Thanks for the link. I see it has a BTS of 15,800 and top speed of 11 mph. The speed makes sense if they don't want those wings decks getting beaten off on rough ground. That would be a good soccer field etc. mower I would think, but for the majority of users I still think the SZ is a better bet for day in, day out use.
I didn't read the entire PDF. Can you mow with only one wing down (or no wings down) like you can with other batwing mowers? I see each wing runs off a belt from the outer spindles, but don't see where it says anything about being able to disable one wing or both while still running the center deck.
