Both technicians are correct. The tractor secondary circuit is indeed actuated by the relay piston in a treadle valve, as stated by Technician A. Technician B is also correct in saying that when a treadle valve is functioning properly, the relay piston is actuated pneumatically. This is how the system is designed to work, with pneumatic pressure being a key component in the operation of the treadle valve and its associated relay piston.
