Oh, you have no choice but to turn it. That's why I mentioned the timing port can also double as an access point to lever (rotate) the flywheel around. Look at the middle photo above, specifically at the little bit of shiny metal near the top left corner. That's an outside edge of the throwout bearing (TOB). It has a sturdy metal case, the vertical edge of which faces the clutch release fingers (to the right). When you push down on the clutch pedal, the TOB is moved toward the clutchpack. The vertical face pushes the fingers, which in turn disengages the clutch(es). Letting up on the pedal obviously then engages the clutch(es). The gaps between the bearing face and the clutch finger tips is critical to proper and timely clutch operation.
But before we go into this any further, it's important to know which clutch is in your tractor. Start by counting the fingers. Mark one with a piece of chalk. Rotate the clutchpack and count the fingers. Obviously, when you see the chalk mark again, you've finished one full rotation.
