I am not 100% sure, but I think so...but thinking has gotten me in trouble before so proceed with extreme caution
I know on mine (NOT E-Hydro), I have to raise the seat and pull the seat switch UP to use the PTO off seat.
I just looked up the manual
online:
I guess I am wrong...
NOTE: The rear PTO can be engaged with the operator off the seat. The Safety Interlock System will stop the engine and all implements if the mid-PTO is engaged and the operator gets off the seat. Engaging Rear PTO
