<p>The machine (1) has a frame (2) supported to ground by directional wheels (8, 9), and a working device (10) connected to the frame. A front portion of the frame has a pivot connection (11) with a coupling device (13) that is designed to be connected to lower arms (14, 15) of a tractor (4). Center of gravity of the machine is located between one of the wheels and the coupling device. The pivot connection has an axis (12) whose projection on a plane vertical and parallel to advancing direction (A) forms inclination toward the direction by following direction from the ground toward top.</p> |
