  • Patent number: 4147017
    Abstract: A tomato harvester supported on a draft propelled chassis and having a pair of header conveyors to simultaneously harvest two adjacent crop rows. The chassis is supported on wheels so spaced relative to one another that they may travel between the crop rows and an adjustable draft tongue enables a draft vehicle for the harvester to be positioned in aligned spanning relationship to a crop row ahead of the harvester. During harvesting, the crop, including the vines therefor, is lifted by the harvester and conveyed longitudinally over its length. A shaker conveyor having means to continuously vary the ratio of conveyor speed to oscillation rate subjects harvested vines to shaking to break attached tomatoes away from the vines. A separator is provided to separate loose tomatoes and dirt clods from the vines in advance of the shaker conveyor. Collecting conveyors collect loose tomatoes and dirt clods and preliminarily separate dirt clods from the tomatoes.
