Use the shovel to dig into any high spots in your yard to remove the dirt and level the ground. Load excess dirt and grass into a wheelbarrow. If you have low spots in your lawn, you can use this dirt to raise these spots.
Remove any small rocks with the shovel. If you encounter large boulders that you can't lift with the shovel, slip a pry bar under one side of the rock and push on the bar until you can lift the rock. Position your shovel under the rock and lift it out, using others to help you, if possible.
Rake the recently excavated area with a heavy rake to create a smooth transition between this area and the lawn around it. The goal is to have a seamless transition between your existing lawn and the newly created smooth areas.
Plant grass seed in the newly leveled area. If the sod you removed during the excavation process is still adequately intact, you can push it into place so you don't have to wait for grass to grow.
