I had a very similar problem last year. It was a skunk(s) that we're after grubs.
You're picture is what my lawn looked like when the digging started. In just a few days large areas were damaged. I trapped one skunk. If you rake up in the general area of the digging, you may find some white grubs.
PS While the digging was going on, there was no skunk scent at all & that made me think it might have Been raccoons. But, the critter in theHave-Heart-Trap sure wasn't a raccoon!
