I have a client that has a very healthy lawn. I have been caring for this lawn for the last three years. Front and sides are very smooth no ruts. The back lawn has three 120 foot runs of irrigation lines that did not get back filled correctly. The home owner has asked me to correct these ruts. My question is how do I go about correcting this? 1. Do I rent a rear tine tiller and till up the ruts, rake up grass, fill ruts and overseed? 2. Sod cutter (but do not know how I would get the sod out as it is small rut in width, but fairly deep (2 - 3 inches) Any suggestions would be greatly appreciated.
