Muffler for AC 720/Simp. 9020

[DoubleT 0]

Does anybody know where we can get the mufflers for the AC 720,620,Simp. 9020 and 4041 tractors other than at AGCO or Simplicity?? The price is outrageous and it probably fits other tractors as well. Any clues to solve this problem? Tnx, RoyG

Roy, Been there done that just this week. Didn't do it. I contacted Nelson muffler to see about buying mufflers for my re-power kits I am working on. They will make me mufflers to my specs including flow volumes and back pressure, and physical dimensions. The only catch is I pay for the engineering and developement cost. The mufflers would be mine, and they would sell them to no one else. They will not sell anyones design to anyone else. This is called proprietary drawings. If I went that way I could probably sell you a new tractor cheaper than I could sell you a muffler, based on the volume that this business would generate. My next prediction: "Get ready for parts and short blocks on all of these discontinued engines to go up very quickly and a lot of no longer available parts to show up". When these engines are in production the short blocks can just be part of a production run, when they are no longer allowed to build these complete engines as is now the situation with all K and M series Kohlers and The 243000 and 32600 series Briggs and VM and HM series Tecumsehs, Short block lines will probably be set up and torn down. Every time they make a run,all of the set up and tear down time will be divided into the quantity of the run. As volume goes down the cost goes up. There are no 243000 or 326000 short blocks or engines, only parts. On many of these old parts I am surprised they are still making them at all. Worse yet the EPA wants all of these old engines out of service and replaced with new environmentally friendly engines, and they will have some influence with manufacturers. But be assured the old rule of economics, when the volume goes down the prices will rise. Quite likely if we were a stockholder and this didn't happen, we would probably dump the stock. My 2 cents worth and it is free so let that explain its value, Al

DLC was right about Nelson making many of these mufflers and did promote some of them a few years ago. However, Cummins Engine Co purchased Nelson and a lot if not all of that disappeared. I few weeks ago I had to make a purchase from them for the place I work. Instead of getting Stoughton Wi (Nelson's home office), I was promptly wisked off to a service center of Cummins on Georgia.

DoubleT is right, they do have them. BUT, You have to rely on "Tomahawk Engineering" to use one of the 'Trapps'. I sent him email, the response was Yeah we carry em'. I was not very impressed. Especially for someone who offers (in my case) Simplicity parts. If I want a hard time and get "it might fit, kid" I'll do it close to home. You'd think they'd have a good idea what would work. Especially for the 'large frame' garden tractors like the 3000 - 7000 series (the big singles). The problem is the pipe wraps around the front then goes into the 'beer can' then the muffler exits from the same side it enters in on. If you use one of the threaded jobs, it sticks straight out or 90 it straight up. If you had a 180 adaptor under the hood and could attach the spark arrestor version and still be out of the way of the PTO. That would be way kuhl.... Yet another 2 cents! Any others????
