I have recently taken on a commercial account on a business that was just built. It has a 45 degree pitch to the hill in front and was poorly graded by the contractor. It has been sodded and has sprinklers throughout. The sod won't stay in place when you walk on it, let alone try to mow it with a walk behind. I spoke with the manager today to see if I could convince him to maybe plant shrubs, trees or ground cover on the hill. He told me he was watering it for an hour a day and that should solve the problem. So now I have a rough grade, a steep slope and do more damage every time I try to cut it. Help!!!!!
