You NEED to get those units as soon as possible. I know the situation stinks but those weeds ain't getting any smaller. You shouldn't be cultivating big weeds with a Lilliston anyway. All you will do is roll over them and within a few days they will stand back up. The cultivator will only do a good job if you get in EARLY enough. So I think you have to bite the bullet and either get cultivating with 3 rows or go and pick the rest of the units up somehow. Sorry If I sound harsh, but thats reality.

And shame on you ( fellow poster ) who ever you are.
