I just moved back to Ohio and bought a house south of Dayton.  It has a 0.6 acre yard.  I thought that I was going to be able to mow it with my self-propelled push mower, but my eyes were bigger than what my right knee can handle after 4 surgeries.  I'm looking for advice for a riding mower.  Right now I'm comparing the John Deere D105 and the Cub Cadet XT1, but I'm open to other options.  I don't think that I need anything bigger than a 42" width and I shouldn't need more than 20 HP.  I also read that Cub Cadet completely redesigned its riding mower in 2015 after years of bad reviews.  If anyone has any advice I would greatly appreciate it.
