I've been talking with Nelson Muffler Co....

Dr. Allis is spot on, bigger opening (1 5/8 vs 1 7/8") for faster gas flow. And if I may ad the 100 series were offered with ROPS & canopies so the taller outlet may have been to help exhaust clear the canopy. FYI, it looks like the 170/175 gas muffler will come in somewhere in the $16X range.

The good Dr has a wealth of information of which I soak up like a dry sponge in water. I am impressed by how much I learned the past 8 years just by reading the posts of the knowledgeable members on here.

Just saw a post on the FB allis group about late D17 Nelsons and the WC/WD style nelsons being available and immediately thought of this topic.

Kind of stoked to have the original WD available, as one of mine has the WD-45 manifold (and I have a Nelson for it), but now I can get a Nelson for my older manifold and get rid of my crappy third stanley.

Often times, a working tractor may encounter and occasional low hanging branch, on  the edge of a field.

I can my mufflers with tin cans.  I can reach the can from the ground.  If the muffler were to be extended, it would be difficult to can and un-can the muffler.

Thanks Lonn for that !! That was my original "CRINGE", guys wanting to blast holes in I would assume perfectly good/straight hoods for the sake of what another poster said- TONE.

I had some time today to run numbers on the potential market with each model of tractor. Now the following numbers are just my BEST GUESS, and are based off my own observations in my part of WI, and the calls i've made when I researched the D17 oval muffler. So these numbers possibly would be different in other parts of the USA. I do need to point out that during my research for the nelson mufflers, the consensus is that 99% of guys who use their tractors for farming or who work their tractors, will not fork out the additional money for a Nelson muffler and will instead put a stanley on and keep working.

D10, D12, D14, and D15 series I gas tractors that used muffler A-C #227240/233450: Total made is 47,150.

Out of the total, I guess 50% are still floating around not in a salvage yard, or scrapped. Which makes the total remaining: 23,575.

Out of those tractors, I guess 75% are non-working tractors or restored which might get a Nelson muffler. So the number of prospective Neslon muffler buyers is 17,681.

D19 Gas tractors that used muffler A-C #246130 total production was 7000

50% are still floating around not in a salvage yard, or scrapped: 3500

I guess 75% of those are not working tractors, which might get a Nelson. So D19 Nelson muffler prospective buyers: 2625

D17 Late GAS tractors total using muffler A-C#246129: 39000

50% not in salvage yard/scrapped: 19,500

D17 late Diesel tractors total using muffler A-C #237290: 7990
