We ran them last year on a 30' 1020 in beans. By the time we cut the first 20 acres we had already broken two. By the time we had finished 1250ac the only ones left were the outside one on each side. With a full set on the auger would throw beans and stems everywhere and the auger would wrap up. With just one on each side seemed to work the best, helped the outside from bunching so bad. If I was to do it over again I'd just put the two outside ones on. Better yet, as another posted, go to the full finger auger.
