Abstract
Abstract The present disclosure is directed to a device for topping sugar cane stalks while harvesting same which provides a flat walled structure which rotates with the topping cutter to provide a flat positive knocking surface to engage the cut top and knock it to either the right or left side of the harvester. The topper drive is reversible so that cut cane tops may be knocked to either the left or right side of the harvester.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
For use with a sugar cane harvester having a prime mover and drive system for actuating rotary cane earth severing cutters and toppers, a sugar cane topping cutter and selective cut top director comprising: a. a substantially flat rotary circular cutter; b. a single vertical flat walled box-like structure upstanding from said circular cutter and secured thereto; and c. reversible drive means adapted to be connected to the drive system and to selectively drive said cutter and flat walled box-like structure clockwise and counter clockwise for knocking cut tops to either the right or left side of the harvester away from the harvester side adjacent the rows of cane to be cut.
Claim 2
Dependent Claim
