Well we have a JD 7000 6 row corn planter that we use.  We only farm 120 acres so we hire a custom harvester and have been family friends for a long time.  they just upgraded their combine and now have an 8 row head.  Any advice on how i can make this work without to many smashed rows especially doing the end rows and opening a field up? (buying an 8 row corn planter is not an option)
