Good luck getting any useful information from some of these guys. My place is on about a half acre (about 22,000 square feet) and I mow, trim, edge and blow, by myself, with a homeowner 21" since the place is too rocky for a good mower and has too many trees for a bigger mower. It takes me about 1.5-2 hours. So, not including drive time and setup/teardown, I would expect that you could do 3 or 4 per hour. You're only talking about a handful of acres. I'd feel comfortable trying to get that done in two fairly easy days, if they are close together. Hell, if it takes you 20 minutes to drive to each, 10 minutes to unload, 10 minutes to load and 20 minutes to mow, trim, edge and blow, you can still get it done in three days and contrary to what others might say, it will be a fairly easy 3 days, since you will be resting 40 minutes for every 20 you work.
