Black And Decker Lawnraker. Model number LB100-H1
I don't use a Lawnraker or scarifier, so I have no idea whether this one works. (as it was last used over 15 years ago) and has been sitting in the shed for a long time.
You will need an extension cable with the right kind of connector to attach it to the mains electricity.
