Largest deck made?

[Bob]

Huge Yamaha fan here (If they made a car/truck, I would own one for sure).
Looking to find out what size their largest deck was. My Husky has a 54" deck & it takes me ~3 hours to cut ~ 2 acres of grass (which I bag due to it being an irrigated lawn).
I know the YT6700 has a 46" deck (from what I've been told)....which must be triple blade action....right?
I also hear that Yamaha made a YT6800....any chance Yamaha made a 50"+ deck.......and do they ever come with a bagging system?
Thanks for any/all info you may have.....

The 6700 is a 42" deck, the 6800 has a 48" deck, a bagger was available, hard to come by now.
