RAH , That is a LOT of work for sure. That rig was a homemade rig but worked pretty well. I helped one day when one of his guys didnt show up. Kinda like a potato planter. It cut the sod opened it up throw a wip in it pulled it down closed it up and sprayed about a 2' swath of roundup at the end. Then they told be to drive my tractor over the rows. I was impressed with the survival rates all and all.
