  • Patent number: 3962072
    Abstract: A harvester pick-up particularly for retrieving fallen nuts and fruits, such as almonds, oranges and the like, from the ground includes a mobile frame preferably self-propelled or tractor drawn and having a primary rotary brush generally in contact with the ground and mounted on the frame for rotation transversely at the leading end thereof. Also disposed on the frame is a power driven secondary brush parallel to and behind the primary brush and arranged so that the tines on the brushes interdigitate or interrelate and operate in such a direction that they pick up materials from the ground between them and toss the picked-up materials onto a reflecting panel from which the materials are deposited onto a primary conveyor belt leading rearwardly. A stream of air is impelled to flow along the primary conveyor and assists in lifting lighter waste materials therefrom.
