Meadows of Dan Farm service is still there, I bought a box blade from them last year. The still have some NH tractors on the lot but I don't think they are a dealer anymore. Not sure what the whole story is behind that, but they had lots of new-old-stock tractors/equipment, etc which tells me they weren't willing to deal on a lot of stuff. There are 'new' tractors and backhoes there that are 10+ years old. In the show room there are 'new' Stihl chainsaws that are many years old (like a 009 and 038) and new generators that look to be from the early '90s. The box blade I bought was a NOS unit almost 20yrs old (I paid full MSRP for it, but it was still a good deal as that was a mid-1990s price, lol) Kinda weird, but an interesting place.
As for the dealer in Wytheville, Fowlkes Machine co hasn't carried Ford/New-Holland for many years. A couple years back D&H from Chilhowie setup a second dealership in Wytheville but couldn't make a go of it. I guess there just wasn't the market, they folded in about 6mo.
