Blades & Bearings for IH 122 Disk Harrow

RTR

Well-known Member
Guys, I have an IH 122 Disk Harrow that I need to repair. It has 18 inch notched blades and one of them has broken. While I am replacing the blade, I thought I would replace the 2 bearings on that shaft.

I am having EXTREME difficulty finding the 18 inch notched blade for it. Any help or suggestions??

What about the bearings? I have located some at Agri-Supply online, but they look slightly different (square not round case).
 

Here are some pictures of my disk harrow......

Try Shoup or Sloan. If you find them you might want to buy more than one. You may need some more very soon.
 

Shoup doesn't have them and Sloan only has 20 inch and 22 inch in the Smooth blade. They don't have any notched flat center blades.....mustless the 18 inch.
 
agri supply does show an 18 inch notched bladee with a 1 inch square hole, 1 3/4 concavity. not sure if they would fit your axle. another thought, if you have the clearance, can you go to a 20 inch blade? from your pictures, it looks like you may be able to go with a bigger blade.
 
I could possibly use a 20 inch blade, but I would hate to have all 18 inch (worn down to 17 1/2 inches), then a new 20 inch in the middle. How do you think it would look/operate?

The blade that it takes is a "Flat Center Blade", which is what Case/IH disk harrows used. I haven't taken mine apart to see if that is what they in fact are, but from research that is what it seems to have. Agri-Supply doesn't seem to have the Flat Center Blade in an 18 inch notched size.
 
i wouldnt run just one 20. you may need to bite the bullet and go to all 20's. last resort would be to get an 18 smooth and cut notches in it with a plasma cutter. you would loose some temper on the blade tho.
 
You have a mish mash of spacers in there. You don't ne flat center discs. The first thing you need are bearings, If you don't get them that disc is scrap.
 
Case-IH dealer SHOULD still have a 18 inch flat center notched blade available. The bearing and the flanges should be available yet, too. I think that the riveted square bearing assembly will work on this disc. I had a 370 with bearings like these and switched them to the 1pc. bearing.

Thanks so much AG. Our only dealer in the state has dropped Case/IH back in Feburary and now C&G has dropped them. I'm not sure who I will choose to call, but I guess I just assumed they weren't offered anymore.
 
Get the spacers out and look at them. Are they solid out to the very end (flat)? Or are they somewhat hollowed out. If they are not flat like a solid rod then they will work with regular discs.

Wiese and Ingersoll show 18 inch notched flat-center blades available. You'll have to find a dealer who handles either or both of them, though.

As far as C&G, it's sad to see them go.

It's happening locally here, too: Longtime, good dealers that don't move massive amounts of new machinery, have 2 or less locations, and don't have fancy new buildings are going away, and it's not the dealer's choice. It's gonna be really hard to find a local dealer here in five years with any interest in selling parts for or servicing the pre-85 stuff.

I don't think any dealer can ever move enough new machinery, have a fancy enough building, or have enough dealerships in their conglomerate to please CIH's momma FIAT, and decades of quality representation of a company and it's predecessors means next to nothing to them.

Thanks again AG. Do they not sell to the public? I will have to do some research to see who sells them.

Yeah, it seems like something will have to give with CIH (CNH). You're probably very much right about the parts availability and dealer-intrest in pre 1985 stuff. Maybe I should go around and try to buy out the stock of the "old dealers", and just sell parts for old IH Farmall tractors and use the parts for myself in restorations. Someone will have to carry on the parts....
 
Here we go again just type in disc blades then it will come up disc blades for agriculture and there they are on the front page 18in notched blades. I just looked them up

Yes, the standard notched 18 in. blades are easier to find, but it is the "Flat Center" ones I am having trouble with. Will call a dealership tomorrow to see what they say.
 
I just replaced two of the bearings on my 120 disk this spring, the one piece bearing with the square flange will work in place of the round flanges, and is MUCH cheaper. You will also need different bolts because they use a smaller size bolt for the round flanges.

Thanks for that Info about the bolts. By chance do you know what size you had to use. Carriage or standard ?

What about the bearings? I have located some at Agri-Supply online, but they look slightly different (square not round case).

Did you ever find the 18"notched discs, bearings, spacers, etc for a rebuild? I am rebuilding my IH 122, which was in much worse shape than yours, and I found all the necessary parts.

I remember finding some parts but it was tough finding the correct "flare center" ones with notches. Please share where you found all of your parts.

I got the 18" notched disc blades at Agrisupply, part # 80337. I don't know what "flare center" is. These are standard concave and they fit fine.
I got the spool at Sloane Express. They have a big selection and best price.
I got all the bearings at H&R Agri-Power, www.hragripower.com. They bought my IH dealer and they had plenty in stock. The bearing housing is not quite the exact same so I had to buy some 1/2" mounting bolts because the holes are 1/2" and there was some slop when mounted. Also way better price than anywhere else.
Hope this helps.

"Flare center" should have been typed as "flat center". Sorry it was a typo by my cell phone that wasn't caught until after I sent the post. Those style blades are found only in case/IH units and I've been told by many that those types of blades are required for it to work properly. If i recall, I believe I found the "correct" ones from Shoup Manufacturing via special order.
Hope this helps.
