摘要： The seed drill element comprises a frame, a seed tank, a seed dispenser, and a member for opening a furrow in the ground. The seed drill element further comprises mechanism for bearing against the ground, having a rear block and/or a front block, with each block having at least one wheel and an arm hinged to the frame, and also topsoiling mechanism including a rear link, two front links, and an intermediate link. The topsoiling mechanism also comprise a mechanism for moving the rear link relative to a reference part connected to the frame. In addition, the seed drill element includes a locking mechanism so that the topsoiling mechanism can be configured for front topsoiling, for rear topsoiling, and/or for rocker topsoiling.
