I have about an acre lot that I recently purchased. The lot is about half wooded, with trees approximately 10' to 20' apart, and half is lawn that is to be mowed all the time. I plan to mow the lawn all of the time and to mulch around the tree areas every 3 times I mow. I have started to look at lawn tractors with 18" turning radius and I think that is going to be sufficient for my needs. Specifically, I have found a John Deere L111 (20 hp B&S ohv w/ 42" deck) for $1599 with a bag thrown in for free. I have used walk behind Lesco's and that sort of mower before when I mowed commercially and know they are good mowers, but I don't think I need that sort of thing for one yard. Let me know if you have any suggestions or comments.
