Farmall 100 plow question

Tue Jul 24, 2012 1:16 pm

Plow beam size crop.jpg

I am trying to find out what the model of this plow is and how to make adjustments to it. Possibly a manual? I plan to use this many years and will need to know the ins and outs and also be able to source parts like shares, etc. more pictures to follow.

Probably an A-193. Hard to tell anything from your pictures.

What should be in the pictures? I thought the casting numbers would be the ticket.

That looks like a Super A one bottom plow looks to be a 14 inch or 16 inch moldboard not real sure tho

It's a 16 inch, butt I'm trying to find out the model number and get my hands on a manual. What was the stock plow for the 100? Is there a better plow for it ? I also am trying to find out what carburetor is on my 100 and get a manual for it as well because I'm not familiar with it and the adjustments.

The casting numbers would help if I could read them. At the same time, they are in so close I can only guess what the part is.

1) I think it is the beam. The beam for an A-193 (and some variations) is 512504R1. You can check it.
2) Plow bottom and the curved part of the beam. Any bottom IH made could be put on any plow they made. Even if I could ID the bottom, it doesn't help ID the plow. The section of the beam in the picture is just a simple curve, identical to probably dozens of plow models. The only tell in the picture is the chain very far back on the beam. Few models have a chain that far back.
3) Is the number O 3068? I scanned 4 large parts catalogs and found that number is the moldboard on a BBA bottom. Giving us the size of the bottom would help too. I guessed the part may have been the moldboard, but sure couldn't say for sure until I found the number (if that is the number). Even so, as I already said, IDing the bottom is no clue as to the model of the plow.

In brief, don't crop the pictures down to where you can't tell what the part is. Include a picture of the whole plow so we can see the unique parts. Show pictures of the part numbers but read them for us. A straight-on picture of a part number takes out all the relief that you have when the part is right in front of you.

Ok I will do my best, the top picture is the beam it has "12504R1" there are impressions before this but I can't make them out, but they don't look like numbers more like squares. it's a 16 inch plow. The last picture is the back of the moldboard.

Also the number you have is correct on the mold board.

Re: Farmall 100 plow question

OK. It is an A-193, later IDed as simply 193. It has a 16" BBA bottom. The illegible stamp in front of the part of the number you can read has to be a 5. There may be a mal-formed IH in front of the 5.

Thanks! I really appreciate the help. I'm new to all this so I really am thankful for your time and knowledge.

Also, I have been searching around and have found out that this is a "super chief" bottom? And you told me that it had a "bba" mold board, from what I have found, that is a general purpose? What does"bba" mean? Also, my land side has a one piece molded look, but most pictures I see have a bolt on heel. My land side thickens up in back, but doesn't have a replaceable section, is it for a specific purpose? Can I order new shares/shins for this plow?

It is not a Super Chief bottom it is a BBA bottom. That bottom was built from '37 to '61. It is a "general-purpose moldboard adapted to stubble and tame hay sod plowing." The landside of that bottom does not have a replaceable heel, even though other bottoms do. Replacement parts for that bottom will probably be a challenge.
