What size is your average lawn? As I read all the posts I see how some people do more lawns in one day ( 40 to 100 ). I'm not a young man anymore but I could never have done that many lawns in a day in my area. I know that everyone talks about a tight route as well. When I get to the 1st lawn in the morning they are all within 5 miles of each other and the most I have ever done in one day is 7 or 8 lawns in 8 or 10 hours, and that is busting. I am a one man operation so that is slower than more people but with another helper maybe 14 or 15 but 40 never. I do use a 60in Z and a 52in walk behind for the hills and hard areas. The average of all my lawns the size is 2.5 acres. What about yours?
