    Abstract: A pneumatic raisin harvester for harvesting dried-on-the-vine raisins grown on a trellis system comprising a plurality of support stakes and a trellis wire interconnecting the stakes spaced apart from the vine trunk. The harvester has a support assembly attached to and transported by a tractor or other vehicle. A support arm extends outwardly from the tractor to support a harvesting head having a head enclosure configured to straddle the trellis wire and support stakes. A crop separating mechanism, such as a plurality of beater rods, disposed inside the head enclosure dislodges raisins from the vines. A raisin collecting system transports the raisins to a venturi inlet that is hydraulically connected to a hydraulically powered pneumatic conveying system comprising a blower that discharges pressurized air through one or more air tubes so as to deposit the raisins in one or more raisin bins on a bin trailer towed by the tractor.
