I'm starting out in 2007, I have been on lawnsite for about 2yrs. I have worked for the largest lawn service in my area. It will be tight money wise so buying a mower, I will have to buy a residental push mower for the first year. I the average size yard I will be going for will be 20,000-25,000 sq. ft. Can you all direct me a to good push mower, perferably self propelled, and give me and ideal on how much I can get done with a small mower on yards size list above or smaller. I will need to make $500 weekly to be able to make it on my own. I this possible. Thanks in advanced. I have been pushing yards for 4 yrs with a 20" murray 8 accounts.
