Abstract
A pickup reel for a harvester which includes stops for preventing over-rotation of bat tubes. The pickup reel includes a main shaft and a plurality of reel arms which extend from the main shaft. A bat tube is engaged with an end of each of the reel arms. More specifically, the pickup reel includes a plurality of bat tubes, all of which are parallel to each other and parallel to the main shaft of the pickup reel. Each bat tube carries a plurality of tines and is supported by a plurality of reel arms which extend from the main shaft. Associated with each bat tube are a plurality of stops for defining the range of allowable rotation of the respective bat tube. By restricting the amount the bat tubes can rotate, crop does not tend to get wrapped around the bat tubes during operation of the harvester.
