Base Cutter Blade

摘要

An improved base cutter blade suited for use in a sugar cane harvester. The preferred improved blade has a generally elongated flat body with opposing longitudinal edges. A removable, replaceable knife is also provided. The knife is made to releasably engage the leading edge of the body. Grooves are preferably centrally positioned in both edges of the body. In the preferred configuration, the knife dovetails with the portion of the groove corresponding to the leading edge of the body. Thus, the knife will perform most of the cutting work and bear the brunt of the wear suffered by the blade. When the knife becomes dull, only the knife need be replaced, which can be done quickly. This will save a significant amount of time during harvest operations. It will also reduce the amount of material that is consumed in the form of worn out blades.
