Abstract
This blueberry harvesting machine is a side-by-side attachment to the standard farm tractor, secured to the tractor by the usual 3-point hitch. An outer wheel on the attachment supports much of the weight of the machine. A simplified beating mechanism knocks the berries loose from the bushes to fall on a collection system that extends ahead of the beaters and the frontal portion of the machine to receive berries knocked loose by the approach of the machine.
