Abstract
A harvesting head for a collection machine that harvests material. The head includes conveyor belts to transport material towards the collection machine, and blower heads to help prevent material from falling off the conveyor belts. The conveyor belts can include a feed belt that feeds material towards the collection machine, and a side belt that carries material towards the feed belt. Blower heads can blow across the side belt and towards the center of the feed belt. Blower heads can be located below the side belt. Blower heads can be located near the front of the feed belt and blow towards the collection machine. A feed drum can move material towards the collection machine, and blower heads can blow across the feed drum and towards the feed belt or collection machine. Blower heads can be movable, or have adjustable flow rate, velocity, direction or spread.
