Looks like it's way past due to show that old field cultivator some love and start replacing bushings in those shanks. Much as they were wiggling around, be missing lots of weeds and grass. As grown up as that first field was, I'm surprised it wasn't plugging up and looking like a giant hay rake.....
It was plugging up a little bit, but it was too wet to get in the feild with our disc. This spring we are going to replace all of the shanks as they are very worn, and make a rolling basket for it.
