cbellfarms - 5/6/2016 20:31 Air pocket is bad because of poor seed/soil contact resulting in late emergers. Those 3-4k have cost me several bushels per acre. But that is no more. Half the rows are new yetter spike wheels that look similar to copperhead furrow cruisers and the other half are the regular yetter cast spike wheels. Only ran a round in before dark but they fixed my problem.
