I live in the Midwest, and I would like to put in 500 asparagus roots next spring on my land. Problem is, under that waist-high grass there is a pretty great layer of sod. I CAN strip it back with a grubbing hoe, but the TIME that would take!!!!!! I cannot afford a tractor, and I lack welding supplies and such to build my own tools. I KNOW that they used to have sod cutters way back when, but I have never seen one and I doubt that I can get one. Any ideas? I have a tiller but I doubt it would do anything with the sod. I have a pickup, a riding lawn mower, and some hand tools.
