Drawbar Help Please

[Mark Slavens]

Need pics of how the drawbar attaches to my 1947 Farmall A. I ordered a new one and the forward-most holes on the final drive castings are not threaded to accept the 1/2" bolts that the manuals call for.
I am stumped !!!!!

They were when new now its hard to tell just what size they mite be. You will probably need to drill new holes in the drawbar.

Depending on how big the holes are now, you may be able to do some helicoil type repair. Seems odd that both sides are damaged. You don't have Super A housings do you?

post a picture of the one you have, there are a couple of versions,i got an original one and it mounts to same bolts as the rear cultivator they are 5/8 unless I'm mistaken

These are pictures I use when putting the drawbar back on mine after cultivating the garden. Who knows if mine has all of the right pieces, but it works. The pulley frame for he woods mower is on there, too.

Whoa! Time out! The drawbar normal does NOT bolt directly to the final drives. Normally there are threaded studs that install in the final drive, then a pair od drawbar plates bolt to those studs, and finally the drawbar hinges on the sold studs that protrude from the plates.

Doe you have the drawbar plates?

Whoa! Red flag on Claven2's post. It is a detail description of the Super A drawbar. Notjustair's pictures are of an A drawbar. It is a little hard to see due to the other brackets that happen to be on the tractor. The front bolts that are the subject of the original question are obscured by the mower bracket brace.

Claven2, I jumped to that conclusion too, having a SA, but I checked the on-line parts manual for the A, and yes, the A drawbar bolts directly to the final drives.

Mark Slaven, it's possible that the 5/8-11 thread bolt holes have severely rusted, or already re drilled and tapped the holes, or as suggested above that someone put SA final drives on your tractor in which case, the threads should be 3/4-10 (NC) in the holes. Helicoils may work, or you may need to get creative, depending on how close to original you need to have it.

Ya, I didn't catch that it might be the earlier A arrangement. It would be helpful if the OP provided pics of the DB and the FD arrangement he is trying to connect to?

Gents - the manual calls for 5/8" x 3" NF bolts, with lock washers and nuts in the rear holes. No problem. The front holes take just 1/2" bolts. That is where the problem is. The holes have been enlarged and are without threads. I'm leaning towards helicoils. I believe the final drives are not Super A. How do I tell ?

yep (had to walk out and look at my 2 A's)
Big thru bolt at the very rear.
smaller square head bolt going thru one of the height adjusting holes.
If the helicoil doesn't work out....
farmer-do what ya gotta-fix....
The big nut and bolt hold it, the front just locates the height.
Put the big bolt in, put the drawbar height/level where you want it, see which hole lines up.
weld a nut over that hole on the inside of the drawbar flange.
Thread a good bolt into it, thru the flange and into the finals hole. (homemade pin sorta) Other makes, models, use the one bolt, 1 pin arrangement.

advice...track down the front crosspiece too, so you can have the swinging drawbar setup. much stronger and distributes the load better.

(quoted from post at 05:44:48 10/26/15) I believe the final drives are not Super A. How do I tell ?

he original A housings:
Rear bolt has a through hole, bolt inserts from the outer side, nut goes on the inside.
Forward bolt has a blind hole, bolt screws in from the inside.
Front of housing has another through hole, identical to the rear, for attaching the swinging drawbar cross bar.
Part number should be 6827D, 6827DA, 6827DB, or 9800D (left) and 6828D, 6828DA, 6828DB, or 9801D (right).

Super A housings:
Both attachment points for the drawbar are blind holes.
Both holes are the same size.
They normally have studs and nuts for countersunk holes, but studs could have been replaced with taper-head bolts.
The front of the housing has 2 more blind holes with studs that allow the drawbar to be mounted at the forward end of the housing (for reversing drawbar to mount plow).
Part numbers will either be a "D" number larger than the ones listed above or a six digit number followed by "R" and another digit.

FWIW, some of the holes in the FD for the Super A are not blind, but go all the way through. They are threaded though.

Thanks to all !!! This site is sooooo valuable !!!!!
