Abstract: A first and a second debris outlet on a fan housing having a single fan and single intake or suction opening on a nut harvester. The nut harvester being of the type having structure for picking nuts up from the ground and depositing the nuts onto a moving open conveyor chain to carry the nuts for deposit into a storage container. The harvester includes a debris removal system including the fan within the fan housing connected to intake ducting positioned to draw air through the open conveyor chain to draw debris from the nuts into the fan housing to be exhausted out onto the ground. The first and second debris outlets are positioned on opposite sides of the fan housing from one another, approximately 180 degrees apart, and positioned so that debris is discharged to the two oppositely disposed sides of the harvester.

Abstract: A wheel mounted harvester having a tow hitch at each end thereof for towing by a tractor, and to allow the harvester to simultaneously tow a harvest trailer. The harvester is used in orchards to pick-up nuts for deposit into the trailer towed by the nut harvester. Crop pick-up and cleaning mechanics on the harvester are powered by the power-take-off unit of the towing tractor. The harvester structure uses a pulley and vertically oriented drive belt arrangement at the front end of the harvester to transfer power from the power-take-off shaft to a support shaft of a suction fan and hydraulic fluid pump mounted thereto. The suction fan and housing therefor is mounted at the center front end of the harvester. Affixed to the fan housing and extending rearward therefrom is an elongated vacuum chamber leading centrally into a debris separation chamber.
