I would say the ones built for it. Antonio Carraro, Ferrari, BCS, Goldoni. Then, most of the manufacturers have their own specialized models built for vineyards and orchards as well, often built in Italy, like NH V series and more.
I have vineyards and orchards. The vineyards don't require any work done under with the tractor, but the orchards do require it. One thing that makes an huge difference is the mid mounted ROPS, since it folds a lot lower than a rear ROPS would.
Here is an example of my tractor, which they kinda considered it an orchard and vineyard tractor because it has mid mounted ROPS and narrow stance, but it's really too high to be a real specialized tractor. Anyway, no way I could go this close to this loquat tree if it wasn't for the mid mounted ROPS.
It still can't beat the little Agria though, but then again, the Agria was made to be low for this purpose.
