Description of machine The implement is a trailed sprayer for use on ground crops. The sprayer is attached to the tractor via the towing hook.

The machine frame is made out of hot galvanised steel, the main and auxiliary tanks are made out of polyethylene. The main tank is equipped with two gauges, one on the front right and the other on the left side. The liquid level is indicated by a transparent external tube with float. Agitation is via hydraulic stirrers located at the back of the tank. The tank is completely emptied using a valve located on the left side. Access to the main tank if directly from the ground.

The implement is powered via the tractor PTO having a rated power of 540 rpm.

The implement is endowed with a piston-diaphragm pump located in an ad hoc space in the front section of the main tank. Pressure regulation and liquid dispensing are controlled using electrically operated controls that can be placed in the tractor cab.

There are 2 filters: one suction filter, which can be inspected even if the main tank is full, and one discharge filter.

The pressure gauge for checking operating pressure is positioned on the front of the main tank. It has a diameter of 100 mm, end scale of 60 bar and is in intervals of 1 bar.

Liquid is sprayed under pressure, while drops are conveyed via an airflow generated by an axial fan. The dispensing system consists of the axial fan with collector-conveyor endowed with systems to regulate airflow. The speed of rotation of the fan may be modified via a 2-speed gear (+ disengagement). Air is suctioned on the rear side of the machine. It is possible to interrupt the air flow on one of the two dispensing sides by means of bulkheads that are moved manually.

Nozzle holder units, endowed with membrane antidrip devices, are located inside the air outlet section. Each nozzle can be closed singly to adjust the distribution profile in relation to the vegetation being treated.

The strainer basket filters located on the openings of the main tank contain a bottle washing device and a powder mixer.

The main tank is equipped with an internal washing system using a rotary nozzle.

On the right side of the machine is a spray gun for washing the outside of the machine.
