these machines usually had a spike cylinder when set up for dry beans. very little cracking, and no rope making like a rotary would do in wet stemmed or dirty beans. we still use a jd 105 and 95 for specialty dry beans as they are very gentle when equipped with a bucket type clean grain elevator and a belt out the side of the grain tank. i have looked back several times in the grain tank and stared at a live and fully intact snake! not a rotary made that would do that!
