C.H. Wendels book Nebraska Tractor Tests since 1920 is one of the best books I own. I always enjoy flopping it open and reading about different tractors
Antique Power Magazine did an interview in one issue with the retired manager of the test facility. He told the story of a tractor that was sent to be tested and later aborted because the tractor "didnt meet specs". Nothing is left of this test except the managers personal notes and pictures. Very interesting article. Ill have to see if I can find it-I know I saved that issue

I'd like to see how they mounted all those weights together. For the D14 they needed 9 per side to do the max weight test. That is a lot of cantilever weight on a pressed wheel.

Guessing that would be Lester Larson. He has published several great books about the neb testing.

Dr. Allis and others,refresh my memory. Didn't the Allis price sheets list quite a few of the new tractors as not being for sale in Nebraska? Was that because they hadn't been tested yet?

Seems like maybe during the 8000 series reign?? Think about it. According to the state of Nebraska, you'd have to test four 8010 tractors ( 8010 PD/2WD--8010 PS/2WD--8010 PD/FWA--8010 PS/FWA) so a total of 16 tests just for the 8000 series models. AND, the manufacturer has to PAY Nebraska Test a pretty good sum to do each test. There might have been another situation, but that is one that comes to my mind.

Yes sir. I will see if I can find that issue when I get home. I got rid of most of my old Antique Powers (no longer a subscriber) but I did keep a few that had super good articles, and that was one of them.
I do not remember the company that submitted the tractor for testing, but I remember the engineer was there when they did the testing and according to the article he was a handful LOL

Oliver was one company that guarantied the HP rating of their tractors. If they said it was 45 HP then it put out 45 HP or better.

My "unofficial" fuel consumption experience is kind of like this. A lot of times when baling hay, we'd head to the field with the V rake behind my one ninety gas, and the baler behind the XT diesel. At the end of the field, the gas usually consumed about twice as much gas as the XT did diesel. Big difference though; the gas pulling the rake didn't hardly know it had anything behind it, and the XT was getting a pretty good workout.

It would be interesting to know how much gasoline a smaller tractor (just barely big enough) would burn pulling that V rake under identical conditions. I have no clue as to which AC tractor that might be. I do know that gasoline engines tend to be most efficient at WOT due to reduced pumping losses, but there is far more to it than just that.

I don't think the 8000 series with the power director were tested at the Nebraska Lab.

I remember listening to a couple of conversations between Joe Hoefel and E w Muelhausen (sorry if I misspelled the names) who were the engineer of the AC power shift and the marketing mgr of the 7000 series. AC checked their tractors against Deere and others. The Ne test of the Deere units never matched what Allis tested - they were better in the tests . Detective work found Deere built some units for testing. AC just pulled one off the line - made sure it was up to snuff and put it on the truck. Deere did things like loosen up the wheel bearings, lower the oil pressure, lower the voltage on generators, shave the brakes to make sure there was no dragging, make sure the transmission rolling loads were at the minimun, hydraulic pressures were at the bare mimimun per spec, fuel pumps /systems were exact and on and on. This resulted in a small % increase in performance at the test. They joked they would not want a Deere tractor that was sent to Ne, to farm with - it was half worn out.. Later AC did not build units for test, but did select units realizing not all were created equal off the assy line. In the battle for bragging rights the best on paper and in advertising literature, little things mattered.

I have told this before, but Doc mentioned about the 190 vs 190XT. Recently passed Ray Dogget was the marketing manager when the 190 was introduced. Immediately competition was eating the lunch of AC salesmen in this class as AC 190 had a smaller engine than did Deere or IH or Case and others. It was a time of horsepower wars. Dealers were screaming at West Allis for more HP. At meetings the guys from Harvey simply folded the arms and ask how much HP they wanted as the 2900 could go to 100 hp easily. The chassis engineers knew the limits to the tranny as to hp and weight. They were working on the changes in stages but were 3 years out and 4 with the series III 4 pinon as it required many retooling changes. Ray was under the gun - put in more HP and risk the unknown with tranny failures and meet the demand form the sales force or wait for the platform and keep the warranty cost under control. You know the choice he made. We were in a training class in Mke and Ray in later life was in charge of new trainee schooling. During a bull session one loud mouth rookie blurted, I wish I could meet the idiot who made the 190XT - to which Ray raised his hand for silence and looked at him and said "That would be me" - the youngster then got the full story and later apologized to the class. Did he make the right decision - it will be argued forever..

As a XT owner, I’m glad he took the risk.

So its the Jan/Feb 2007 issue with a CASE 500 Diesel on the cover. It was indeed written by Lester Larson and the test in question was test #385. Long story short engineer Harry McDevitt submitted a tractor for American Steel Tractor Company. A one list of problems were to follow, to include excessive wheel slippage and a transmission housing that got so hot they had to throw water from 5 gallons buckets on to it every time the tractor made a lap.
The tractor was withdrawn and the test stopped. Barium steel of Canton OH eventually sued Mcdevitt and personnel from the test lab were called to court. After the trail, all test data, records and photographs pertaining to that tractor were destroyed and the Ford 8N was given test#385
