-23 Abstract Of The Disclosure A fan powered extractor system for a harvester, such as a sugarcane harvester, utilizes a 5 rotary extractor screen larger than an air flow path to the fan, that moves through the air flow path such that the air flows through the screen to collect airborne leaves and other crop residue thereon, and carries them from the air flow and deposits them on the ground beside 10 or behind the harvester or on another receiver without passing through the fan. The extractor screen can also pass through the exhaust air flow from the fan for blowing remaining collected residue therefrom, and the location of deposition of the leaves is optionally 15 selectable. |
