Multi-rotor fan assembly for a cotton picker

A multi-rotor blower fan assembly for a cotton picker utilizes a plurality of separate fan enclosures each containing a fan for supplying an individual air flow to a picker unit of the picker, the fans being mounted on a common shaft for rotation therewith, with a unitary removable or openable cover or hood covering access openings of the fan enclosures. One or more of the fan assemblies can be mounted on the picker, for instance, on an existing platform on the picker chassis just rearward of the operator cab, in end-to-end relation, and rotatably driven using a common drive.
