Abstract

A harvester includes a main frame supported on a ground surface for transport along the ground surface, an inlet for receiving a crop, and a separator for separating the crop into a first portion and a second portion. The separator includes a hood having an outlet, and a fan operable to generate an airflow through the outlet. The hood of the separator is movable relative to the main frame between a transport position and a harvest position. In the transport position, the hood is positioned at a first height above the ground surface. In the harvest position, the hood is positioned at a second height, greater than the first height, above the ground surface.
