The so-called "Live PTO" option for the 8N and NAA was dealer installed.
Manually operated on 8N and hydraulically operated on the NAA.
Operation was conceptually similar to the second "hand" clutch used by AC on WD and WD45 models. Releasing the clutch disengaged traction without releasing the primary (foot) clutch. Accordingly, PTO operation was not affected.
Auxiliary transmissions (usually Shermans) were placed in front of the main transmission to add more operating ratios. Such transmissions affected PTO speed but did not provide so-called "live PTO." Theoretically, there is no reason why an NAA could not have both an auxiliary transmission and a "live PTO" option, but I have never seen one so equipped.
