I'm considering ZTRs. I don't have a ton of grass to mow, just over 1 acre, slightly sloping, with one ditch at the rear to handle. Lots of trees in the rear. I've seen lots of posts, and based on what I see around here I can easily get Exmark and Hustler (along with Scag although the local guy says getting parts is difficult). The Exmark carries both the Kawasaki and the Kohler, with the Hustler running a Honda. I've seen some posts saying the larger Honda engines weren't great, so I'm asking for opinions. Which engine would you choose? Also, I'm having trouble figuring out the Exmark Lazer Z vs Lazer Z HP, and then there is the Hustler Fastrak vs the super Z. I really didn't want a huge deck, just something that will do a good job on my lawn, require little maintenance, is easy to adjust deck height (I have two types of grass), can handle slopes, and will last forever. Opinions, besides getting demos of each?
