This summer we laid sod in our backyard and we prepped/flattened the
sod underneath, but we were in a rush to try and finish some things up
before it started raining and I guess we walked on it too much before
it all settled because now the ground is fairly uneven and not as flat/
level as I would like.

Is there a way to level the ground under the grass now that it's
established?

Thanks,
Dave
