Most of us cringe at the idea of using a 21", but... My wife is wanting to work with me and she likes the idea of running a 21". This works out pretty well since I'm running into calls from people who have a small yard and a fence that I cant get through with a 48" wb - so all of this might work out very well with the wife and a 21" and me doing the trim/edge/blow. I'm looking at the Toro Personal Pace line, probably the homeowner version that I'll add steel wheels to fairly quick. (the 3-in-1 setup). I owned one several years ago, it had the cast alum. deck and it worked pretty well. I hated that it had no side discharge and the drive unit started growling and grinding requiring replacement (was that just a fluke?). Obviously I'm willing to look at other options. Do you have any other recommendations?
