The bolt is not an operational part, it's a simple fastener. I guess you don't realize that an ORC only goes to work when the implement PTO shaft is caused to spin faster than the tractor PTO output shaft - like when using a rotary cutter on a downhill slope, or when the throttle suddnely goes from full to idle.

Putting the gearshift into neutral means nothing to the ORC, since the PTO drive shaft turns independent of the transmission drive shaft. All it does is buffer the extra RPMs when the spinning blades happen to make the PTO shaft turn faster than the tractors output shaft (like the downhill example).
