Anyone ever used one of these or something similar? It's a Kinze 3005 set up with interplant rows for planting 15'' rows. Can be converted to 30'' rows in minutes. Also available with liquid or dry fertilizer attachment. I'm thinking od buying one to replace my 2006 6 row John Deere 1750. Mostly because it will allow me to plant corn the same as ever but soybeans will go in twice as fast as I'm accustomed to because I like soybeans in 15'' rows. Other reasons as well. John Deere no longer makes a model like this in a drawn planter but does offer one in a mounted version. I'm looking at that, too.
