Abstract: A grape harvesting machine comprising a mobile carriage having a picking head operatively connected thereto. The picking head including a main frame connected to said carriage. A plurality of picking rods which are movable back and forth are arranged in banks disposed on opposite sides of the main frame. The main frame is mounted so as to be suspended from the carriage and freely pivotable relative thereto. The banks of picking rods can adopt one operating mode in which the banks of picking rods are freely pivotable about the pivot axes so that, in use, the banks can change position as the harvester moves along the rows of vines. The banks of picking rods can adopt a further operating mode in which they can be secured in selected operating positions including a generally vertical position or selected inclined positions.

Abstract: A picking head suitable for use with a harvester, which includes a mobile carriage. The picking head comprises a support frame having a support frame axis which in the operative position extends generally in the same direction as the normal line of travel of the harvester and link means operatively connected to the mobile carriage of harvester when in the operative position. The link permits lateral vibrational movement of the support frame with respect to the direction of said support frame axis. The support frame is adapted to have secured thereto harvesting elements which, in the operative position are secured to the support frame so that the lateral vibrational movement of the support frame causes lateral vibrational movement of the harvesting elements.

Abstract: A bucket conveyor system 13 for a harvesting machine which can move along a row of plants. The bucket conveyor system has a pair of parallel endless roller chains 18 guided for movement along a generally rectangular path 17, and open-topped buckets 19 connected to the chains 18 at equally spaced intervals along the chains. The buckets each have a rear lip 36 extending over and beyond the front wall 32 of the next rearward bucket 19 to prevent gaps through which harvested fruit or juice can fall. The sole connection of the buckets 19 to the chains 18 is by a single shaft 44 projecting outward from the upper end of each side wall 31 of the buckets. As a bucket 19 is elevated, a fixed vertical bucket guide 27c engages a substantially vertical front wall 32 of the bucket to keep the bucket erect, with the engagement of the bucket guide 27c with the bucket wall 32 being at a substantial distance from the pivot connections 44 of the bucket to the chains to minimize stress in the bucket.
