Got new to us DR 24 in shop and are looking at closing wheel options. We are on heavy Clay soil ridges and cover crops in near future what are you guys using. We are looking at curve tine but not sure so we maid up a wheel not sure if closing disc bearing and hub are strong enough. Any new technology coming out for closing systems. The gangs come from a lillistone rolling cultivatore. The gangs are 25 bucks from ASC. Bearings $15 from Deere and cups are reused from old closing discs.
