RB67 power drive back - does it cock the shutter?

[WilmarcoImaging]

Do any of the RB67 power drive backs also cock the shutter and body, in addition to advancing the film?

I downloaded the manual, and searched this site and others, and didn't find the answer. Feedback from users with first hand experience much appreciated! Thanks in advance.

There is no "power take-off" on one of these, so there would be no way that they could cock the shutter.

Nope, those backs just save you having to mess with two levers; take the shot and the film advances, you still do the shutter. RZ may be a different story though?

Thanks for the replies.
