I have been mowing about 15-20 residential lawns each summer with a push mower for about 5 years now and was thinking about upgrading to a zero turn or a walk behind mower. I was wondering if anyone had any suggestions of a good mower that isn't too expensive. I also wanted a small deck size so I can make it through fences. Possibly something in the $2000-$5000range. Also, I plan to add more lawns over the next few years. Thank in advance for the help.
