If ya think about it the Nebraska test are in fact testing HP and Torque. When you hook up the PTO/belt and test the way they do they are applying drag. As more drag is applied both the HP of the engine and Torque come into play to keep the engine running at RPMs. IF you built 2 engines of the same displacement, one short and one long stroke but with the same HP rating, bolted them to your tractor tranny you would get different test results hooked up to a dyno.
They are just putting out the test results in a rating of HP. My thinking there is that when tractors and powered inplements were first coming out the average person had very little if any education. They listed the implements with one requirement, how many HP to run it and sold the tractors the same so a person could match them up. Why confuse the situation with a combo rating that the buyer may not understand. Heck I bet most pickup buyers today buy based on HP/Torque ratings and have no idea what it means to them towing a trailer down the highway other than the idea that more is better! In fact that may be a better idea.....rate turcks by payload/towing and HP at the tow ball.

Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
