I hear your question and by the number of 230 something that has read this thread hear ya, but what does it all mean. Why should it be there and not any other place to get true numbers???CaptainQ said:

Kubota does the equivalet test in Japan and does not want to pay the Nebraska folks to test it again. Or so was posted here in the past.
Personal experience is that Kubota is nearly always conservative on specs. If they were full of puff, that would be out there loud and clear. It isn't. Take that for what it is worth.
Better yet, demo a Nebraska tested tractor and a Kubota that is spec'ed out just below and just above it and perform identical tasks and see for yourself.

The Nebraska tests are really ment for large farm tractors, its not really a program for CUT's. I've also heard from other vendors (not Kubota) that Deere funds most of the program and they feel that they get preferential treatment. Its very expensive to get a tractor tested, and there is a queue of several months to get a machine run though. I'm not sure how long this program will last yet, there has been legislation to ax it several times but its never gone though. There has also been talk of Nebraska accepting the test results of the other international testing labs. For some reason they refuse to do this, Nebraska is the exception to what the rest of the world does.

How come on their website some of the testing locations show some university in Italy? Are they performed by the Nebraska, just on location?
for example from the TN70DA test, qoute, "Location of tests: Alma Mater Studiorum, University
Di Bologna, Via Gandolfi, 19-40057, Cadriano,
Bologna, Italy"

maybe they are taking results from some other labs now, I know for a long time thats been an issue.

NE Tractor Test Laboratory
"The University of Nebraska Tractor Test Laboratory is the officially designated tractor testing station for the United States and tests tractors according to the codes of the Organization for Economic Co-operation and Development (OECD). Twenty-nine countries adhere to the tractor test codes (including non-OECD members: China, India, the Russian Federation, and Serbia), with active tractor test stations in approximately 25 of those countries. The OECD codes require that tractors be tested in the country of manufacture. Reciprocity agreements with the codes require that once an OECD test report is officially approved, it must be accepted by all participating countries."

It looks like they are now coordinating with labs outside the US:
Tractor Test Laboratory organization
But you will also notice that one of the boxes in the middle of this organization charts is 'US Tractor Manufacturers.' I have no idea what that means but it raises red flags in my mind. The organization chart also looks pretty complex.
I'm sure its the skeptic in me, but it is easy to see how there might be quite a few competing influences (read:conflicts of interest).
I can see how Kubota might not want to play ball with them. Especially since it is primarily aimed at ag tractors.
I think the only way for an organization to be above suspicion is for it to be totally autonomous, accept no advertising and provide no endorsements. Like Consumer Reports. I would guess that their organizational chart has one box.
I'm also not sure why this process has to be so complex. I understand that testing at the drawbar is the most important figure for a farmer and that many factors can influence this. It seems to me (naively I'm sure) that testing horsepower and torque at the PTO output shaft and at the rear axle would give sufficient data and would be much easier to test.

Kubota is beginning to have some tractors tested at the NE test lab. Several models have been tested and more are to come. The lab tests fuel comsumption, drawbar and pto hp, 3 pt lift capacity, hydraulic pressure and flow, weight and other parameters. Tests try to be standardized to type of fuel, air temp and humidity. Tractors are suppose to be broke in by the manufacture and ready to go. No adjustments are allowed once testing begins.
