I have just got a quote for 1 inch and 2 inch dutch openers. I want one coulter for drilling everything from cereals to beans. How common is it for the 1 inch to block on beans as that's my main concern. The beans will mainy be home saved and cleaned Tundra. I have no problem drilling at 8-10k if needs be as we don't have a huge acreage but grow some beans every year after grass.
