1850 3pt lower link length

[rhomium]

I have a 1965 1850 that I acquired that doesn't have any of the 3pt links. I've been looking around to find some lower links and I see there are two sizes. Ones that are 38" long or ones that are 40 1/2" long. Which ones would have the been standard option?

I can get a measurement tomorrow on my 1850. My measurements will be from center to center on the pin holes. Also, I'll take them on the outside of the arm if possible.............all depends on which is more accessible.

That would be great. Thanks for the help.

General configuration

Length of main lift arms. Approximately 35" pin to pin. Probably add another 4" for the casting around the pin.

Length of lift links. Approximately 23 1/2" pin to pin

Thickest part of the arm height wise. Approximately 4".

The main lift arm length is the original arm as it comes from the factory. The left side of the tractor has a lift ball I added some years ago. One of those weld on lift eye/ball thingies. Works fine BTW...........it's just a matter of weld prep, and attention to weld sequence.

The lift arms are obviously somewhere between a mild steel, and medium carbon steel...........or they wouldn't have taken the welds successfully. I did do an aggressive preheat, but I usually do on thicker stuff.

The drawbar is another matter entirely. I wouldn't dare weld on it, unless I had a junk one that I could test first. I've heard horror stories about welding drawbars. This might be a totally unwarranted fear, but better safe than sorry. When I rebuilt the drawbar system I left the wear grooves alone. Didn't attempt to fill them. I know they're a stress riser, but it is what it is. I redesigned/reinforced the hanger to place the load away from the wear grooves.

I couldn't tell you whether the drawbar is high carbon steel, or not.............. I do know that there's nothing welded to it, as it came from the factory. Sometimes, if you're not sure about a steel part.......take a look to see if there was any welding done on it during manufacture. The main lift arms have welded stuff on them, so I knew they were safe to weld.

I looked at AGCO parts books. They list both, but don't really say why there's a difference. I thought one might be cat 3 or use external cylinders, but can't see any difference but length. I keep forgetting to measure mine to see what they are. With no more differences in length than there is, I don't know if I'd be too concerned as long as I could find a matched pair.

Being a Cat II hitch on mine...........I'm assuming I have the non optional lift. Books show the Cat III as optional...........which I had a question about in another thread.

Only other dimensions that I might see as an issue might be the general shape of the lift arms, or how the anti sway blocks attach/work.

OK, my 1850 and 2-105 are sitting side by side. I measured both. The ones on the 1850 are 38, the 2-105 are 40 and a half. All the thicknesses are the same, all the curves look to be the same. The difference in length is at the bottom end between the hole at the bottom and the pins that go through the lift links that go up to the rock shaft arms. I'm back to using whatever you can find a pair of unless somebody knows a good reason why not.

I think that pretty much clinches it. If you're in the ballpark, you're probably golden. If we're both pin-to-pin................it's a good deal. Might be some different vendors on different production runs. Specs might not be mondo crazy. Close enough is close enough on a lot of stuff.

Good of you to make the effort. Probably a damn sight colder up there in the frigid North.

It was 34 today. Down right balmy. The wind is a bugger though. I had to go out and do chores anyway. Both tractors were sitting inside, so I enjoyed the warm temperatures inside out of the wind.

Great, thanks for the info guys. And thank you for taking the time to measure and take pics. Since the difference isn't that much, as mentioned I'll go with whichever size I can find a matching pair around here. Thanks again.
