That used to be great advice, but with only Kubota building their own smaller tractors here, it's not nearly the benefit it used to be. When I set out to buy a new tractor I researched all the big names, got prices, read feedback, looked at every forum I could find, and came to the conclusion that the major brands are getting their butt's kicked in similar fashion to what happened to the U.S. auto industry not that long ago.
If I'd bought my new tractor from NH, it would say Boomer 50 on it, and it would have cost me $8000 more than buying it from LS....for the identical machine. If parts availability is going to be a problem down the road, it will be for a NH owner as well, so buying the "major name" gets you nothing but added cost, in many cases. That also means the same situation is likely happening when you buy green, or red, or any other color....you're not really getting the benefit of guaranteed lifetime parts and service like you used to.
If they aren't making it here, in their own facility, there's a risk involved as a consumer, and you're not even getting a discount for that risk. Seriously, $8k more for the same machine....that says something just ain't right.
