You fellers must have tougher beans than we do, or your winters are milder and don't break down the bean straw as much. We have never used a chopper and simply spread the bean straw - and we always notill our corn into the bean stubble the following year. Never had even the slightest problem even when the beans were green and the stems didn't break up much in the rotor. Have even planted when the bean residue was damp and tough and no problems. Seems by spring, our bean residue is like brittle twigs that snap easily. I don't foresee ever needing a chopper with our conditions - thankfully. I think they are just something else that needs maintanance. Heck, now that I think of it, we just spread the bean straw when we used conventionals too - and the straw came through nearly intact and didn't have trouble. Tom langan
