Sounds like a Presidential ad. After two years with my Rapture SD60 I had to make a change. I mow about 3 acres of grass, half of it with somewhat sloped ground but most with 15% plus slopes and hills leading to my lake. The SD 60 was great on flat surfaces and small slopes but anything close to 15% and your are kinda screwed for traction. (going downhill).it has to be the light weight of the machine. Going up a hill the same hill is almost no problem. I was turfing the crap out of my grass just trying to go down the hill slow. The other problem I was having was a discharge problem. Wow, that deck just sucks. After every mowing I spent 30 minutes or more scraping the stuck on grass from under the deck. It would really stick under the lips of the front deck and just build up from there. I went to the dealer and had them demo me out a Fastrak mower. Much better mower. Well I returned it and went by dealer to upgrades to Fastrak mower. ( that is what I should have bought in the first place) But then I seen this strange looking mower with a steering wheel...so I drove it around the lot and I said, I want to try this one for a week (he didn't seem happy, I think he wanted to close the deal and move on). Well I was completely surprised by the cub cadet pro z 100s. This thing was built like a tank. I tried to make this mower screw up. I went to my biggest incline. Well or 25%. (I know what the book says about anything over 15% incline). I had my seat belt on and bar up. I turned the mower in a complete circle in the middle of the hill and no lose of traction and no turfing at all. Really surprised me. After that I tried to turf my grass. Nope never happened. Anyway I just wanted to pass my experience onto other people. I will be moving to cub cadet forum.
Good luck everyone.
