<p>The invention relates to an agricultural soil cultivation device, comprising a frame (1), a transport chassis (7), which is arranged such as to be height-adjustable relative to the frame (1) by means of first double-acting hydraulic cylinders (14) and which has running wheels (6), at least one soil roller (9) optionally arranged behind the soil cultivation tools (2) so as to be height-adjustable by means of two double-acting hydraulic cylinders (15), and supporting wheels (5) arranged in the front region of the frame (1) such as to be height-adjustable relative to the frame (1) by means of third double-acting hydraulic cylinders (17). In order to achieve a simplified working-depth adjustment of the device both with soil rollers (6) arranged on the device and in the use case in which the soil rollers (9) are removed from the device, it is provided that the at least one first double-acting hydraulic cylinder (14) has two cylinder chambers (21, 22) separated from each other by a separating wall (28), that a respective piston rod (25, 26) connected to a piston (23, 24) is arranged in the first (22) and second (21) cylinder chamber of the first hydraulic cylinder (14), that two respective hydraulic connections (30, 31, 32, 33) are associated with the two cylinder chambers (21, 22) of the first hydraulic cylinder (14), such that each cylinder rod (25, 26) of the first hydraulic cylinder (14) can be controlled in a double-acting manner, and that spacing disks (29) are associated with at least the cylinder rod (25) arranged in the second cylinder chamber (21) of the first hydraulic cylinder (14) in order to adjust the stroke of said cylinder rod (25).</p> |
