Why a muffler on the 200?

190 should have a muffler under the hood. At least mine does. Straight pipe goes on top of my muffler

Because of those two things on each side of your head. I think they are called EARS.

I think very late XTs had mufflers. The reason why mufflers were added is because noise levels were starting to be paid attention to.

Lonn, What is "late model"?? We have a '69 XT and DEFINITELY has a muffler, thanks.

My late 1968 has none...straight pipe only. And I love it that way. Can you hear me now? lol, all kidding aside they are quite loud. The long pipe made it more barable vs say a shorter pipe. My brothers 1968XT has the factory cab, and it has a external round muffler!!!! Only 4 serial numbers off. Mine is 20346, his 20350. Probably built the same day and obviously went to the same dealer. We bought them both 49 years after production in the same area they were sold in. Tell me that isnt awesome! If you have never heard a 190 XT with a almost 4' long straight pipe mowing hay at 1,800 rpm you are missing out on some beautiful music.

Somehow I turned into an old guy.I despise loud exhaust. I like quiet horse power.

Here's what I grew up listening to and why I have hearing aids today as dad didn't do hearing protection back then.

Let's address the original question and try and correct the misinformation on this post. The reason for the muffler was to reduce engine NOISE !!  The 200 got a pretty nice factory cab and it was time to help keep the noise decibels down as low as possible for the operator. The 200 had a 6 inch hole cut into the hood to accommodate this new muffler. Hood p/n of 70256268. There was never a 190 XT turbo diesel that had a muffler from the factory. None...zero...zip...nadda. I don't care what AGCO parts book says. There are plenty of mistakes on some of those since they went on-line. 190XT turbo diesel hood p/n is 70250680 and has a 3 1/2" hole in the hood.  Any 190XT with a muffler has been added on plain and simple and maybe even had a bigger hole cut in the hood by someone. A-C never had a small hood hole with a muffler body above the hood like an IH tractor.

My 220 arrived with a straight pipe.That sucked! I cut a big oval in the hood and put a 7040 muffler on it.Saved the piece I cut out .....  That hood is not a piece of tin or sheet metal.Must be at least 11ga.Used a saber saw.Turns out,the fan ROAR is rediculas!

Did some checking on the Agco parts system; part # 70250632 serial # 19001 and up-"
MUFFLER "

I added a muffler on the 190xt, later traded for 7000 because of ear ringing at night. After 39 years 7000 still working and has never had any troubles we could not fix at home.

I was thinking in the Allis book there is a picture of a 190 with Muffler. Maybe this was only in the prototype stage and they decided one was not needed.

One-Ninety's gas and diesel after s/n 19001 and up had a MUFFLER above the hood. Previously they had a horizontal muffler underneath the hood. The tractor in question is the One-Ninety XT turbo diesel, which as I said, never had any kind of muffler.

The Doc (as usual) has it right. We had one of the very last 190XT III diesels built and it had a straight pipe. The first 200s were on the dealers lot and they had a muffler. Never was a 190XT diesel  built with a muffler and never was a production 200 built without one.
