Mowing lawn in the evening/night. Big deal?

[Jonathan Perez]

Is it a big deal if I cut the grass when I get off work in the evening? I was wondering if it would be annoying to the tenants or the neighbors to hear the lawn mower in the evening. It would be about 7:00-7:30pm when I start cutting. I was going to wait until Tuesday. I'll be off and could cut around noontime, but the grass is fairly high and I want to show the tenants that I'm on my job.
