H mufflers...ah yes, there were several types I remember seeing on the new H's that came to our Farm and the local dealer (Keith Williams International Sales, North Adams Mi.) The new '41 H we had had a baffleless dark gray muffler with about a 3 inch long outlet pipe and about a 12-13 inch long body. I don't believe this muffler had a total baffle but the inner pipe was perforated and there was a restrictor sort of baffle (down to about a 1"hole) about halfway up the pipe. The ends were rollspot welded to the inner pipe and body with the top end fitting over the end of the body and the lower end slipped inside. It was moderately loud but not nearly as loud as the tractor with no muffler at all. My uncle used to take it off when he ran the belted hammermill grinding up ear corn for feed...and the old H "barked" a lot louder then.
About 1944 or 1945 the new H's came with a longer silver colored muffler with a long outlet pipe..about 10" I'd guess, with a smaller diameter than the inlet, down to 1 1/2" I'd guess. The top end had a "bulged" appearance, but the bottom looked the same as the older mufflers. The ends were welded on the same way as the older ones The body was about 12-14 inches long. I never saw one off so I don't know how they were baffled or the inner pipe punched, but they were quieter than the older ones...and looked better too. About 1948 the new Farmall H's and M's came with nice silver mufflers with about a 10" long outlet pipe on the H muffler and 12" outlet pipe on the M's. The body of the H muffler was about 12-13" long and the M muffler 15-16". Both ends of the mufflers appeared to be spot welded to the inner pipe but roll-crimped to the body...there was a crease about 3/16ths high around the end crease where the ends were joined to the bodies. These mufflers were fully baffled but the inner pipes were heavily perforated below and above the baffle..and they were pretty quiet on both model teactors, the M did sound louder than the H which was really quiet...but it was much quieter than previous M's had been.
My uncle bought a new H in February of 1950 with that newest type of muffler, it was really quiet but sounded downright nice working at open throttle speeds....a sort of "packed but powerful sound".
When the Super M's came out I noticed they had the same muffler as the latest M's had had except the outlet pipe was larger..about the same diameter as the inlet actually....And Man, they did sound good...a lot like the new H did except louder and made the tractor sound like it had lots and lots of snort....and it did, as we all know.
That's my memories of the Farmall H and M mufflers. Funny, I'm 77 and can remember that stuff real good...but something really important....nnaaahh, gone for good....
