I known you long enough to know you knew, just forgot. :beerchug:

Yeah...... It happens to me more and more. :angry:
Too much on the brain. :BlahBlah:

Keeping in mind that I'm a rookie here...could I just swap the hydro units? Or are they too different? That would solve the tapping of the shaft and I could replace that gasket that I keep reading leaks often. There's something up with the controls on the 1872, all the parts are there but one of the parts is flopping around. I haven't dug in enough to see if it's just a loose bolt or something yet.

Yes, I really like the look and the metal parts are all in great shape except for the fender has a minor bend.

The 1872 doesn't have a viable driveshaft, missing PTO, muffler and several small parts like hood hinges. The deck is a little beat up, but repairable, and is missing the front wheel assemblies as well as some minor hanging hardware. Motor is good.
The 1882 has no usable plastic body parts, fender is trashed with bends, dents and rust. Deck is all there, needs cleaned up and painted. Motor is unknown, they guy said the "magneto" was bad, sparkplug wire is missing on one side.
I might use what I need from it and store the rest of the 1882 for some future project...I do have this 2185...

Without looking, I can't recall if the control plate was the same. The swash plate arm is.... but I think the control arm is different. I think the parts book calls it a swashplate. (Not really what it is, but I think that is what it is called.) Go to cubcadet.com and look up the two machines and compare. You can do it just like I can. Or park them side by side and compare. Sorry for the above confusion. The rear ends themselves will interchange, yes. But some of the control plates may not.

The CV shaft conversion is a good one to do. I'm sure you are like a lot of SGT owners though. Probably just going to use it as an overgrown lawn mower, so other than adding some rear end braces, and getting it working good, not a lot you need to worry about as far as making it "stronger". Probably would have been a lot easier if you had bought two "like" tractors, and bought a CV shaft by itself if you wanted to do that conversion. Also a lot easier for you, and us, if you would "dig in" and find our exactly what you have, and what you need to fix. Guessing usually just makes things worse. :beerchug:

Mine don't have a roll pin. Just the splined shaft.

Todd, the parts book lists a spirol pin in the description that goes with call out number 7. Perhaps some have been removed, or broke out... or maybe just didn't use it. I have an 1872 down in the barn, but honestly never looked at it, and I haven't had the shaft out of one in at least 3 years.... I'm starting to forget.

That was the plan, then I found the 1882 for the price of a good used shaft...

Can't beat that I guess.
How about some pics of these two tractors?

:TTWWP:

Todd

Your tractor should have a roll pin to hold the "Arm" number 7 on the shaft of the pump. Maybe that's part of the reason your shaft came out and trashed a bunch of stuff.:bigthink:
