The part of friend you turn from the top of the weeds, a 360 degree turn, Pull out the part and like a shotgun, you will come across the plant over a bucket out again. The three-part spiral, as well as the Austoßer are made of steel and act indestructible. And we really are talking about steel and not just trumpet sheet. Of course, due to the system holes remain in the lawn, which looks a little indeed to attack low-flying aircraft. No matter, I can live with ... :-)
