Please don't run them at night to protect animals like hedgehogs and others that are active at night.

Even better is to turn most of your lawn into natural landscape, leaving just the part you want to use for recreation as mowed.

This is highly dependent on where you live and what kind of creatures and insects you will be hosting.

I’m a big fan of natural landscaping, but just letting your grass over grow is not that.

It's a nice thought but the reality is that you'll be killing animals no matter what. I have a 48" riding mower and live in a rural area. At first I was really worried about all the field mice, voles, frogs, etc., that I saw running away from the mower. After a while, I realized that no matter how hard I tried, a certain number of them were just going to die. I tend to let my lawn grow fairly tall before cutting, and it's a mix of grasses, clovers, wildflowers and other plants that just grow naturally around here. The downside is that a lot of small animals live in it. I only remember running over one bunny so far, but who knows how many I might not have seen.

At least it's not fawns. Baby deer seem to be a magnet for combines harvesting corn.

Also to protect all those, animals and humans alike, who would like to enjoy a silent night.

I'm assuming (perhaps unreasonably?) that given the suggestion you could run it at night, that it's silent, or near silent?

If that's not the case, GP must be a madman.

I mean how fast do these mowers mow? I seriously doubt it's fast enough to run over an animal

I think the concern is animals that hide or sit still when threatened more so than it chasing down a rabbit :p Also, eventually animals would get used to the noise until they get hurt.
