I am mowing about 20 lawns from 1/4 to 1 1/4 acre i want to get them done very fast but get a really good look some of these lots have fences and i am concerned about how big of a deck i could fit. I also have another lawn that is about 10 acres of mowing and it is mostly flat. If u could please suggest a mower that could fit both or one for each. also how much do u think i should charge for 10 acres mostly flat very wealthy part of town thanx.
