Abstract: The simultaneous processing of multiple rows of plants, especially trellised rows. Apparatus is provided to process two adjacent rows, using a conventional tractor with narrow gauge front wheels, with rear wheels on opposite sides of the two rows with a larger gauge.

Abstract: A conventional harvest bin carrying grapes is transported to a winery onboard a flatbed trailer and is emptied by tipping the bin on end so that the grapes tumble over the side of the trailer into a conveyor. The modification of the present invention permits the bins to be emptied into a dump truck at the vineyard by a forklift equipped with a rotator attachment. This permits the bins to remain at the vineyard where they can immediately be reused, thereby greatly increasing the efficiency with which the bins are used. The modification consists of permanently adding a receiver tube to the bin so that an elongated trunnion beam can be removably inserted through the receiver tube to a position at which end portions of the trunnion beam protrude beyond the ends of the receiver tube to serve as trunnions for use in lifting and rotating the harvest bin. The elongated trunnion beam can readily be removed when the bin is to be used in the conventional manner.
