Abstract: The invention relates to a soil cultivation machine (1) with a machine frame (3) supporting a seed container (4). Sowing shares (11), a driving wheel (9) and curry-combs (12) are articulated to said frame so as to be lifted from an operative position to a resting position. A support (5) pivotable about an axis extending transversally to the seeder (2) is arranged on the rear of the machine frame (3) and the sowing shares (11), the driving wheel (9) and the curry-combs (12) are fastened to said support (5). The structural outlay for lifting is consequently extremely low.

Abstract: A direct drill seeding unit comprising a coulter wheel (5), a pair of depth control wheels (7) and a splitter (9) where the main components of the seeding unit are pivoted on an elongate arm (1) which is connected to a common or main frame (3). The pivotal movement of the unit allows a gang of the seeding units to follow undulating land in a very faithful manner. Furthermore the splitter (9) is capable of variable height and angle relative to the ground level according to the vertical position of the elongate arm such that as the arm moves up the splitter shall automatically compensate by lowering in order to maintain contact with the soil. The adjustment of the splitter is effected by the trapezoid configuration of the 4 pivoting points and the ''L'' shaped common linkages (4).

Abstract translation: 包括犁刀轮（5），一对深度控制轮（7）和分离器（9）的直接钻孔播种单元，其中播种单元的主要部件枢转在细长臂（1）上，细长臂（1）连接到 公共或主框架（3）。 该单元的枢纽运动使得一组播种单位能够非常忠实地跟随起伏的土地。 此外，根据细长臂的垂直位置，分流器（9）能够相对于地平面改变高度和角度，使得当分支器向上移动时，分流器将通过降低而自动补偿以保持与土壤的接触。 分离器的调整通过4个枢转点和“L”形公共连杆（4）的梯形结构来实现。

Abstract: A mounting assembly for a hopper of an agricultural row unit includes a mounting bracket configured to couple to one of the hopper or a frame of the agricultural row unit. The mounting bracket has a first recess and a second recess, the first recess is configured to engage a rod while the hopper is in an engagement position and in a mounting position, the second recess is configured to engage the rod while the hopper is in a mounted position, and the rod is configured to couple to the other of the hopper or the frame. In addition, the mounting assembly includes a support bracket configured to couple to one of the hopper or the frame. The support bracket includes a first protrusion and a second protrusion, and the first and second protrusions form a recess.

Abstract: A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.
