ABSTRACT:
The present invention relates to the mechanical harvesting of ground crops. More particularly, the invention provides an adjustment mechanism for altering the distance setting between centers of at least one pair of driven revolving pairs (such as helixes) on site as needed to suit changing conditions encountered during harvesting. The present invention achieves the above objects by providing an improved harvester attachment for row-planted ground crops, particularly vegetables, or the like the harvester comprising a framework supporting at least one revolvably driven helix, or the like, pairs, each helix having a front support bearing disposed slightly above ground level, the helix pairs extending at a slope upwards and rearwards, i.e. in a direction opposite to the direction of travel of said harvester.
