At What Time in the Morning Can You Start Up Your Lawn Mower Without Your Neighbors Getting Mad? [POLL]

While I was surfing around on Facebook today, I saw a buddy of mine pose a question that I have wondered for years. So, I figured I'd take it to you guys to see what you thought. What is the appropriate time in the morning to start up your lawn mower without your neighbors getting pissed off at you?

We've all had those neighbors that were loud well in to the wee hours of the morning and also those who woke earlier than the roosters and started making noise.

However, we all have our own limits.
