Two loosening tools are fitted to a support frame, can be adjusted and their operating width is bounded by blades which cut through the soil in the vertical plane. The shafts of the tools are in the form of plough shares which cut through the soil in the vertical plane and are provided with loosening shares on one side which operate in the horizontal plane.</p> |
