My 1650 gas still has the sticker on the left side that was the certification of horsepower. I remember years ago it was a bragging point of the Olivers.
My question is how was the horsepower certified. Did the go from the numbers at Nebraska test or did the dyno every tractor and sign off in it? I have never heard a discussion of what the certification actually meant. Did all the tractors of the same model have the same numbers on them?
Some of you guys with the company have to knopw the answer to this one.

A good friend used to be one of the dyno operators and would sign his name on the decal as well as the horsepower. I kidded him that he must have used disappearing ink as most of horsepower numbers and the signatures tended to disappear.

I can't read the rating or signature on my 1650D either. I remember well our 1750D was certified 86hp, our 1755 at 92hp. Neither are readable today.

Don-WI is correct. Every tractor that came off the end of the assembly line was hooked to a Dynometer.  They had multi Dyno's.  If the tractor did not meet the minimum HP for that model it went to the "bull pen" for correction.  The horsepower that the tractor produced was written on the decal and signed by the dyno operator.  This practice began with the "50" series and continued through later models.

Okay, 'nuther question along the same lines. When did they quit issuing "certified" stickers, and what was the name of the inspector who signed your sticker? On my 1650, the name was Vance. Jim.

I have one on the 1950 or 2150 that still shows the signature. I remember looking at it one day and wondering who this person would be.

Jim, I would like to add to what Mr. Starr said in his post.

On February 24, 1971 a letter was sent by H. D. Ralph, director of services at Charles City, to all regional sales managers, supervisors, and any other regional or territory managers.

Part of the letter states:

#1 "We will immediately cease to affix the certified horsepower decal on production tractors."

#2 "When advertising literature is reprinted we will remove the paragraphs that play up and explain certified horsepower."

#3 "We will continue to show on the specification sheet 'Horse-power (certified)', and show the same ratings. For example 86 horsepower on a 1755 model. This practice will continue until a new model is introduced that could be sent to Nebraska and tested. When a new model is introduced the first advertising literature would show in specifications 'manufacturer's horsepower rating' and then after the Nebraska test figures are available we would show the Nebraska test horsepower figures in all future advertising literature."

The letter goes on to say that Oliver would continue to test every tractor coming off the Charles City production line. The only change would be the decal. There was another letter from M. L. Grimm in sales planning dated April 29, 1971. That letter was shorter, but said nearly the same thing.

We all know when certified horsepower started, and now people will know when it ended.

So then a late model 1855 wouldn't have one? I don't ever remember seeing one on our 1755 either, but the 18 was overhauled and painted before we got it and it has one of those roproduction stickers on the lower left side of the dash. The guy also stuck both the Hyrda-Power and Hydraul-Shift decals to the hood.....
Oh well, just have to repaint it and put new decals on it eventually....

Yours is still readable? I always thought it would be neat if you found one that was still original and readable.

Mine is readable, but the horsepower and signature is long gone. Thanks to all who answered my post.

I think it was in an article in Oliver Hertage a year or 2 back. Seems like they Dynoed every tractor, and if it didn't make the minimum requirements for that model, it went back inside the factory till it did.

So I guess every single one of them was tested and signed off.
