## Abstract

A single seeder with a foldable chassis composed of a central section arranged transversely with respect to the direction of work and of two lateral sections articulated on the central section, seeder elements being distributed in a regular manner on the chassis, the seeder including burying coulters for the distribution of product extending at the front of a respective seeder element, a distribution head and pipes connected on the distribution head and ending at the burying coulters. The distribution head is arranged at the rear of the seeder, behind the seeder elements, taking into account the direction of advance.

## Claims

### Claim 1

A single seeder, comprising:
a foldable chassis including
a central section arranged transversely with respect to a direction of work, and
two lateral sections articulated on the central section,
seeder elements distributed on the foldable chassis,
burying coulters for the distribution of product extending at a front of a respective seeder element,
one distribution head, and
pipes connected on the distribution head and ending at the burying coulters,
wherein the distribution head is arranged rear of the single seeder, behind the seeder elements, with respect to a direction of advance.

### Claim 2 (depends on 1)

The seeder as claimed in claim 1, wherein the distribution head extends beyond a displacement zone of the seeder elements between a work position and a transport position.

### Claim 3 (depends on 1)

The seeder as claimed in claim 1, wherein one movable guide allows the guiding of the pipes supplying the burying coulters mounted on the lateral sections.

### Claim 4 (depends on 3)

The seeder as claimed in claim 3, wherein each movable guide has a base, the base is connected to a beam of the lateral section and extends perpendicularly to the beam of the lateral section, being inclined by an acute angle with respect to the horizontal.

### Claim 5 (depends on 3)

The seeder as claimed in claim 3, wherein each movable guide has a curved shape directed towards the distribution head in a work position and having an opening angle greater than 90°.

### Claim 6 (depends on 3)

The seeder as claimed in claim 3, wherein each movable guide pivots freely about an axis of the movable guide, the axis of the movable guide being directed according to an acute angle with respect to the horizontal.

### Claim 7 (depends on 3)

The seeder as claimed in claim 3, wherein the pipes extend behind the seeder elements, taking into account a direction of advance during a displacement of the lateral sections towards a transport position.

### Claim 8 (depends on 3)

The seeder as claimed in claim 3, wherein a flexible guide supports the pipes between the distribution head and a respective movable guide.

### Claim 9 (depends on 1)

The seeder as claimed in claim 1, wherein the distribution head extends in a median vertical plane of the single seeder.

### Claim 10 (depends on 1)

The seeder as claimed in claim 1, wherein the distribution head extends in a vertical space occupied by the single seeder during transport.
