Hello. For 5 years I had a one-acre place in Dallas, TX, and mowed nearly year-round. 2-3 times a week for about 8 months, and less-frequently in the winter, often just mulching leaves. I did this with a 2007 Toro 20057 SR4 super recycler. It has the Personal Pace propulsion. I began having trouble with the transmission after about 3 years. I'd take it apart, looked ok, replace the belt, and it would go again for awhile. Finally quit working at all after 4 years. I took it to the Toro dealer, they said the gears had worn down past the point where they'd work, and this wasn't covered by warranty because it was excessive wear, even though it was in the 5-year warranty period. I guess mowing an acre puts a lot more time on the mower than a 1/4 acre lot. So I paid $100 for a replacement drive system on E-Bay and put it in. Now I have a 1/3 acre place. Much less mowing, but a lot more back-and-forth where I just push forward a couple feet and pull back a couple feet. I find the Personal Pace doesn't work so well for that, the rear wheels are often partly locked up when I pull back. Need to coast forward a bit to get them to spin freely, I found. I didn't experience this on the acre lot with the original drive system. Partly because of the way I used it, and maybe I didn't get the new drive system adjusted properly. The B&S engine also started giving me trouble. Wouldn't maintain power. There were no adjustments to the carburetor, so I put in a new one for $36 and that fixed that. So I'm back in business with my 5 year old heavily used Toro, though the Personal Pace doesn't seem well-suited to the smaller yard. I came into a little bit of money recently, enough I could splurge and drop $1,000 or so on a mower. I know that's totally unnecessary, but I really appreciate and enjoy using a nice piece of machinery, and something like that would make me happy if it worked well and was reliable. First decision is self-propelled or not? With all the push/pull and maneuvering I do in this smaller yard, maybe a fancy mower with ball bearing wheels would be easy enough to move around. Or maybe a different type of self-propelled that backs up easily. What's I've got my eye on after lots of Googling is the Toro 22197. Heavy duty recycler with a big Kawasaki engine and a different sort of self-propelled. I've read lots of good things about this mower on this and other sites. With my long-winded explanation of my particular situation, what do you think about that choice? Is that going to feel like a well-built pro-level machine, not wear out on me in 4 years, and be nice and smooth doing push/pull a lot with this kind of drive system? Or the 22155 which has the Honda 190 and is push? Thanks for any advice. Do you think there will be something new and gee-whizzy in 2013 that I should wait for? Might a get a little money off now that fall is here?
