This part is wonderful ..... The first Unkrautstecher which meets all the conditions. My lawn (clay !!!!) consisted of one third dandelion. Within an hour I was able to bring almost effortless two big boxes full of earth. Often roots remain in the ground, because the gripping prongs may be a bit short. The only slight drawback with my ground: it sticks too much ground at the roots. I would theroretisch abklauben and clog the holes in the ground. I do not, but they are easy to kick. They now serve avowedly for ventilation. The part is unrestricted HIGHLY RECOMMENDED !! Especially for older like me ..... it is fun !!!
