Just when I finally decide to put an end to all the research I've been doing on residential zero turn mowers and go look for a Raptor 52" I see this http://www.youtube.com/watch?v=NTULVAHgf-M The teaser says bigger, faster, stronger... available November 2013 and that is it. Well I don't know if I need bigger or stronger, but I might like faster. Has anyone heard any more details about the SD? Is it going to replace the regular Raptor? I am also looking at the Husqvarna MZ5225 (upgraded hydros, faster top speed, larger rear wheels), but it is about 50% more money than the Raptor. I'm trying to decide if I gamble and wait to see if the Raptor SD would get me closer to the MZ5225 specs for less money. I will only be mowing my relatively flat ~1.5 acre yard. Thoughts on this would be much appreciated, thanks!
