Edge Master (tm)

This feature doesn’t work as a yard owner would expect.  
1 . It drops to 3cm and scalps the grass
2. It presumably is for edging, so ideally it would just be the edge and possibly a reasonable distance like 6-8cm from the edge. However it is the entire mower width
3. Both it is not blended, which means unless you are cutting all your grass at 3cm you will have a moat circling your yard.  In other words a hard transition edge going from mowing height straight to scalp height

Ideally it would only be the edge bank of blades that are cutting and at an edging depth only 1-2cm lower than cutting height.

Until then, no one is using this because it makes your yard look dumb.
