So while I think it's 13cd609g063, one pic looks like 12cd..., d could be a b, and the one after the 2 letters could be a 3,5, or 6, but when searching for likeness, only the 6 fit. What I do know is it's 17 hp, 42", has briggs and stratton engine. It has a pedal for the drive, like to accelerate let go of the pedal and it stops. And the control for blade engagement is with the steering wheel. Thank you for your time, help, and consideration with this!
