I got a slip clutch on mine and on my old sovema tiller i had one too. I like the slip clutch over the sheer bolt as then a guy doesnt have to worry about much. Once you slip the clutch a few times(and you dont have to service them, i just do it for preventative maintenace), you can take them apart and clean the clutches and your good to go. You guys are lucky down there, Agri supply is awsome and the price is un matched. The slip clutch style that is like an adapter there is only 90 bucks, i looked at one the other day and it was over 200 here.
