<p>The device is assembled of two parallel positioned bars (1) to be adjusted regarding their distance from one another with two screws (11, 13). A transversal handle (12) is attached to the upper, cranked ends of the bars (1) and blade units (2, 3) to each of the lower ends. The blades (2, 3, 4) are swivel mounted with bolts (5) guided through bores formed by the separately added tips (10) and the lower ends of the bars (1). When the bars (1) are pushed into the soil, the blades (2, 3) are folded close to the device, protected from a premature wear and tear.</p> |
