Base cutting apparatus for sugar cane harvesters

摘要

A sugar cane harvester has a pair of contrarotatable base cutters with projecting blades to sever cane sticks from their roots. The base cutters are constructed to minimize the quantity of earth fed into the harvester with the crop. A large free area is provided between successive blades for earth and rocks to drop out, but each blade has a long exposed cutting edge to prevent cane sticks entering said area without being cut. The blades are mounted on a support member having a flat profile to minimize the paddling action of the base cutters on earth and rocks.
