Thanks everyone for your input. I came very close to buying a Zero turn mower but the more I read about the handling on hills the more I decided it wasn't for me. I have a lot of 15-20 degree hills and a lot of rough area that I cut. I think front wheel steering and 4 good wheels on the ground would be a better fit for me. I have looked at so many tractors that I can't remember which is which. I found one that had a Tuff Torq k57 and thought it would have been more robust than the K46 all of the others had. Then I came across an article on CTV transmissions for garden tractors; that sold me. I like the idea that there are no pumps, motors or hydraulic oil to wear out. Time will tell If I made the right decision or not. I ordered a Husqvarna YTA24V48 24-HP V-Twin Automatic 48-in Riding Lawn Mower. The 'YTA' in the model number denotes a CTV transmission, 'YTH' is the k46 hydro version. Here is a link to the article and videos on the CTV transmission.CVT Automatic Transmissions – Simple to use, ideal for all terrain.
