A device for planting seeds in the ground having an inlet orifice via which an airstream transporting seeds arrives, an outlet orifice via which the seeds are planted in the ground and a separating device. The separating device includes a grating which lies substantially in the continuation of the airstream and seed inlet orifice so that a maximum of the air escapes through this grating and the seeds are held back.

Seed planting device and seed drill using such devices

A disk colter has a main disk for making a furrow in the ground. A secondary disk keeps the furrow open over a long enough distance that one or more seeds can be deposited. A support member supports the disks which are mounted so that they can rotate freely and are inclined in such a way that their peripheries meet in a region where the disks are closest to each other. This region is located at a bottom front part of the colter. On the main disk and/or the secondary disk, there is a plugging member intended to plug, at least in a vicinity of the region, a slot between the main disk and the secondary disk so that earth and/or plant debris are prevented from accumulating between the disks at least in the region.

Disk colter for seed drills

The ends opposite one another of adjacent bars (2, 3) of (4, 5) are sized, shaped, and positioned to cooperate with one another to push back hard objects which are found between two adjacent bars (2, 3) or (4, 5) during their approaching phase.

Machine for working soil

In a machine for working soil, the oscillating arms 6, 7 of the opposite toothed bars 2, 3, 4, 5 on different rows 27, 28 are mounted at least approximately side-by-side in a direction crosswise to the direction of advance 24.
