I bought my NX5510 last summer. Came to my dealer in crates; assembly was done at their dealership site. Might vary between dealers though; some of the places that were selling tractors when I was shopping last year were not servicing centers, so I imagine they would have to get them fully assembled. Didn't look like they had any facilities to put one together if they wanted to. That's one reason I bought my tractor from a full-service dealership though, I wanted support after the sale if I needed it. Now my cousin bought a new Kioti last month from my dealer, and the lot was pretty empty. Early this spring their lot was full of tractors, but their inventory has been wiped out. The first time we went over to look, he really liked the DK5310 HST we looked at. I told him he probably shouldn't sleep on it too long, because it was the only one of that model on the lot. He went back a week later and the DK5310 was sold and gone, and the only other open station tractor left on the lot was a NX5010 HST, which he bought immediately before that one got away too. Dealer said he could probably sell a dozen more easily if he could get them in, and 2020 has been one of their highest sales years ever so far. Lot of demand right now, and not much supply. Covid is making a snarled up mess of international shipping for a lot of companies right now.
