Trailer sprayer METRIS 4102 AUTOSPRAY

Modern agriculture, especially with the widespread use of simplified soil treatment systems, is inconceivable without applying mineral fertilizers, pesticides (herbicides, fungicides, insecticides), desiccants, etc. However, agronomy and its technical equipment have become increasingly complex!

Special faculties have emerged in rural universities to train specialists in plant protection from weeds, pests, and diseases. Developing, manufacturing, selecting, and operating sprayers have become some of the most challenging tasks in agricultural technical support.

What criteria do farmers use when choosing a sprayer?

  • Ensuring the application of necessary plant protection products (PPP) with a specified rate, uniformity, and high productivity per unit area, within optimal and very tight timeframes, at different stages of plant development.

  • Quality application of chemicals on fields with various terrains (slopes, complex-shaped plots, unevenness, presence of obstacles such as poles, hydrants, etc.) and under different weather conditions (wind, air humidity).

  • Providing various types of nozzles to allow for the selection and precise adherence to the desired spray pattern, droplet size, and structure depending on the chemicals, type of work, stage of plant development, and wind strength.

  • Having a lightweight and compact sprayer design to reduce ground pressure, prevent rut formation during numerous passes, adhere to transport dimensions, and ensure maneuverability and stability on turns and dirt roads.

  • Offering a wide range of models with different pump types for selecting pressure and flow, various tank sizes and hoses, suspensions, and control systems for optimal configuration selection based on field size, shape, and relief, cultivated crops, soil treatment technologies, distance from water sources, etc.

  • Ensuring ease of cleaning, maintenance, and performing preventive tasks such as lubrication and replacing worn or chemically affected components.

The wide range of sprayers manufactured by the KUHN group of companies allows farmers to choose the one that best meets their needs. Among all the manual, backpack, mounted, trailed, and self-propelled KUHN sprayers, let's consider the trailed model Metris 4102, which incorporates the first and only Autospray technology in the world, developed by KUHN-Blanchard engineers.

The Metris 4102 sprayer model has proven to be quite confident and enjoys great demand in the global market, satisfying all the above needs of even the most demanding farmers.

For instance, one of the points - "spray pattern, droplet size, and structure", regardless of the discharge rate of the working fluid and sprayer speed, can be ensured by Autospray technology with maximum quality and using only one type of nozzle that encompasses the desired parameters. Since the maximum effectiveness of the working solution depends not only on the specified rate but also on the size and structure of the droplets, the farmer only needs to choose the type of nozzle, and Autospray will handle the rest depending on the sprayer speed and the specific needs of each area of the field.

  • The farmer selects the correct rate of working fluid consumption and the precise droplet size.

  • Based on this, they choose only one type of nozzle that meets the desired discharge rate and effective droplet size at minimum and maximum pressure in the system for its quality operation.

  • The Autospray system, in the "ISOBUS" application, selectively controls "smart" nozzle holders, strictly adhering to the consumption rate and maintaining the necessary pressure in the spraying system to form the precise droplet size depending on the speed and demand.

  • The advantages of the Autospray system lie in its ability, with the correct choice of nozzle type, to ensure high-quality sprayer operation, strictly maintaining a stable droplet size when changing consumption rates within the speed range, for which traditional spraying systems would require 4 or even 5 types of nozzles.

  • The Autospray system manages the sequential switching off nozzles to avoid overlapping, and importantly, it works on the edges of the field, guaranteeing safe sprayer operation for the environment, preserving yields, and significantly saving farmers' costs.
