I have several mature trees on our lot where the roots have come to the
surface and are sufficiently exposed to cause problems with the mower.

These trees are Maple and Ash.

Can anything be done to level the area under the trees.

I had though about placing sod between the roots but I have heard that is
not a good idea.

I had a friend who tried sod, followed by building a huge raised bed over
the roots. The roots still found their way to the surface. This is why
maples are to be avoided near civilization, or at least researched so you
know what you're getting into before planting one.
