Ok guys help me out with the rain caps on top of the muffler. Do they flap back toward the driver or toward the front of the tractor. I have a Cub and a A.

jg,
When those tractors were built the raincaps did not flap at all...nary an IH gas engine had raincaps in those days. First IH tractor with a raincap that I saw in Iowa in the 1950s as a teenager was an M Diesel.
I couldn"t imagine how the driver could put up with all that banging racket....and I still can"t imagine it!
Standard equipment in the toolbox on my Farmall is a Campbell"s soup can.

Which way to turn them is a matter of owner preference. I keep them on my tractors due to taking to shows, parades, etc., when they are home they are under a shed. but i prefer to turn mine so the flapper deflects the exhaust away to the left.
 
Only one that ever made noise around my place was on a B John Deere, now that thing drove me nuts and I had to take it off. The rest of my red tractors are in proper tune and they don't "bang" as you put it.
 
It's all a matter of personal preference.I like to have mine open to the front.You can put it on any way you want.
 
jgstrickland, As other have said it is preference. Over the Yrs for Me it has worked out that most of the time My tractors pointed North, into the Prevailing winter time wind. as the case was when I was in the Okla. Panhandle! What started my change from facing Forward to Rearward was seeing high North wind open up the rain caps! So when our tractors were all home for the winter and in a row we changed to opening rearward so the high North wind would keep the cap shut instead of trying to open them! Consequently I still prefer My rain caps to face / open rearward. Also in my Tree infested country many times I have skirted under limbs and the Rearwards opening cap doesn't get caught on small whippy limbs and such!

Can't stand the noise and they were never on my tractors as built. I use a polycarbonate yeast jar, doesn't rust, makes no noise and it is very light, has rounded corners, just fits over the exhaust pipe and sits in the tool box when not in use. If it is left on while starting it takes off but as so light and the rounded corners cannot hurt anyone or paint!
 
Those rain caps are noisy and if they face the front they are great branch catchers so i just dont like them at all. I like to put a curved pipe on,there is no noise and never catches any branches.
 
Yea,you opened a real "can of worms" here! lol (Everyone will have an opinion about this one. ;)

Mine at low idle drives me a little crazy sometimes. If you are running it at higher RPMS,or all the way open,it does not really matter because it should be fully open and not "banging" against the top of the pipe.

I have mine with the hinge at the rear. The one advantage of this is the "flap" tends to disperse the exhaust away from your head when you are running the tractor "full bore" at high speed out in a field . (It makes a difference with me anyway.)
 
exhaust coming out of the pipe hits the angled open cap and deflects.
So, I put mine 45 degrees out from front.
Straight forward, and you will drive right thru the deflected gases.
straight back and you will gas yourself.
Flappers are 'cool' and I have a few, but on my working tractors I much prefer an automotive tailpipe turn down.
Pointed the same, out 45 degrees from forward.
And on tractors with a very tall exhaust....nothing at all.
blowing straight up and the tractor moving forward,
by the time the exhaust falls to your level...ya ain't there anymore :D
Smell isn't the issue. Ya gotta deflect those tiny little hot cinders away from you, especially into a headwind.

all my verticals get a bucket over em when parked. Blowing snow gets in no matter what end you have....
 
Ok guys I figured this would be somewhat of the response that I would get. So I may put mine on side ways just to be totally different. But seriously, thanks to all who had input.

James
 
thank you to all the responses
They have given me a smile on this Canada Day Calibration ( I live Just east of London Ontario Canada)
I have considered using a rain cap as I work on final reassembly of my 123 engine on my BN. I like the repose of THE Polycarbinate Peanut butter jar I can just see it hurtling into space when one forgets to remove it before starting { If one is fast enough One might even catch it on its way down}
Thank you for the smile and the information that I may place in my bank of ideas
 
Mine are set with weight over the hood.

jg,

Hope my reply did not offend you...just the ramblings of an old guy who lived the era of new M and H Farmalls.

I use a Campbells soup can and yes I have forgot it when starting and it flies way up high and coming back down it almost always hits the nice paint job.

I used a plastic can once, put it on too soon after running, and it melted itself tight to the muffler.

PS The Campbell Co., years ago, made their cans specifically for Farmall mufflers. Many people do not know that.

PSS I have been thru your area a couple times, very nice there. Attended a plowing contest west of London a couple years ago. Fun to watch.
 
Whoops, got Strickland's note mixed up with another note about living near London...sorry about that.

A day early, but...

HAPPY CANADA DAY to all our neighbors to the north! All of you add a touch of class to the citizens of the continent. I admire your manners and politeness every time I talk to any of you.

I agree a tuned up tractor,they don't "bang", even at the slowest idle. its when the tractor has a miss they sit there tinging away.
 
Forward or back, they tend to catch on tree branches.

We always put them out to the side, but here is where Dad and I differ on the subject:

1. Dad mostly doesn't care, but tends to put the mufflers on with the weight toward the middle of the tractor.

2. I am OCD about it, and I have to have the weight to the OUTside of the tractor. I.E., when the exhaust is on the left, the weight points out to the left.

I personally don't care whether it is factory or not, the tractor just looks out of place without a rain cap to me. On top of that, while it's fun to shoot the soup cans to the moon, it's no fun when they come down on your head or the shiny paint. Moreover, all you have to do is forget your soup can just once, and you can end up with expensive engine damage.

Given the amount of noise these tractors make, the occasional "ting" from the rain cap at idle seems inconsequential to me.

I use this type, they don't "bang" at idle. I turn the hinge to the rear, bad habits as so hard to break.
 
I grew up on a 70 acre farm on Lake Ontario. My father bought a Farmall M the 2nd day we moved in. My father always had the rain cap mouth facing the radiator. It was the tractor that made me love the IH Farmalls and I still have it today.


Even when this one time when my father replaced the muffler and it didn't have a rain cap, I asked him to get one because it became iconic to me just as much as the Farmall red.

Oh and it had to face the shroud!
:lol:
 
My Dad always turned them with the wieght towards the front. He said tha way when you were mowing and go under a tree limb it pushes the cap down intsead of ripping it off. 8)
