Left lift rod too long?

My New Holland dealer is pretty far away, and you guys are so close, so I hope you don't mind my asking: why is this lift rod so long (I'm just curious), and what do I have to buy to correct it?

It is (apparently) New Holland part # 83924897, made in Canada. In an earlier discussion, Need length of 3-point lift rod, we decided the correct length (hole-to-hole) is about 20 1/4", while this one isabout 23" (unless I misunderstand what was being discussed and measured there).

I see no way of shortening this one -- the two parts are already screwed together all the way, as far as I can tell (but it's also rusted tight). Is this not a category I part? Do they come in different lengths? Is it too long because it was made in Canada ? ;)

I know I can replace the whole thing, but would it be possible just to replace the top (yoke) or the bottom (fork) to get the correct length?

And if I do replace the whole thing, any idea what kind of person might want a long one? :)

Thanks, as always.

But maybe I can get a bottom fork like the right-hand one to use on the left side; that might work. Thanks for the suggestion.

You CAN USE the adjustable lift rod in the lefthand position if you want to. Normally, the R/H liftrod is adjustable for plowing adjustment because the R/H wheels usually travel in the bottom of the plow furrow AND you want your plowshare to cut the soil with a vertical kurf.

I see the ringmark on the shaft which is normally adjusted to the end of the outer black sleeve, this should make your lift arm the correct length. You should be able to adjust your liftarm by screwing it up into the outer sleeve even without the gearbox. Normally, you have about +/- 4" of gearbox adjustment range..... ...Dell

Here's a view from a different angle (looking from what would be the front/bottom of the rod when installed), along with a view of the right-side adjustable one still on the tractor (which may or may not be its true counterpart):

I suppose the left one could have originally been an adjustable one, but does that mean the crank would have been at the bottom? The fork is just wide enough to attach to the lift arm, so I don't think it was made to go the other way.

And the length, if I were to screw it in to the ringmark, would still be about 2 1/2" too long; similarly the right one, when cranked to its shortest position, is still just a little over 20 1/4" long hole to hole. The other reason I think they're too long is my lift arms practically drag on the ground (1/4" clearance from a flat floor) when lowered all the way, but I guess something else could be adjusted wrong.

So, is the 20 1/4" hole-to-hole length previously measured by a couple of people correct? And, if so, what were these longer ones (or just the right one, if the left one was a hodge-podge of leftover parts) made for? (And does anybody want them???)

Thanks again!
