I have been mowing Monday-Thurs. leaving Friday for rain delay and odd jobs. If it rains early in the week I usually can catch-up all but a couple by Friday. I'd really have to hustle to get 35-38 yards cut in three days. For the size yards I have the equipment to do it, although I think a 25" Y-bravo will probably make it so I can easily do it. (It would knock off just enough time.)
If I could do this I would have four days for other things. I have tons of landscaping I'd like to do at my own home.
Did you check out White gardens work? I can wait to see your work also. I am just learning landscaping.
