Farmall M versus H Belly Drawbar interchangibilty

Just what is a belly bar i didnt know either one had such. drawbars yes but they arent nor is the swinging one interchangeable
 
(quoted from post at 12:50:50 09/25/11) No it won't work. M 1" thick and 52 1/4" center to center hole. H 3/4" thick and 50 1/2" center to center hole.

The H will go on the M. I am currently running my H drawbar on my SMTA.
 
Yes, I use a M draw bar on my H. I think I had to change the angles at the two bends slightly.
Lays over top the horseshoe rather than below as H draw bar does. I like the added length Of the M draw bar because I run a overrun clutch on my PTO. Mark
 
May not fit the best but have saw them switched before. Lot depends on how thick the drawbar is and what casting is bolted to the transmission housing. Drawbars and supports changed over the years from H and M to the Supers. Think the first H swingers were only 5/8 inch thick and the M 3/4 inch. M used 3/4 for a long time. Later on some tractors are thicker and the support opening wider. Or some early tractors have the later swinging drawbar attachment was added. Some thicker swing bars are installed by grinding the early opening bigger or end of drawbar down. Real early swinging drawbar supports had to be unbolted from the transmission to remove or install the drawbar. Swing pins are 1-1/8 dia. on a H and 1-1/4 on a M. Some pins longer than others depending on the support casting. H & M support castings won't interchange.
 
Using the wrong drawbar on your tractor will cause the PTO angles to be messed up when turning. Too close or too far, and the PTO knuckles will chatter when you go around corners.

Not a problem if you don't have any PTO equipment.

Exactly!! Just because it CAN be done does not mean it SHOULD be done. Lots of things will not be correct, and besides all of that, the swinging drawbar is to be used ONLY when pulling tillage equipment such as a disk harrow. All other equipment is to be hooked directly the horseshoe, except for PTO powered machines, and then you need the triangle shaped hitch plate bolted to the horseshoe. The triangle plate provides for the correct distance so the pto shaft will not bind up when making turns.
 
I would rather see the correct parts used also, but I just posted what I have found. Nobody told a lot of farmers what was correct, they made do with what they had. Wrong bars, welded up bars, extra bars welded together Extra iron welded or bolted on etc.

The information on what was correct was readily available to anyone that took the time to ask. All you had to do was visit the dealer OR consult the owners manual.

Today we have the internet, which provides ample opportunity to convey the incorrect information by allowing everyone to voice their opinion, with little regard to what is actual fact.
 
Not sure what your post means. If it means I lie about what I saw on tractors I sure don't like that. I may be mistaken sometimes but don't deliberately lie. All I said is what I found on tractors and the owners didn't care, or even want to find out what was correct.
Far as me finding stuff like that, thats a fact.
Did I recomend to do it? no.
Another fact is if the correct swinging drawbar is on the tractor, it and the drawbar plate you mention for PTO use is the same length to hitch pins.

After more thought maybe there's just a misunderstanding. I posted about the way drawbars I have found were rigged up and how it was done. Didn't mean to imply I was recommending any of them, but maybe it sounded that way. Although I have ground some support openings bigger to install the thicker drawbars. If its a misunderstanding thats okay by me, if not ?.

Geeze guys , don't get into a tissz over a lousy drawbar. Yes they will interchange. The way drawbars are worn out on most H and M's, exact angles laws are violated everday. After all that is why the pto has knuckle joints--To Flex.

I didn't mean for it to sound demeaning or anything. I too have seen a lot of jerry-rigged hitches on these old tractors, some of them are rather ingenious, and I'm sure all of them did work to some extent or other, but I feel that those of us who DO know the correct set-ups, (you, me, and several others) we need to do our best to convey what is correct.
