The One-Ninety XT Story for new members

Allis-Chalmers introduced the One-Ninety in 1964 and the Xt's in early 1965. The produced the One-Ninety Xt's thur 1971. During that time they built a little over 22400  Xt's.

I have seen some of the 190XT series III's with the 540/1000 PTO like the mighty 200. What year did this come about?

The dual pto was offered in the later 1970's  I don' t think there was a serial number break to pin point the time  that it was available.  It was an option.

I've got a very nice set of series II or III flattop fenders for a 190 for sale.  Were only on the tractor 4 years of its life.

The story behind the story is this.  Marketing had finally figured out that the future in the big tractor business wasn't a tractor where the operator sat down in the dust with his legs wrapped around a hot transmission.  They asked engineering to design such a tractor with 75 hp.

Engineering (foolishly) did just that with no room for hp growth.  JD brought out the 4010 at 88 hp (only at Nebraska did that ever happen) a few months after the 190 was introduced.  Of course, marketing was on engineering's door step the next day wanting 90 hp, and they wanted it right away.

The engine people said, "No problem, we'll just add a turbo."  The drivetrain people said the drivetrain would fail at 90 hp.  The marketing people said they didn't care, we need the 90 hp right now (their commission checks depended on it).  The rest is history.

  Very good to see the discussion of the 190, i had and sold one and now have another and have questions about it and will appreciate any help!   I bought this past summer a 190 to use for mowing baling etc, and am doing some of the touch up things I want to do.  It was sold to me as a 190, however on the torque tube is says 24505 xtd. my serial number books say both 190's and 190 xt's were built during the 1969 time frame so what is it? xt or not?  It has a 2800 diesel engine and dynos at 77 hp. But my I&T manual says there is a transmission Serial # and Type number. Can a person tell the differences and does somebody have a transmission serial # reference and would it tell use what type of transmission?   The Serial # is  C169169  Type 7.842.  So what is this tractor and is it from factory that way or is peiced together.  I do know Allis and other OEM's will some times put parts together ( that don't match supposed to be )  to finish a run . I do like driving this one,i think it is better than my 185 and just fun to be on. Tractorman

 I understand the whole 190 non turbo,190XT turbo. What is the difference between a 190 gas, and a 190 XT gas? Was it the 265 on the 190 and 301 on the XT ? If XT meant it had a turbo, why was there a 190 XT series III gas ? As far as the pto goes, you could get 540, 1000 or dual. With dual it could be hydraulic ingagement,on the console or the big lever on the left. I think that was a killer on the 190 also,no true live pto. It is still my favorite tractor though

   According to Norm Swinford's AC Farm Equipment 1914-1985, pg. 103 bottom of left column: XT doesn't stand for anything. We just liked it.

Hay HagenAC how much for the series III fenders?   THanks Mark

from what i heard the the 190xt was originally going to be called the 190xp because of the "extra power" but i guess it was decided to change it to xt just because it sounded cooler and catchy. i have a gas 190xt with the snap coupler hitch. its a early model with the full fenders and it pulled around 85-86 on the dyno before the clutch started to slip. but otherwise its good running.

Thats true on the gear jump out , guy i know was driving a new 190 around the dealers lot and it jumped out - thats not good advertising

I'll try to answer some questions, hopefully shed some light on  the 190 story as i saw it.

All the way back to Richmar's original post... I was always told Allis switched to the 4 pinion diff. at the same time as the larger axle, so if you found a 190 with the large axles you have a 4 pinion diff. is this true?  our 190xt is a ser. 1 from the bell housing forward and a later ser. from the bell housing back with large axles and 4 pinion diff. we bought it in 1975 used, with new paint:) Must have been a driveline failure tractor.  It was an awesome tractor for us ever since.  I wonder if these serial number questions are due to rear end swaps like ours.  Here is ours today.  I am thinking about painting it again.  I restored it in high school, in the 90s, wrong color and has the wrong decals, all I could find at the time.  The aftermarket has come a log way:)

We had a series I that Dad bought new in 1965. AC made two upgrades to the rear end 100% at their own cost. The third time was at Dads cost. I don't know what was changed each time. I know he traded it for a new 1971 series III after that, so it was 4 or 5 years old when the rear end went out the third time. We were having trouble with the hydraulic pump when it was traded off. The series III never pulled as hard as the first XT did but in 5 years we never had any trouble with it.
