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.
Some would say the mower is causing problems for the tree . . .
