Old Three Point Disc / Harrow

[StuartIowa]

Anyone recognize this old three point disc? I cannot find a plate or any identifying marks except what is in the pictures. The big thing that stands out is this disc has two screw handles that adjust the angle (front and rear). It's about 6.5' - 7' and is very heavy for no bigger than it is. One of the disc part numbers did show up on the CHN website but I could not dig anything up. Would appreciate any feedback you can offer. Best!

Case. I can't tell you the model number.

Big thanks. Any guess on the general age or places I could dive deeper?

If anyone else has any advice or recommendations please keep them coming.

Thanks!

I would guess mid 50s to mid 60s, but can't say for sure.

I only see one crank, is there another one. I agree on Case.

Thank you. Yes, it's hard to see. They are stacked on top of each other. Here are some additional pictures. Hopefully you can see it better.

Thank you. Got it now.

Hi everyone... Thank you for the feedback so far. I messed with the disc today and gathered some better information. Front row (closest to the three point) is 7' wide with 12 discs, approximately 7" spacing. The discs are all about 17.5 to 17.75 (clearly worn down) with 1.5" +/- cupping. The rear row is approximately 8' wide with 12 discs, same 7" spacing. The rear discs are set with a 12"+/- gap in the middle. Same set up. The axel ends have a 1 5/8" square head on one end and a 1" threaded rod on the other. Three of the nuts are original square 1 1/2" and a replacement is a hex 1 5/8". All nuts are rusted tight with what appears to be a bendable lock washer behind them. I found a the following part numbers on most of the disc blades: H1272S, 1272S, H1272S 11PC, & 1115 VD "Rolled". I am sure I am going to need to cut off the nuts. Would like to have nuts, washers, and replacement discs standing by so I can repair all at once. Would appreciate any feedback (including axel diameter) if you have information to share. Thank you!

The numbers on the disc blades really don't mean much when it comes to identifying a model number on the disc. They're pretty generic across several models, even brands. How good of a torch do you have? Get the nuts red hot and they'll come off. If you do destroy one, any good sized implement dealer will have them, regardless of brand. All you need to know is the size, or take the remains or one with you. If you know the size, McMaster Carr will have them.

Thank you "rrlund"... appreciate the information. I was hoping the blades on it could tell me the axle diameter/size/type. If I knew the blade hole size, I could order replacements.

I have a crappy torch and I am not very good with one but could probably heat up the nuts well. To be honest, I figured I would ruin the axle or something else. But... I am glad you mentioned it because it may be my only shot at this point.

It was a bear but the impact finally won. If anyone is wondering, 1" square shaft with 1" NC threads. I'm still curious on the disc model number if anyone knows. Thanks for the advice/guidance!
