Genuine Wolf Garten Soil Miller 15cm Multi-Change Part crumbles heavy soil into a fine tilth, removes weeds and prepares the ground for planting and sowing seeds. It also helps mix peat, manure and fertiliser into the soil with minimal effort. The rear blade provides you with greater control by keeping the tool at a constant depth while you work. The roller motion allows you to get the job done quickly, making it ideal for use in large areas.
