Some input and thoughts on what's been said here...
Production is now slated for August, reason given being overwhelming pre-orders, as was the issue with the RSD. And as with the RSD a whole new production line is being built for this model. Tranny shortage would delay regular RSDs too, and there's no sign of that.
Country Clipper is the brand that has flip up decks. They are manual and I don't hear much good about them.
I would not expect to see this on commercial models. It's got a specific audience, IMO. Leaky Gasket is one of them. It's for the older fella with a decent sized lawn who takes care of his property and his equipment really well. But maybe they aren't too spry, no offence LG! It's a retired guy mower. Easy to clean, and electric deck lift means no stomping on a pedal.
$5k+... Yeah, price is climbing. But the normal RSD is still very well priced and featured versus the competition...then you added a crap ton of pricey tech. Really, it's a fair enough marker. And for the intended market it's worth it- a hydro lift is fine for younger folks, but not so much retirees who will see the value in saved aches and pains versus dollars.
Note that th castors are 9" instead of the RSDs usual 11". IMO that also makes it a 'smoothe lawn' mower. But that fits the intended audience, so all is good.
