Disc Harrow Identification

I am trying to figure out what the make and model is of this offset disc harrow. It is 10 foot wide, axels are about 5 foot each 1 inch square, discs are 16 diameter. I believe it is CASE IH but not sure
and no idea what the model would be.

The main reason I am asking is one of the axle nuts fell off and I need to replace it. I cant seem to find the correct square nut. It is 1 inch thick, the sides are ~ 1 21/32 inch wide and a ~1 inch
diameter. Threads look to be 8 per inch.

Any help locating the correct nut would be great.

remove the nut off the other side and take it with you to any fastener dealer. its a disc, unless you are pulling harrows behind then you are doing both.
 
That disk is a Kewannee.The nut would be a common 1inch,8TPI hex nut.Abailable at any hardware store.Doesmt need to be a square one.Shoup Manufactureing sells the double tapered roller bearings that your disk uses.Last I bought(15years ago)were $75.oo each.
 
guess u guys call them that. all we call them is a tandem disc. harrows is a separate piece of equipment. or else we pull harrows behind the disc.
 
Looks like 1 1/8 UNC is the size.
Parts catalog for a 37 Disk-Harrow says part number 220 089. Picture in the catalog is almost the same as your machine.
