i have a new yard that i'm going to sod. the neighbors on each side have existing grass. instead of using a shovel or skidsteer, how can i create the little step and straight line so that when i lay my sod, the new sod is at the same elevation as the neighbors grass. i dont want to just lay the sod over the dirt and existing grass, since there will be a little step. the edge of the sod will be exposed. will a sod cutter be the best thing to use? just make a straight pass along the property line and then the new sod should sit flush with the old grass, right?
