I see a few years ago there were some posts on retrofitting planters with the Jamison system to get rid of the wheel chains, clutch and other inherent issues with the stock planter. So those of you that did this a few years ago - any regrets/planting issues? Looks like a newer planter isnt in the works for a few years here and it would be nice to eliminate drive chain problems with all the notill we do.
