Deere reveals intelligent sprayer nozzle control
ExactApply system features Pulse Width Modulation (PWM) technology for more efficient and precise sprayingFrom 2018, John Deere's 4 series sprayers will feature the new ExactApply nozzle control system, which has been designed to offer greater accuracy in spraying operations.
"The new ExactApply system was developed for producers and ag service providers who seek a higher level of control of product applications, especially improved application efficacy and accuracy in all field shapes and sizes," says John Deere product marketing manager for crop protection and nutrient solutions, Doug Felter.
Its standout feature is the Pulse Width Modulation (PWM) system, which John Deere claims offers three times the pulsing frequency of traditional PWM systems on a wide variety of nozzles.
"This allows the sprayer to run at a constant set pressure and droplet size, regardless of the sprayer speed and application flow rate, for improved spray coverage across the entire field," Felter says.
The ExactApply system also gives operators the ability to switch spraying between two pre-selected nozzles from inside the cab. The system automatically varies the rate across the entire boom, ensuring the right amount of material is applied to the right area of the field, even while turning.
If a nozzle is plugged, operators will be notified about it.
Each individual nozzle features LED lighting for improved visibility of spray pattern in low-light conditions.
According to John Deere, customers can save two to five per cent in herbicides or pesticides using the ExactApply system.
ExactApply is compatible with all boom sizes equipped with stainless steel plumbing. A major benefit of the new system over John Deere's Section Control, according to the company, is full variable-rate and shut-off functionality at the nozzle level (every 381 to 508mm).
It is fully integrated with John Deere's GreenStar 2630 Display and SprayStar control system, making it compatible with the entire suite of John Deere precision and data management products.
