Would you suggest one of these over the other: 2006 Kubota BX1850, less than 500 hours with belly mower $5000 or 1999 NH TC-18 650 hours with belly mower $5000? I'm guessing the newer Kubota is the better deal but I have zero knowledge about either of these machines so maybe the 99' NH is a better tractor, I really don't know.
I would probably go with the BX but that is not seeing both tractors. I am not sure but I think the 50 sereis BXs had a problem with a abrupt stop. I think there were updates to the hydro to correct it. It is something you may want to research.
