Hello, I am wondering what the best way is to prep a lawn for sod. I have three jobs lined up where the lawn has many weeds and bare patches and the customers want it re-soded. I guess my options are roto-tiller, bobcat, or sod cutter. I dont like the idea of a roto tiller... seems a little overkill, bobcat wont fit, unless i rent a walk behind one, but ive never used it and not sure how well they work. and i have never used a sod cutter. just looking for opinions and any advice you can give. thanks.
