Abstract
A sugarcane harvester configured to cut sugarcane into a sugarcane mat having crop debris and billets. The harvester includes an extractor configured to receive the sugarcane mat at an inlet and to discharge crop debris from the sugarcane mat at an outlet. An extractor located between the inlet and the outlet includes an extractor fan having fan blades and a vane assembly including a plurality of guide vanes, wherein the angle of the guide vanes is adjustable. A selector includes a manual position to enable adjustment of a rotational speed of the fan blades and an automatic position which automatically adjusts the rotational speed of the fan blades. A controller identifies the position of the selector, and in response to the position of the selector adjusts the angle of the guide vanes to optimize fan performance for cleaning and fuel savings.
