I have been looking at the Yetter Flex 71 one-row planter. It appears that you are better off buying your own 4-inch toolbar for your three-point hitch separately. If you buy their hitch assembly plus the tool bar from Yetter you are going to be well over $400. I believe you can purchase the toolbar for much less money that will attach to your three-point hitch. I also found out that the new Yetter Flex 71 planter does not come with any seed plates. You have to purchase the seed plates separately. You purchase those plates from a company called: Lincoln Agricultural Products. The seed plates are plastic and run about $10.50 for each plate. Do you all know where to look for a 4-inch toolbar that will attach to a three-point hitch and other source for the seed plates?
