The item of equipment in question includes utensils that make it possible to clean the strip of terrain to be seeded of residue from the previous crop, and adequately prepare the terrain for seeding that can be carried out using any type of seed-drill that can be attached to the rear of the item. In substance, the aforementioned item of equipment consists of a horizontal support framework (2) to which several identical assemblies (3) are attached at a certain distance from each other. Each assembly includes a tilling plowshare (4) attached to a sprung device (5), two sod-breaker discs (6) attached to the sides of the plowshare, and a rotating cleaner disc (7) with flexible elements (13) attached in front of the plowshare in respect of its direction of travel, on a parallelogram shaped support (9). The sod-breaker discs (6) are attached to a support (8) that can be directly attached to the plowshare holder arm (4 min ), or on a shock-absorber (16) placed between the arm (4 min ) and the support (8), which makes it possible for the sod-braker discs (6) to have a certain degree of independence in respect of the plowshare holder arm, so that they can ride over any residue from the previous crop, and preventing the discs themselves from becoming obstructed. <IMAGE> |
