The device (1) to carry out slotted agricultural drain according to the present invention comprises a supporting frame (2) attachable to wheeled or caterpillar vehicle (3). The supporting frame (2) is provided with a hopper (4) for bulk material (5), particularly sand or gravel, and a feeding device (6). The supporting frame (2) is further provided with a share beam (7) with an edge (8) for cutting through the soil, wherein said share beam (7) is provided in its lower portion with a digging shoe (9) covered by a bit (10). The share beam (7) is further provided with bulk material (5) inlet opening (11) from a storage bin (4) and a rear outlet opening (12) for proportioning the bulk material (5) into a trench of the slotted agricultural drain. The share beam (7) is performed as a hollow body with a cavity (21) extending all over the length of the share beam (7) from the upper edge to the lower edge thereof. The share beam (7) rear side features a quadrangular rear outlet opening (12), which is provided with a slidably adjustable rear slide (13). On the share beam bottom side, after the digging shoe (9) there is provided a quadrangular lower outlet opening (12´), which is provided with a lower sliding slide (13´) for controlling the height and thus amount of the bulk material (5) in the drain layer (16).
