I am trying to become as professional as I can at lawn mowing- I bought professional equipment and am going to be insured this summer but there is one thing- how do you become licsenced in lawn care? do you have to go to the city and take a test? If someone could fill me in on what a person has to do it would be appreciated. And also, I am buying a Wright Stander in a month or so and was wondering what you guys thought of them. Which engine would you choose on a 52 inch deck- 17kawa, b/s, kohler, or 23kawa? Thanks.
