I am hoping someone can help me identify the model # of a couple IH disks I have. They have a rope trip on the tounge and a tower like thing in the back to adjust the downslope of the back gang. I am not sure how else to describe it, or what to look for. All I know is they must be pretty common, I have 2 and know of at least one, mebbe 2 more around here. Width is about 7' or so. I pulled as many casting numbers as I could(if they don't have a description, they are frame parts):
DH449-Spool
DH476-Bearing housing
DH4X7, might be 477, might be 417, or something else--my handwriting stinks(Tounge slider thingie)
DH442
DH435
DH444
DH440
DH447

If anyone can help me ID this disk, or perhaps find a manual for it, I would much appreciate it. I am going to put the two I have together and make one decent one out of them(one has a broken hitch, the other a couple bad blades and missing some scrapers).

Mike

None of the part numbers you mention are IHC numbers for tillage implements of that time period. The numbers would have a P, PA, PB, or PO prefix. By the time wheel disk came about the numbers would have been 6 digets and then a R1, R2, R91 etc.

Thanks. Today I was going through my stack of old manuals, many of which were from my grandads estate. I found the manual, and the disk is an OLIVER!! Uhhhh....

I guess it would have been more difficult than I thought. Don't worry about it, once the paint gets off these old machines and you remember that certain make of equipment grandad used. Some of those old grandads were kind of careful with money so sometimes tricked us going to a different color.

By the way I also have the book on Oliver equipment. My son has the Oliver book right now. I expect him here sometime in next two weeks. The IH No. 37 was first built in 1961, I know, I couldn't believe that either. Cockshutt and Oliver were about 4 years ahead on the wheel controlled disc.

FM: I looked at this last evening, and there is quite a number of them. It isn't going to be easy, but what the h#$%, nothing worth doing is easy. I am going to ask some questions first. Does it look like either front or rear blades were notch type? Do you pull rope and move tractor back to increase angle of gangs? Foreward to decrease angle? Is there an upright type of lever at center of each gang that a rope to tractor hooks to? This is in addition to rope on hitch, total 5 ropes to tractor. That one must be out of the dirty thirties and they thought guy might want to hang himself. Is there diagnol pulling beams betweem front and rear gangs? If you were to put a date on this disc, what decade would call it? What is the spacing between discs?

The more I look at this it has to be about 5-6 different discs built between 1930 and 1960. The models are 9A, 9B, 9BA, 10A and 10B. All the discs prior to 1930 had the gang angle changed by notched lever. Some good arm mussels developed on those. If you get back to me with answers to those questions, I think we can nail it. I'll do a bit more reading to see if I missed something.

The disks are all smooth edged. To adjust the angle to dig deeper(more of an angle, instead of straight accross), you pull the rope and the toungue slides as you pull up. To adjust it shallower(less of an angle, towards straight accross), you back up. As far as when I think it was made, I think it was probably mid 40s, or possibly late 30s but I don't think so. They introduced wheel disks in the 50s, I think so that is too new:-) Thanks for your help.

The model numbers of discs I gave you were in the order they were produced. The first 9A was built in 1929. The last 10B was built in 1960. That has nothing to do with when the first wheel controll was built. I told you if you answered my questions I could ID that disc and I will if your interested. I could also tell you when the first NO. 37 wheel controlled disc was built, because you don't know.
