For the record, a scarifier is a set of either human or electric motor powered tines, height adjustable, which is used on grass to pull up and clear the dead thatch that lies on the ground between the blades, thereby helping the grass grow, strong and tall and thick, in that oh so British way.

I have no interest in any machine with whirling bl;ades (except, see Monty Pythoins Flying Circus, Series 2 I believe - "The Architects Sketch").

Now that is clear, can I assume that no one so far has any idea about the point of the damn post??????

Just thought I should ask ...... :-)
