I posted in classifieds just wondering how hard it will be to find a complete AC hitch like in the pic? I'm wanting to remove my aftermarket hitch that I bought about 5yrs ago.

Any particular reason you are replacing the aftermarket hitch? Just because it isn't authentic Allis or another reason? |

| Basically yes not authentic and I'm trying to get more snap coupler equipment to restore with the tractor. |

| I stumbled upon mine by a freak of nature and havent found another one since,---so depending on location, they could be kinda hard to find. I would take an aftermarket over the snap coupler type anytime! thanks; ac fleet |

| Thanks. Been a project for awhile. Complete engine rebuild. Next thing is to rebuild finals and brakes(already have parts). Also looking for a 4 bolt wide front to rebuild. It's a '57 originally narrow front. Grandpa put on the 3 bolt wide front. Looking around for front stack weights as well. |

It should have been bolted to the drawbar...I had one just like it on a D17. Just remove the pull arms, remove anti-sway, remove drawbar and you are ready for sc equipment. ------------- ALLIS EXPRESS! This year: |

| The aftermarket style hitch I have doesn't bolt to drawbar. I don't even have to have drawbar on to use it. I have drawbar off right now because I had a plow on it yesterday. |

Yep, that hitch is the "newstyle" that we sell. Bolts to differential, not drawbar. The wishbone style has been continued by the manufacturer and the originals (Like Eldon's) are hard to find. For straight 3 point work, the one you have is a LOT better, but I have customers that have SC implements and want the quick style. Best of luck, and Eldon is not out of line on price. ------------- Owner of http://www.OKtractor.com" rel="nofollow - OKtractor.com PM for an instant response on parts. Open M-F 9-6 Central.

I agree the aftermarket are the closest thing to factory 3pt you will get. I didn't know those wishbone style were rare. I always scorned them for being rather crude compared to the heavy-duty aftermarket style. But...for someone with a lot of SC implements and not many 3pt, that hitch does make the most sense, as far as ease of hitching and unhitching. A buddy of mine has a couple of them, and one was on his D17 Series II LPG he sold to a guy in Nebraska.

They aren't real rare, but ones in good shape are. Years ago I sold a lot of copies of the 3pt adapter manuals to guys on this forum. There are a number of different styles, some are made to attach to the implement and stay with it, some stay with the tractor. Then there are a couple of different sizes for the smaller tractors and the larger ones. ------------- ALLIS EXPRESS! This year: |

| Only real use I have for the 3pt hitch is a boom pole. I have a snap coupler plow and blade. I do have a 6ft 3pt Ford disk but I want to get rid of it and get a snap coupler disk or a wheeled disk. |

| About 15 years ago there was a fella northwest of Hiawatha, KS making those adapters that were based on the AC pattern. Don't know if there might be some of them out there yet. I'm thinking he was selling them in the $250 range back then. Do you have a local welding shop that could fabricate something? |

How does someone use the SC 3pt adapter with PTO driven implements such as 3pt rotary or sickle mowers? Would you remove the 3rd link from the adapter and use one mounted off of the rocker shaft? ------------- Ben (Eastern Washington) WD45 190XT SIII |

The AC version as shown was actual presented as a device for adapting 3 point implements to snap coupler, rather than adapting the tractor to 3 point. However there was an available top link bracket that clamped around the center of the rock (lift) shaft and different brackets for the lower arms - either sway chains or a more restrictive stabilizer device. We put one of the AC adapters on our CA back in the 60s (after first adapting the pin hitch to Snap-Coupler). Steiner Tractor sells (or at least used to) an aftermarket version of the AC adaptor - or at least the wishbone part for the lower lift arms. Their bracket for the top link is just a piece of steel belt into a "C" shape, that tends to slid back and forth along the rock shaft. For my D12, I bought the Steiner Tractor device for the lower lift arm "wishbone" and had the top link bracket and stabilizer device fabricated based on the AC design. |

Pics from the manual. The ones pictured above are the models that go with the tractor as they have the swivel balls in the arms where they attach to the implement. The adaptors that stay with the implement do not have the swivel ends, just a hole. http://s29.photobucket.com/user/ejons/media/Implements/3ptqdqpter.jpg.html" rel="nofollow">  ------------- ALLIS EXPRESS!

When using PTO driven equipment such as a bush hog, in addition to the rocker shaft mounted top link bracket, the use of the factory anti-sway "stabilizer" shown in the first drawing here would be nice to have. I have two A-C 3-PHs but the one with the top-link to the rocker shaft did not come with this piece. As a matter of fact, I've never seen one "in person". The "sway chains" shown in the second drawing are there for keeping the bars from swinging out and hitting the tires and might work with a set of plows but would never stand up for controlling the sway on a heavy piece of equipment like a bush hog, especially in hilly terrain.

| be careful not to have the sway chains to tight or yuo will bend the arms in with a heavey load , i had mine adjusted to take all the sway out with a scraper. hooked to it that would be with the arms about straight out when scraper is down , then hooked to another piece of equipment were the arms had to go all the way down and the sway chains were to short and pulled both arms in right were the chains mount . that top picture that brian has there looks like that would work the best were it holds to set width and pivots in two places to go longer and shorter for travell up and down on the arms |

| We had the AC stabilizer on our CA when I was a kid. I had one fabricated for use with the "wishbone" lower lift arms from Steiner on my D12. I have the plans for it filed away somewhere, along with the top link bracket I had machined. |

