After extensive searching, it seems for what I want (lightweight, extremely high quality cut, and versatility in a 21" deck mower), the Lawn-Boy mowers are the premier choice. Question is, which one? I am looking at the Commercial line, self prop. unit, since it hardly weighs any more than the push mower, and seems to be a very simple unit. But, as far as finish quality, sometimes I've noticed that some of the residential mowers provide a higher quality cut than commercial mowers---at the expense of things falling apart much sooner, and more down time. I'll be replacing my Honda HRC216HXA with this mower, so I definitely want something that's of the highest quality finish, since I'm giving up one of the easiest to use mowers, in my opinion, that I've ever owned. Thank-you!
