| 摘要 |
The invention relates to an agricultural machine for soil-cultivation, comprising, in the direction (F) of travel of the machine, a first row of cutting wheels arranged at right-angles to the said direction of travel and having substantially horizontal axes, in front of which is arranged a cylindrical roller with the aid of which weeds and/or the remains of past cultivation, such as stalks, stubble, and the like may be broken up. A subsequent row of ripping elements, with blades preferably running out to a point, rips up and loosens the soil, without ploughing it in, and is associated with plough-mould-boards which partially plough in the loosened soil. A transverse row of rotor-tools, with substantially horizontal axes, acts as a harrow and is used for final ploughing through 180 DEG and for crumbling the soil. The cutting wheels and the rotor-tools are arranged with their axes at an angle to the perpendiculars to the direction of travel (F) of the machines, preferably at an angle of between 5 DEG and 45 DEG , whereas the ripping elements run in the said direction of travel (F).
