Big Green - I have seen numerous posts all over the "Ag" corner of the net referring to horsepower shortages in the STS's, foreign objects causing many thousands of dollars worth of damage to the rotor (One poster said his rotor exploded from a foreign object causing $15,000 worth of damage to the rotor, cage, and grain bin!),and recently a few posts about uneven distribution of bean residue from the chopper. These, to me at least, are very compelling reasons to question the purchase of an STS at this point in time. Now, having said that, readers on this board have read that a few mods to the Gleaner rotor can result in less than 1% crop loss and they want to know how to do it. Perhaps that is the reason for the questions around here that you have noticed. One more big reason to choose the Gleaner is all the help you can receive free of charge right here on Gleaner Talk. And look at it this way - if we can't help you, the entertainment value is stupendous! Good luck!
