John Deere unveiled its unique ExactApply smart nozzle control system for self-propelled sprayer machines at the Sustainability Day in Waldorf, Germany, at the end of May, which greatly improves spraying precision and also provides optimal control of product flow.

The company said in a statement.

“ExactApply automatically maintains the target application rate regardless of spray rate, and the system can control either each nozzle individually or in pairs. What makes ExactApply unique is that the system does not vary in pressure, and this ensures the desired droplet size at speeds ranging from 10 to 30 km/h,” .

says the company

ExactApply uses pulse width modulation technology to control the flow of product through each nozzle. With this technology, a better coverage area is achieved and the desired effect of the drug is obtained.

“For nighttime operation, the system is equipped with LEDs for excellent visibility during operations, which guarantees better application quality in low light conditions. If the nozzles malfunction, the LED warns of a malfunction. In this case, a warning appears on the display, allowing for timely troubleshooting,” the company added.

The ExactApply intelligent nozzle control system is a unique John Deere development. This is the first of a next-generation chemical application control system. Operators will see an immediate increase in productivity through increased speed ranges and spray rates.

The operator will have better drift control, as well as improved spray quality and application accuracy, even on closed curves. The sprayer will treat more hectares per hour, ensuring that every drop gets to the right plant.
