So my 30 year old troybuilt rear tine blew a connecting rod.... which commercial rototiller should I buy? Seems to me the 4 top choices are:BCS;Troybuilt;Honda and Huskavarna. I am leaning toward a BCS but they are pricey; 5200.00 for the biggest. Is this a good machine? Anyone own / use a BCS? They use gears instead of belts and say they have a faster tine rotatation speed than the competitors. Any thoughts / help would be great. Thanks guys. Jim.