I have D17 Series IV I wish I had the after market combination 3 point/draw bar. Dad & I would take the 3 point hitch off in the spring and put the draw bar on to pull the bush hog. Then in the fall, switch back to 3 point to haul large round bail hay to cattle. The snap couplers have been taken off, but we have them. Grandpa made adapters to replace snap couplers. I hope he didn't cut and weld. I think it can be put back to original. I don't know which version I have. It's on a Series IV. Both the draw bar and 3 point (looks like the wish bone) latch into a hook under bottom of the tractor. I can email pics and prolly consider trade. My father is 84 and wanting to sell the farm and move to town. I have a neuromuscular disease that's causing me to loose muscle. So I would like to sell this D17 (gas) and buy a big zero turn lawn mower. That or a belly mower for the D17. We're mowing 3-4 acres of lawn every week all summer with D17 and bush hog. ------------- AllisChalmers D17 Series IV. Want to learn common faults & repairs. Maybe selling farm and selling it.

don't know if you can use this idea but,'Troy' here had a loader/no PS so I built a snap-coupler 'carry-all' for it to replace the loader as I move 'skids of stuff'. works great. I welded a 2" receiver onto the carry all. I simple put in a sleeve with ball to move trailers,a balless one to use as a drawbar. maybe it's an option ??

The previous posted pic of Series IV 3 point. I had never seen the safety chains. Guess grandpa took them off. But I remember seeing orange steel arms that dad didn't know what they went to. Now I know they are the safety chain brackets. There somewhere in the barn too. My grandpa died when I was 7. Dad already had the D17 at our farm. Before the auction at grandpa's, dad went through every box, cabinet, tool crib, all over getting every Allis part he thought went with our D17. Grandpa had an Oliver Hart Parr and couple Row Crop 77's. We just sold the original steel wheels to someone doing at Hart Parr restoration a few years ago. If the guy is on here or someone on here knows him. I lost contact info and would like to get in touch again. My dad would like to see the restored Hart Parr. They buyer had a family member or friend that drove semi on a route hauling glass panels to Florida. He stopped at our farm outside Metropolis IL to pick the steel wheels up. If your on here, contact me please. ------------- AllisChalmers D17 Series IV. Want to learn common faults & repairs. Maybe selling farm and selling it. Maybe looking for belly mower for it. |

Somewhat of an aside point that may not be immediately relevant to the OP's interest, it may be a historical tidbit worth knowing: These 'adapters' were manufactured under some 'legally challenged' circumstances. Realize that Harry Ferguson had a substantial honeycomb of patents for his invention of the 3-point hitch. During the timeframe that he was in business partnership with Henry Ford, the patents Harry held, were well protected by Ford's legal army. Once that partnership fell apart, it left Harry's patents in a position of weakness, and also left Henry in somewhat of a pickle... Henry was, by virtue of their partnership, the largest manufacturer of the 3 point hitch, and practically his entire implement offering relied on the design. While he didn't 'own' the patent, his partnership granted him de-facto 'liscence' to manufacture them, and there was a pretty massive legal question as to wether Henry owed Harry 'royalties' for continuing to produce the 3-point. Well, at the same time, there were gobs and gobs of other marques that used some 'other' design of lifting attachment, and the design and operation of those lifting attachments in many cases, had been legally attacked by Henry and Harry for violations of patent. It was not unusual for someone to think up every and any idea they could, wether practical, feasible, viable, or not, and file a patent FOR it... with NO intention of ever actually 'doing' it... specifically so that anything a competetor DID, would be at risk of legal action for patent infringement. Well, when Harry and Henry had their falling out, the 3-point hitch patent enforcement became 'weak'... but still, no tractor manfacturer would offer THEIR tractor with a 3-point hitch... it was too 'risky'. But making an adapter managed to either 'skirt' the original patent just enough to get by, or would constitute a low enough value so that the manufacturer wouldn't be making enough profit for it to be worthy of attack by the patent-holder's legal-beagles. Plus... Henry and Harry's legal-beagles were kinda busy fighting amongst themselves. Now, prior to the falling-out, Henry and Harry had a certain vested interest in the presence of 3-point implement manufacturers... because those implements made THEIR TRACTORS more desireable... and as implement manufacturers, Henry and Harry knew that if other tractors had 3-point hitches, that they could sell more of their OWN implements... And they would certainly be interested in doing so, but not at the expense of lost business on their own part of the tractor pie. From that perspective, it meant that what they BOTH had to do (before AND after) was to allow just enough license of others to make their stuff desireable, but not allow others to use something that was quite-as-good as a proper 3-point. So it's an interesting paradox, that was ultimately smashed by fate. The end lesson, though... is that amidst all the good things they did, there were aspects of HOW they did things, that while legally right, and ethically exempt, were moreally less than pure. The adapter was something that got through the grey area... not just for AC lovers, but every other outfit, both major, minor, and farm-made. ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem.
