I am just someone that mows dos lawns all day, with a 21"murray push mower, its five years old but rns great. I just use siccors to put and round the trim. Maybe some day will git engouh money to buy a bigger mower. i have six lawns now that are an acre and get thirty bucks apiece. takes bout four hours non stop. but i figure im getin bout 7 or 8 bucks to the hour most the time,, beats doin stuff i get caught for. What do you guys think my next step shoulds be? k. Later now.
