If I'm almost done I'll kick it into high gear and try to finish if it starts raining as long as no lightning or downpour. I have no problem cutting grass in the morning when it's still wet from dew because I'm on 2 acres out in the country. My nearly entry level Cub Cadet doesn't care either way and neither do I. Beats waiting until the heat of the day. If I lived in town and had a small yard that could be knocked out fast with a push mower things would be different.
