Check page 10 (shown as page 8 on the actual manual)-Engine Deck

The clutch seems to be item 21, and held on only by 1 bolt (item 32)

It doesn't appear that I need to remove the engine, but maybe I don't understand something, am I right?

Trust me, it is twice as hard as you think. The bolt is just a precaution, you need a gear-puller to get the PTO off of the shaft. In the process of getting it off, you will probably run into something with it when removing when on the mower. Maybe you can do it. I've only had to switch PTOs/pullies when the engine is off of the mower.
