We are looking for a good tractor for a 40 acre place. I need to know if a 8n is enough tractor or should I be looking for a ford 2000 or 3000. I plan on shredding, plowing, doing some road work, etc. I have had conflicting reports, some say the 8n rates at 27 h.p., and then a so called expert said it was 21.95 h.p. So which one is it?

Andrew, For what you want to do on your 40 acres an 8N is more that enough tractor. Plowing is its strong point, this is what it was made for. Running equipment of the PTO,in my opinon, is its weak point. Not that it can not be done but a live PTO is nicer. I have a 52 8N and do all the work that you described in southwest WI and really enjoy it. You might want to take a look at the 600 or 800 series of Ford tractors for the live PTO & live hyd.

The Shop Manual says: (8N) 27.3 hp. at belt pulley. 23.2 hp. at Drawbar. What does the rating at drawbar mean? How is it measured?

Correctly. One horsepower is the amount of energy it takes to lift 100 pounds 1 foot in 1 minute. In electrical it is equal to 746 watts. Its been a long time. If IM wrong someone will jog my memory.

For the 8n, 3 official tests(with different results !) were performed at the university of nebraska. If my memory is good, it was in 1947, 1948 and 1950. The first and second were done on old 8n and the 1950 test was for the late 8n (those with the distributor on the right and the generator on the left). The engines of the late 8n have a higher compression ratio as compared to the old engines which are 9n/2n style. It is difficult to report the exact HP from Nebraska tests because a lot of tests are performed when a tractor is tested. More on that, many books had reported tests but they are only summaries of these tests. I would say that old style 8n have approximately 25.5 HP and for late 8n, 26.2 HP maximum(2000 rpm ?)at belt or pto(?). Mr. L. Leviticus could explain all the tests performed.
Regards, Dave Donov.

Ford Motor's figures for the later 8N's was 27.32 @2000 RPM, 23.22 85% Max. belt HP. These were used in Ford publications at that time.

Andrew..... ..University of Nebraska tests rated the 8N at 25.5 hp PTO and 20.8 hp drawbar. Ya kant gett more "accurate" than that. And you know how accurate the advertized hp on any automobile is, right?

Theres quite a story behind the UN Tractor tests and has to do with the "original" Ford Tractor manufactured in Minneapolis by a snakeoil salesman named Ewing who named it after a friend named Paul Ford. (hoping to capitalize on the fame of the real Ford Motor Co) Which is why the first Ford tractor was called the Fordson cuz ol'tightwad Henry wouldn't buy the Ford Tractor name from the Ford Tractor Co of Minn. Big stock scandel and scams involved too.

It was a piece of junk and caused a Neb Senator Crozier to pass a law that said "if'n you wanna sell yer tractor in Nebraska, ya gotta get yer tractor power measured by the Univ Neb Engr Ag School or else". And everyone that wanted to sell tractors in Neb did.

Henry designed the 8N for 160 acre mixed farmstead so you can do everything you need to on your 40 acres. 8N's don't have all the bells and whistles of a modern Yamabotadeeer, but consider the price difference and that you can resell your 8N for what you paid for it a couple of year from now if'n ya decide ya just gotta have things like more horsepower, powersteering, live hydraulics, live pto, ROPS, monthly payments..... ..Dell

Wasn't the story that the Senator was driving his ford (not henry ford) tractor home from the dealer and it broke down, thus upsetting him so that he started the legislation that lead to the Nebraska Tests?

ED..... ..donna know, just a littlebit before my time (grin) but he was one p/o dude and had the legislative power to get something accomplished. Don't forget that there was a lot of gettrich schemes going on trying to capitalize on an emerging industry with fraud and deceit. And farmers were fair game because of their sophistication, wealth, and desire for living eazier..... ....Dell

Depends on what you intend to do with it. I have thirty-five acres. I cut all of it with a finishing mower and hog brush (as my wife calls it). I also have post hole digger, double disk, seed spreader, rear blade for snow removal etc., and rear bucket. I have used all emplements and the 2N does a good job.

I think technically, 27 hp. However, realistically 21-22hp. I would 40 acres would need something a little bigger.
