So I have been doing some research and looking at some different planters, mostly online and used not new ones. Anyway I am looking to purchase a planter possibly this year if not definitely next. I am going to be adding some acres in the next year to my "hobby farm" and I stress that is what it is just a hobby right now, I have a full time job and other comment's also. I just like to use the tractors and equipment we have and have restored. So I am looking to my upgrade my planting operation, but I am not sure what to look for exactly. I just have an old 2 row plate planter that I use now to plant sweet corn. What I am looking for is a 4 row finger style planter with dry fertlizer and set to 30" rows to plant field corn. I have been looking at JD 7000 series planters. Them seem to be very popular and parts avaiablity seems to be good. I see a few for sale but there are on 36" rows, like I said I want to go for 30" rows because I will probably have to hire a local guy to combine my first few years of harvest and most everyone around here uses 30" rows. So now I guess my questions are: 1- If I find a good planter that I can afford such as a JD-7000 and it is set to 36" spacing how hard would it be to narrow it down to 30" spacing? 2- I will be doing conventional till, If I found a no till or conservation planter can I use it when doing conventional tillage? Or is there alot of things that would have to be changed over? I guess that's it for now, thanks in advance.
