Turn compensation mode

Individual nozzle control mode

Fertilizers and crop protection products are too expensive to waste, and seed is too valuable to risk over- or under-treating. To help make sure your solution is getting to the crop at exactly the right rate and droplet size across a wider range of speeds, look to ExactApply nozzle control system.

The heart of the ExactApply system is a six-nozzle turret with multiple modes of operation to help maintain target rate and pressure. From the cab, operators can choose:

15-Hz pulse-width modulation (PWM) pulses one solenoid for more consistent pressure and droplet size over a wider range of ground speeds and application rates.
30-Hz PWM pulses both solenoids at 15 Hz for more thorough coverage during high-volume applications, like liquid fertilizer.
AutoSelect A/B mode automatically switches between two nozzles to maintain a constant spray pressure while you’re spraying conventionally.
Turn compensation mode decreases the spray rate on the inside of a turn while increasing the rate on the outside, ensuring consistent application across the entire width of the boom.
Individual nozzle control minimizes overlap by controlling spray application at the individual nozzle level, not in 2.4- to 3.35-m (8- to 11-ft) section widths.

By maintaining a target rate and pressure over a wider range of speeds, ExactApply lets you cover up to 20 more acres per hour (based on a 3.2-km/h [2-mph] increase in operating speed) with more consistent spray deposition, saving you input costs and preserving more of your crop’s yield potential.

New for model year 2026, John Deere is introducing ExactApply Multi-Rate which enhances our ExactApply nozzle capabilities by enabling the delivery of multiple rates across the eleven sections of the boom in a single pass, regardless of the boom length. This innovation allows for improved rate resolution, particularly while utilizing application prescriptions. Now operators can target specific zones for optimized application, which will enhance crop consistency across varying field conditions. Critical uses include tailored fertilizer for small grains and corn, based on plant and soil conditions, such as top-dressing in wheat, as well as pre or post emerge nutrients for corn.

ExactApply Auto Select Pulsing with A+B Nozzle Switching, enables the Multi-Rate function, expanding performance and speed ranges while ensuring proper droplet size and placement. It also significantly increases the rate range during curve compensation, allowing versatile utilization across all three nozzle configurations within the eleven sections for optimal application.

ExactApply Multi-Rate is a software update included in order code 4985- John Deere ExactApply Nozzle Control and available on model year 2026 R4023, 408R, 410R, 612R, as well as the 616R sprayers. It is also compatible with model year 2022 and forward. A+B Switching and Pulsing compatible with all ExactApply configurations.

ExactApply is available as a factory-installed option, as well as through Aftermarket Attachments and Precision Upgrades.

ExactApply aftermarket attachment kits are available for 4 Series Sprayer models.

Precision Upgrades for ExactApply are available for 400, 600, and 4 Series Sprayer models.
