I do need to update my previous post....
I now own none of the mowers that I mentioned. I have switched to John Deere. So now I will be using a 2010 Z925A MOD. If things go well this year I will be picking up the quik-trak from john deere this fall or next spring.
I made the switch because of dealer support.
