[AT] [Somewhat] New muffler for the [John Deere 620]

[dean at vinsonfarm.net]

Dean VP, whew, sounds like I dodged a bullet concerning the potential disintegration of that dented muffler on the 620.  Some wise person I know advised me a few years ago about what to look for, so the 620 has been equipped with the non-dent correctly-baffled version for a while now.   For fun I just now made a little video as a companion to the Super M muffler test:     https://www.youtube.com/watch?v=l20HQWnm2yM  

 

The green tractor also didn’t come up empty-handed in this latest purchase from Steiner… in addition to the muffler for the red tractor, I bought a replacement cushion for the 620 seat backrest.   Haven’t gotten around to putting it on yet.    ;)

Dean Vinson,

 

I just looked at some old pictures of your 1958 JD 620 muffler, the one with a dent on the side for a steering shaft that isn’t there on a 620.  If and when you get around to ever changing that “life threating” deficiency make sure you buy a muffler that has the original JD baffles in it. The sound is different from the run of the mill aftermarket mufflers on the market and of course doesn’t have the dent in it.   Right now I don’t remember if JD still sells that correct muffler or has gone cheap.    Steiner sells a restoration quality muffler for the 620 with the correct baffles supposedly but I don’t have an references on it.  Detwiler tractor parts used to make a correct muffler but I don’t see it on their web site. Maybe that is where Steiner is getting their muffler.    The correctly baffled muffler won’t have that deep throat sound of your Super M.  The muffler takes away the sharp edge of the two cylinder sound you hear on a straight pipe it is more of a smooth puff, puff.   I didn’t realize how much a difference it made until I put one on my 60.   Even when pulling really heavy loads it doesn’t bark.  Depends on what sound you prefer.   I’m a bit hard of hearing so YMMV. Probably because I sat on  

 

PS: Changing mufflers on the Farmall M before the JD 620 will cause the 620 muffler to completely rust out and disintegrate where all the dents are. 😊 I’m a bit hard of hearing probably because of all my teenage years on a JD 70 which really barked so YMMV.

Not to worry, Dean VP.   And in the interests of full disclosure, I should mention that I likely won’t lose any sleep if my hunt for a six-cylinder ends up being met by a 4020 rather than the Oliver 77… 😊

Dean,

 

Thanks for the clarification.  For awhile I was afraid you were going to the far side!  😊

Thanks, everyone.   If it doesn’t rain too much this weekend I’ll need the tractor to haul chainsaw and firewood around, and am looking forward to hearing that sound again.

 

Of course, as I’ve probably mentioned in the past, this Super M was always the best-sounding tractor ever even before it had the new muffler.  Unless I’m using the JD 620, which is clearly the best sounding tractor ever.   Pretty sure that means I need to keep my eyes out for an Oliver 77.

I thought that name and tractor were familiar!  Congrats on making the calendar.

Yesterday I received one of the restoration quality mufflers from Steiner and installed it on my Super M, and made this little video of the sound test:

There wasn’t really anything wrong with the old muffler, but I’d wanted one of these for a long time.   The body of the muffler is shorter than on the generic replacements, apparently made to the original specs right down to the IH emblem and part number stamped into the side, and they have a deeper sound.   I’m happy with it.

For those who may have received Steiner’s 2021 calendar, this Super M is the January tractor.   They sent me a $25 gift card for making the calendar, so I figured “Hey, time to order that muffler I’ve been looking at…”   ;)
