The cylinder with spikes is the lawn rake - I've used that to get loads of moss and thatch out of the lawn - nearly filled the brown council bin just with the small front lawn. Think I used it on the sort of middle setting. Try it and see, it's easy to adjust.
The cylinder with blades is the scarifier. It'll cut slits in the lawn. I've not used it yet as the ground has been so dry and I wanted some rain to soak into the lawn after I'd raked it before I attacked the lawn again. . I'm hoping to use it this week and then brush some topsoil into the slits and scatter some lawn seed over.
If you plough through the instruction leaflet it does explain what height to do each function at - it's not explained terribly well so make a coffee and sit down and ponder over it - with a bit of caffeine it suddenly became clearer
