The mechanism has a pair of contra-rotating in-running cutters which are always rotated in the same direction and which assist the discharge of cut tops for both directions of top delivery. The cutters have mounted on them hub members carrying projecting feed members which serve both to gather the cane tops and to discharge them. A top deflector is pivotally mounted between the cutters and according to its position deflects the tops selectively towards either of the cutters according to the desired direction of delivery.
