FWIW The mag 20 that I put in my 782 has an 1 1/8" crank, the same as the KT-17 that I replaced. The mag shaft is longer and had to use a spacer on the outside of the PTO. (this mag was out of a Huskee GT)

Here's what I would do.

Step 1. Start the engine and let it run at about 1000rpm.

Step 2. Take a grinder to the crankshaft until it's pretty close to the right size.

Step 3. Leave the engine running and finish sizing the crank with a file.

Step 4. Install new crank seal.

Step 5. Install PTO.

From serial number:756,300 to 799,999 all 1872 Cub Cadet Magnum 18 engine have 1-1/8" crankshaft, Kohler number 52 014 66-S

The serial number of the 1872 you sold me Tim is 775,494 , the Magnum 18 in it can't be the original 930hr engine. The poor welded assembly drive plate, one thinner and larger spacer under the engine hold by one longer bolt, the drive shaft roll pin replace by a bold are all sign of a previous swap but maybe I don't know what I'm talking about and they are just bad fix.

From serial number :756,300 to 799,999 all 2072 Cub Cadet Magnum 20 engine have 1-1/4 crankshaft, Kohler number 52 014 71-S

That's exactly what Joe send me, a low hour original Cub Cadet in very good condition and a soon I receive the new assemble drive plate I finish this "simple" swap

PS: Someone offer me a PTO

Wow! Really? And how exactly that PTO can hold on that shaft without a Keyway?

Really? I was once going to cut off some of a crankshaft end that was a hair too long this way before I decided to scrap that project. I don't think I would try this. I'd end up with a pear shaped crankshaft.

I'm glad you were entertained, I think some people might have taken me a bit to serious.
