serial # plate missing

I have a farmall super H. I think its 1954 year because of all the makings battery under the seat, 2-wide holes in grill, dics brakes,live Hyds. The date code castings is (6-15-Z)on serval areas. The punch stamp numbers on engine block is 33687. I want to know what serial #s I can put on the new tag thats missing? I have notice other super H,s the engine block numbers dont match with serial tag plate. But they do on regular H,s. any reply will help, Thanks

That engine went in the last month they built SH tractors, would be around 29000 number.
Could be mistaken on this name, but think its Pat H that collects SH serial numbers and is pretty good at telling what the serial would be. He did post here some, think he's on the IH collectors board some also.

I'm a little touchier than some about fabricating serial number plates, as some folks do some unscrupulous stuff with them. I'll hold my peace for those who have an original plate, but want to make up a new one for appearance's sake, as long as they keep the original plate. In your case, you apparently never had a plate and want one where one should be. And I'm even okay with that, but please don't make up a number.

There was apparently quite a bit of disparity between chassis and engine numbers on the SuperHs, as their serial numbers never got all the way up to 30000. A look at the Wisconsin archives, if I'm reading them right, shows your motor to have been made in the last month of production, October '54. The same tables for chassis numbers show production for October started with chassis #28694. Using some different records I would guess, Guy Fay's Data Book shows the last SuperH as #29285. The only thing that can be certain about your chassis number is that it started with "SH" followed by a grouping of five digits starting with a "2". We can't tell if the next digit should be an 8 or a 9. If you were to make up the reproduction plate to read FH 2XXXX, with Xs for the unknown digits, you will have a plate where one should be, the Xs will acknowledge that the original number is unknown and that the plate is a replacement.

I don't know if the plates in '54 still had the max no-load RPMs stamped into them or not.

The casting codes and features on the tractor pretty firmly establish it as a '54 SuperH, and as long as you use Xs for the unknown digits, you are not representing the tractor to be anything that it isn't.

Link below is to chassis numbers in the archives. There's a link on the left side of that page to '54 motor numbers.

Thanks for the info so far. This Pat H. person how do I contact? Thanks CP

shooting from the hip your serial number would"ve been approximately 28955 if your motor serial was 33687. Email is open, give me a few days to do some calcs and I"ll see if I can narrow it down any closer. I own SH 28703 with a motor 33390, just a few hundred away from yours.What state do you live in?

I'am real concern about the correct serial number too. The history of this tractor I know so far I purchase in SD this summer it had two previous owners. 1st owner bought new orignally the 2nd owner had it about 15 years. You can tell the riverts been chisel off. Prevoius people have looked at tractor before me. Thanks for the reply CP

I Live in the lovely cold weather state of North Dakota. Thanks agian

Ihave # 29093 with engine # 33869.

Dutchman, and others, I have a stamping machine that I bought at a flea market for $5. I have had people tell me they go for $1000 or better new. I have not done serial # plates before, but this machine has a ratcheting table with guides so you can make the #'s straight in line and evenly spaced. Plus you can set how much pressure you place on each letter.

I use it to make dog collar ID plates.

I could stamp the #'s in for you just for the fun of it. This might be overkill, the factory probably had some kid doing it freehand

My experience with the numbers varies.

On the motors they do usually look to be hand-stamped. They move up and down a little, some a little crooked and different depths.

On the other hand, the serial # plates tend to be straight and look as if they're done with a rig like yours. An exception to that though is my BN. The Model and serial # are all straight and neat and evenly struck, but the max engine speed, 1540 is a little messy. It looks like two two-digit punches, 15 and 40 with a little bit of space between them. The 15 is slightly smaller type than the 40 and looks like it was hit a little harder.

Dutchman, How about trying to contact original owner and see if they might have the book or something they might have written the serial # on. I have bought many tractors that came with original manuals and written in the front or back were the serial # of the machine.Worth a shot.

Listed below are the engine numbers and serial tag numbers on my SH's.

Engine Serial Tag. Block casting date
22310 19574 10-5-Y
22369 19634 10-6-Y
23221 20471 10-20-Y
24403 21636 12-8-Y


As you can see the engine numbers increase faster than the serial tag number do. In this instance, the serial tag #'s increased by 2057 units while the engine #'s increased by 2093.

Hope this helps. Marv

Thanks for the suggestion although I asked the same question. I was told the 1st owner only lived 10 miles. But he has passed away and that farmsite gone. Thanks for the info.

looks like the number would have been SH 28954 J
I"m about 95% certain, sorry best I can do.Hope that helps you some and hope you have a Merry Christmas.

Hi Pat. Thanks for Number info. Although since I do not have the orignal plate. I think I will make a new tag with the last number something different like 28954 MS?. Then if I ever sell it I'll call it the mystery tractor maybe it worth more ha ha. One more question, what is the J at the end stand for and is it on all supers?

Thanks for all the hard work finding the numbers.

The J stands for Rockford clutch, think thats all they used since the late "40s sometime. CNKS maybe will see this post and add the correct date for the start of the rockford clutch. Every super H I have ever seen has a J suffix

The J means the tractor was equipped with a Rockford clutch. I have never seen a Super H that did not have a Rockford clutch (and a J at the end of the serial number). By the way, you can trust Pat on nailing your serial number. He keeps very strict records of all SH tractors he comes across and can correlate the relationship between the engine numbers and the chassis numbers - since he has records on both sides of virtually any number. mike (SH 20856 J).
