| I was trying to identify the disc model of the one that was purchased with a 1952 CA. Is there a location for a part/model number on the disc/frame? I could find nothing. It is a wheeled type with single acting cylinder to raise/lower. The wheels measure 7' outer edge to outer edge of the rims. The front discs measure roughly 6.5' but some are bent and not both angled the same so hard to get a precise measurement. The rear disc sections are both not attached and located a few hundred feet away. I assume they would measure roughly 7' or 8'. |

I would think an 8' double gang disk would be a handful for a CA, no? Maybe I'm underestimating CA's? I suppose if a WD45 will do 12....anyways.... A lot of that equipment has a brass tag on the main frame near where it attaches to the tractor. Wouldn't surprise me if the tag is missing. If you take some photos, someone here might be able to give you a visual ID. ------------- German Shepherd dad 1957 Allis Chalmers WD45 #WD234847 1951 Allis Chalmers WD #WD88193 |

I used it a lot. It was no problem at all for the CA. We also always added a heavily weighted drag behind it to bust up clods a little better. Always made a nice clod-free perfect bed ready for the planter. I didn't think to get closeup pics while I was measuring for some dumb reason. I only have distance pics with it obscured by a lot of vegetation.

Get to work with your chainsaw and weed wacker. Normally there is no ID plate on most of the Allis Chalmers Discs I've seen. However I'd be guessing from your description it's a model 200 transport Disc. After getting it out and visible there might be clues to say it's something else. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits.

I've seen a lot of AC stiff where you could see where the tag WAS but is typically no longer. I'm thinking AC didn't have the best method of attaching tags to equipment when they did decide to tag it. Or maybe I am seeing remnants of a dealer tag? ------------- German Shepherd dad 1957 Allis Chalmers WD45 #WD234847 1951 Allis Chalmers WD #WD88193 |

Dealer decals can be most anywhere. AC tags were usually aluminum or steel, with rivets on the corners, in a central location. 50-80 years of dissimilar metals sitting in the weather, and they, too corrode away. They just don't make 'em like they usedta... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

It appears that I did take a picture of the disk in December. I was distracted reminiscing with my brother and thought I forgot. The hitch is designed for the drawbar. I've not found any online Allis Chalmers pics that look exactly like it. Especially the way the front end frame Vs forward into a solid frame extension in the center.

I just found an "Allis Chalmers" 411 disk that looks similar. And a Krause 207, 407, and 410 tandem disk.
It might be a Krause 207. That's the closest pic I've found so far. The 407 is similar but its either 10 or 12 foot. 207 is 8 foot (assuming it was identified correctly in the listing). I originally assumed it was AC because it was painted orange. There's zero indication that it ever had a tag located on the forward angled top brace (like the 207, right side of the picture). So maybe they were OEM to another brand. This had to be before around 1965 because it was old and rusty when I first saw/used it in the late 60s. If a Krause, it would seem to bode well for finding replacement parts :) AGCO parts for Disk Harrows does reference Krause disks 400 series from 405 through 412. Maybe it is a rebranded 400 series Krause. I've since found other Krause disks with no identifiable tag but with the Krause name stenciled along the rear cross member on the left and right side. Another had stenciling above the left tire on the frame. One on the front horizontal frame member and on the front of the V forward frame members in addition to the tag on the top of the V section. It looks like my particular design did not have Krause stenciled on the rear frame, only on the front V sections. A 409A model shows a rivet tag on the front of the forward V section near the joint. I find a Krause 406 with a 7 foot width that's very similar. https://www.purplewave.com/auction/180911/item/DB8318" rel="nofollow - Krause AI527 disk in Gardner, KS | Item DB8318 sold | Purple Wave At this point, without more pics various parts and some shaft diameter measurements, I don't think I can narrow it further. I would guess Krause 207 or 406. |

Here's a listing for the Krause 207: https://www.tractorhouse.com/listing/for-sale/226997259/1985-krause-207-disks-tillage-equipment" rel="nofollow - 1985 KRAUSE 207 For Sale in Seguin, Texas | TractorHouse.com Since that's from 1985, maybe older versions of Krause products just didn't include a riveted tag, or in another location??

I've decided that the disk is most likely a Dunham Lehr 'ground chief' of some vintage. Perhaps Krause made some of those. It is a krause-like design but with a Dunham Lehr style tongue section. The smallest was a GC-76 at 7.2" cutting width, then 78/7.4", 720/7.6", 86/8.3". ------------- 1952 CA13092 |

I think I'll be able to positively identify it with the below specs and some measurements.   ------------- 1952 CA13092 |

Of course, but I didn't know that at the beginning. ------------- 1952 CA13092 |

...but it is part of AGCO: https://www.agcopubs.com/agco_heritage" rel="nofollow - agcopubs.com/agco_heritage After additional measurements, it appears to be a Ground Chief GC-78 (or perhaps a later derivative). Original colors an off orange (frame, some say similar to flambeau red) and white (wheels/axle/arm) with perhaps some green on the scrapers. I might go PO #1 and silver as close enough (since I already have those). Cutting width: 7'4" Weight: 1395lbs Blades: 24 Blade Diameter: 18" Blade Spacing: 7-1/16" Just about the right size for a CA. Unfortunately, no site has reference to it for parts, even AGCO. AGCO has newer DL parts though. But this one has a square gang axle whereas available DL parts are all for round axles (given the hole size vs axle size, it may not matter). But similar parts are available for other square axle disks so probably just a matter of getting correct axle size hole and degree of "concavivity". Current disks are worn down to around 17.5" but I think most will clean up just fine. Don't think I'll bother with changing out for notched disks. Bearings are Timken, so should be no problem if I need bearings (those tested seem fine). Wish I could identify the location and design of any tag/markings. No pictures seem to show any markings at all. ------------- 1952 CA13092 |
