<p>A harvester for brassicas, the harvester being movable along a plant row and comprising an endless conveyor (20) orientated in the direction of the plant row, the conveyor being of generally tubular form defined by opposed rows of arcuate conveyor fingers (22,24) movable from an open condition in which free ends of the opposed fingers are spaced so as to define a generally tubular configuration which is open at one side to a closed condition in which the free ends of the opposed fingers are adjacent to define a generally closed tubular configuration, the conveyor (20) having an upper run and a lower run, the conveyor (20) being configured at its forward end portion so that the fingers (22,24) are in their open condition during transition from the upper run to the lower run and move downwardly onto a plant to be harvested so as to move foliage away from the plant head and to allow the plant head to enter the interior of the conveyor (20) through the open side, with the fingers (22,24) then moving to a closed condition to thereby capture the plant head with the interior of the conveyor (20), the harvester further comprising means (12) for cutting the plant stem whereby the plant head severed from the remainder of the plant can be carried by the conveyor (20) for discharge from the conveyor when the fingers by which the head has been retained are returned to their open condition.</p> |
