Ummmm, well I can not cross rows. We specifically have to follow the same tracks for all field work, planting, spraying, harvesting. So that cross cutting is not an option. I did not consider the knocking down the row with the header. I am doing that sometimes now with narrow guess rows and tight turns. It kindo drives me nuts to do that. Thanks for the info!!!! SO 15" may not be a good option for us to look at. Plus if the gain is only a couple bushels an acre, then the pay off on the planter is going to take some time. We could use our CrustBuster drill and plug off every other hole, but it really is not accurate enough to do corn, and we have had a lot of questions about that in this area, of 20 and 15" corn. But then the cost of one of those very narrow row heads scares me to death! They are more than our combine was!!!!
