Thanks BB,

I mentioned initially that I had once used a borrowed SB45 on a lowish setting and my lawn had seemed to die completely. There were magpies all over it , and it seemed to me that lawn beetle had done this and I hope I have this under control now. If I go crazy with the mower and scalp it right down, could this happen again?

I have a rotary mower that can go a lot lower than I have mowed it before. I find any lower than 5 and I scalp some areas of the lawn with bumps. I could go really low (a setting of 1 would be dragging the blades close to the wheel height). I am concerned with killing it all by going too low... Going to take some convincing of my wife who has threatened consequences if I kill it like a couple of years ago!

Finally.... Spring is the time to do the scarification, but it sounds like your suggestion of scalping with the mower could be a similar impact on the lawn. Could I just do the scarification now?

Yeah... lots of nice houses where I live.... but only a few really nice lawns. Mine is one of the better ones now, but my neighbour is probably the best... so I have to lift my game!!
