There is no passing or failing the Nebraska tests. The tests record measurements of the performance of the machines.
The primary purpose of these tests are to provide drawbar and PTO performance ratings, including hp and fuel efficiency.
Most companies do not advertise the drawbar HP for small utility and CUT tractors, and haven't for years. When the primary putpose of the utility tractor was to pull a plow or a disk this was a very relevant number. In this day and time when the utility and CUT is used for more varied tasks the drawbar HP has lessened in importance.
The PTO hp remains an important measurement, but the average retail customer relies on his/her dealer to match up the proper PTO driven implements to the tractor size.
Here is a link to the tests done from 1999-2004,
Tractor test reports. The bulk of the current testing done is for the 100 hp and above market.
Here is a link to the 90-99 tests:
1990-1999 tractor tests
As you can see CUTs by and large are not listed as being tested.
I am curious as to why the original poster was comparing a TN65, which is a utility, to the Bransons, which are CUTs? Those tractors are not really comparable at all.
