Unless, of course, the intent would be to try to eliminate the Bermuda
although unless your neighbors do the same thing at the same time its
futile...

Of course, even tilling won't kill the Bermuda tillers -- they'll just
get chopped up and regenerate. Only way to eliminate Bermuda entirely
is chemically over a long period of time (like a full year) or cart off
the infected topsoil. There is no practical way to eliminate all the
root system by tilling and even when spraying as soon as the existing
dies, there will be new coming from existing seed and that seed remains
viable for years.

It's a bugger to eliminate. Bindweed is easier I think...
