I must admit I've never thought of it too much but the normal Victa 2 stroke mower runs the same type of set up with the exhaust firing straight down onto the lawn surface, but the only thing that would save the lawn is that the blade disc is rotating and gets in the way of the downward direction of the exhaust creating turbulence thus saving the lawn, but with the edger there's nothing underneath to obstruct the exhaust gases thus the lawn takes the full brunt of it.
Just wondering why this hasn't been brought up before ?
Cheers,
