I'm looking to get into some light commercial lawn mowing in my neighborhood. Needless to say, I will just be using a JD riding mower with a 50" deck to pull a dump cart that will hold a walk behind, weedeater, gas can, etc. I'll be able to ride on my mower to 300+ houses quicker than if I were to go through the hassle of loading/unloading on a trailer pulled by a truck or something. The types of lawns I'd mow will vary, but most will be 1/4 to 1/2 acre in size. The walk-behind will be primarily used in lawns with a fence that doesn't allow my 50" deck through. I'm hoping to get around a 32" deck or so for a walk-behind as reasonably priced as possible. I don't have thousands to spend. Any suggestions? I'd be interested in web sites good for used equipment, particular models, anything you're willing to share. Thank you.
