And then you don't know what counts you're missing when either cylinder is actuating. But maybe that's not an issue if you never actuate the PTO cylinder until the end, and you can keep track of things well enough.

Seems it'd be more reliable if you can put an encoder on the carrier plate/ring gear themselves (a wheel side encoder might be all you need, if zeroed properly), or just have them automatically engage from any position.

Ideally a hall effect sensor + magnet on the ring and on the carrier would work.
