Snowblower PTO shaft

[BX2680MR]

So I ordered the wrong PTO drive shaft for my BX2750B snowblower thats mounted on a BX2751. Its about 15" too short. Before I order the wrong one again would someone have an idea the part # for the proper one. One thing that stands out is where it says "SERIAL NO. 2410735 AND UP" Im wondering if that has to do with some big change or some other adapter im missing. That picture Ive got of tape measure is from the mid pto shaft to the drive on this front mount snowblower.

It would really help if you Included:
1: Hitch model and serial number
2: Snowblower exact model# as there is eight versions and the serial number
3: Tractors exact model Number and Serial number as there are 3 versions of the BX2680

All these details matter for proper parts.

NOTE: My questions crossed with your edits, but I still need the other info to give you and exact answer.
And what is a BX2680MR, the MR is not a valid designation.
There are 7 different drive line setups depending on serial number.
You do know it's not a single shaft, it's 4 shafts to make the drive line.

One example:

All the mid-PTO shafts I can find are either 37-1/4" or 37-3/8" cap-to-cap.

How long is the shaft you ordered cap-to-cap? What part number was it?

Its 33". Sittin here looking at this french owners manual and when i gave this part number thats listed in the manual to the parts woman at the kubota dealer I made sure to ask the length and she said its also like 38" or somethin like that, not 48 anyway, which is what the measuring tape tells me. Ordering the wrong shaft was my own mess up as I look at the manual and realize its not even the right part number... But then to call to order with the right part # and it still not be nearly long enough makes me wonder wtf?

Trying to figure out how you're 15" too short as you're saying. The fixed length shaft is measured cap-to-cap but then you'd have to add in the length of the spring yoke on one side plus the length of the slip yoke on the other side. I do think you're about 4" too short, not 15".

To confirm, measure the shaft you received from end to end and see how that matches up with your tape measure picture. I'm willing to bet the ~37" shaft is what you need. BTW, I had a typo in my original reply. I said 38-3/8 when it should have been 37-3/8". There's an 1/8" difference between the two shaft lengths when looking at the various BX2751/BX2752 options.

The 70001-02186 shaft in your diagram is 37-1/4" from cap to cap.

Remember the driveline has to be "too short" at minimum length; the front of the driveline slips on first and then the rear has to clear the tractor PTO shaft so the driveline can extend and slide over the PTO shaft and be locked in.

Of course, but with the shaft clipped onto the pto its nowhere near the spline on the snowblower. I'll likely just take it to the machine shop and have them extend it to the proper length. Itll cost another couple hundred dollars and turn it into a $700 pto shaft. But atleast itll drive this snowblower i bought a week ago. Then onto the electric tilt and swivel that Im getting power to and arent operating. I guess I shoulda had him hook it onto his tractor and see everything working bfor i bought it. Its in nice shape, everything turns smoothly by hand, not a total wreck. Just need a pto shaft, and here I am a week later $4000 in and theres still alotta snow in the driveway.

Looks like you're about 8 inches short. I see 6 inches between the end of the slip yoke and the end of the splined shaft plus you'll want about 2 inches of spline engagement.

What's the total length of the splined shaft? I know those can vary quite a bit.
