It is important to understand the significance of removing sod properly. Maybe you want to work on a garden and have to remove grass first, or you want to remove your grass and use a different type. The situations can differ, but removing sod can be incredibly difficult after grass has rooted. Sod cutters remove the grass and a thin layer of dirt underneath so that when you go to lay the new sod, it is flat and even with other parts of your lawn. If you don’t remove the thin layer of dirt underneath and once you go to plant the new sod, the sod will be laid on top of the dirt you didn’t remove. The new grass will not be level with pre-existing parts of your lawn.
