The present invention relates to a spray boom comprising an end section connected to a second section by an articulation, a holding device intended to keep the end section in an initial position as long as a pivoting force has not reached a certain triggering threshold. After triggering, the return of the boom to the initial position is due solely to the weight of the end section. The present invention advantageously makes it possible to reduce the knocks generated by the devices of the prior art.

Safety device for a spray boom

The present invention relates to an agricultural sprayer the chassis of which comprises a bearing structure intended to support a storage device and a connecting structure intended to support a spreading device. The sprayer is notable in that the bearing structure comprises a single stringer. The present invention advantageously reduces the cost of manufacture of the sprayer.

Chassis for an agricultural sprayer

A connecting device connecting a spray boom to a chassis of an agricultural sprayer, said connecting device is noteworthy in that it consists of a single quadrilateral arranged in a plane which is substantially vertical and substantially parallel to a longitudinal plane of said sprayer.

Connecting device connecting a spray boom to a chassis of an agricultural sprayer and sprayer equipped with such a connecting device

An agricultural sprayer including an induction unit capable of occupying at least one transport position and at least one filling position. A movement of the induction unit automatically predisposes a water circuit of the sprayer with a view to preparing a treatment spray mix. To do this, movement of the induction unit causes the opening or closure of at least one valve of the water circuit.

Agricultural sprayer

A suspension device for a boom of a product spraying agricultural appliance includes elements for mounting the boom on a chassis of the appliance. The suspension device further includes elements to damp a boom movements and adjusting members capable of acting on the boom mounting elements so as to vary a position of a boom instantaneous center of rotation relative to a center of gravity thereof, preferably by modifying a spacing between the center of gravity and the instantaneous center of rotation located higher than the center of gravity.
