Rated 5 out of 5 by from More Power! This was a replacement for a 20 year old machine with 17 hp and non-hydrostatic manual transmission. I have a hilly property and the automatic transmission along with the greater horsepower has reduced my mowing time by about 25%! The only downside to the the machine is that the profile is a little higher and the machine feels a little less stable on steep inclines. Still, the trade off is worth it! [Regarding the "Reliability" below, I haven't owned it long enough to really rate it so I just checked "Excellent" to complete the form.
