In order for the lawn deeply rooted and is resistant, I laid me this part to before the last spring. My first attempt to use it in dry clay soil Frankish, ended after 5 sqm. The next attempt was carried out in wet ground and was terminated after about 20 square meters. In clay soil dryness is just too strong to get all the waves in the ground. You have probably bring 150 kilos and shoes with metal soles have (kicking expresses scary to her feet) to permanently be able to exert the necessary pressure. When clay is wet, he is indeed soft, but works like crazy. Now, however, the moist clay clogs the tines in a tour that you are more concerned with making the parts clean again, as follow up of the actual task. In the tines, the wet adhesive clay compacted so much that he will not get out forced upward. It is the, one weighs 150 kilos and has metal soles .. In the sandy soils of the world, however, the part should work. Processing acts stable and has my tests carried out by force and then designed on the basis of which part Aggression unscathed. For 2 stars.
