Jeez, do it at lunchtime. Everyone is stuck in their houses, some people will just want a lie-in; others may experiencing insomnia from the anxiety of all this and the last thing they need is your matinal mowing.
But then I'm a sleep-deprived, noise-sensitive night-owl and would ban all gardening and DIY noise during lock-down. It is enforcing torture on neighbours who are powerless to get away from it.
