John Deere ExactApply Retrofit Kits Available for Existing 4-Series Sprayers 

If you own a John Deere 4-Series sprayer (2014 to 2018 model years), you can gain greater accuracy and control of your spray applications by installing the ExactApply retrofit kit. 

Due to its Pulse Width Modulation (30 Hz pulsing) and automatic A/B nozzle switching from the sprayer cab, the ExactApply nozzle-control system equips operators with a comprehensive solution that improves the coverage and control of a spray application. Introduced in 2016 as a factory-installed option for 2018 sprayers, the system also offers operators turn compensation; individual nozzle on/off control; and smart diagnostics to improve, monitor, and document sprayer applications at the nozzle.

“Due to the ever-increasing demand for greater precision, control, and documentation of spray applications, ExactApply has rapidly become a very popular option on new 4-Series sprayers,” explains Doug Felter, product marketing manager for application equipment at John Deere. “Now operators of model year 2014 and newer R4030, R4038, and R4045 machines have the same ability to precisely manage droplet size and coverage of products being applied, enhancing the accuracy and efficacy of the applied products while optimizing input costs.”

Retrofit-equipped sprayers also offer customers:

  • The ability to switch between two preselected nozzles with the push of a button from inside the cab.
  • Full variable-rate functionality at the nozzle level to ensure the correct amount of material is applied to the right area of the field, even when turning.
  • LED lighting on each individual nozzle for improved visibility of spray pattern in low-light conditions.

“ExactApply nozzle control is fully integrated with SprayStar and the GreenStar 2630 or 4600 CommandCenter display, making it compatible with the entire suite of John Deere precision and data management products our application customers are using,” adds Felter. “Large producers and ag-service providers will see significant improvements in spray performance, coverage, and accuracy, especially on hills, turns, point rows, and irregular-shape fields.”

Kits are available for all R4030, R4038, and R4045 sprayers manufactured since these models were introduced that are equipped with stainless-steel plumbing and steel booms, no matter the boom size. Kits include new ExactApply nozzle bodies, new electrical boom harnessing to power and control the nozzles, and a higher capacity alternator for the machine to provide the added electrical power demands.
