When margins are tight and application windows are narrow, every dollar and every droplet need to work as hard as they can. John Deere’s See & Spray™ Gen 2 brings resource-saving precision to the field.

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.

Automatic Solution Control – Simple. Precise. Fully Electric.

With the introduction of the MY27 Sprayers, Automatic Solution Control is now in base on John Deere 400 and 600 Series Sprayers – eliminating manual solution control valves and moving fully to an electronic system.

 

This update replaces manual flow control valves with electronically actuated valves, delivering a major step forward in ease of use, precision, and operational efficiency. Operators can now control loading, rinsing, and the SprayStar™ Rate Control directly from the cab or the load station, reducing time, effort, and potential for error.

 

The updated system also features a simplified, standardized keypad and labeling shared across machine models – improving usability, streamlines software consistency, and training efficiency.

 

By removing the need for manual valve operation, Automatic Solution Control:

 

• Reduces operator errors during loading and cleanout
• Improves safety and chemical handling by minimizing manual interaction
• Increases accuracy and repeatability of solution control
• Improves overall productivity with faster, simpler operation

 

Unlike manual systems that require the operator to periodically step out of the machine and adjust valves one at a time – often leading to missed steps or incorrect valve positions – the automated solution control with electric low rate/high rate valve system delivers precise, reliable control each time, ensuring the correct rate range is set for the best performance, delivering the right rate in the right place.

Automatic Solution Control – Premium. Maximum Speed. Maximum Cleanliness.

Automatic Solution Control Premium builds on the standard system by adding a dedicated high-capacity fill pump, dramatically increasing loading speed and further improving cleanliness and chemical management.

 

Key advantages include:

 

• Significantly faster fill times, reduced from approximately 12–15 minutes down to 5–8 minutes
• Completely independent solution lines, reducing the risk of cross-contamination
• Fresh clean-water rinsing of the fill pump, solution pump, & eductor, improving cleanout effectiveness and chemical changeover confidence

 

By separating the fill system from the spray system and automating the rinse system functions, the Automatic Solution control Premium configuration not only accelerates pull-on-and-go efficiency, but also raises the bar for contamination control and system cleanliness – making it ideal for operators managing multiple products, chemistries, and application windows.

Quality of application is critical. Avoid settling in the plumbing by keeping solution in motion with pressure recirculation, coupled with product reclaim and boom air purge. These features save precious time, product, and expense when rinsing and priming the boom while switching solutions.

 

Cost savings

• Pressure recirculation primes the boom versus traditional boom prime where liquid tends to be sprayed out, saving 113.6 L (30 gal.) each time. If an operator does this process 10 times a day, coupled with approximately 85.2 L (22.5 gal.) of solution savings with product reclaim one to two times per day, these two features together could save up to $600* a day.
  
  • *NOTE: Assumes 113.6 L (30 gal.) of residual product in the system at 93.5 L/ha (10 gpa) and $20 per acre 10 times per day. Adjust the calculation to suite your operation.
• Reclaim expensive crop protection solutions between applications or required service in the field with product reclaim.
• Potentially reduce crop damage from residual chemical buildup.

 

Performance:

• Experience uniform distribution of product across the boom.
• Reduce nozzle clogging with increased agitation of product in the solution system.

Keep solution in suspension in the boom and system while the machine is on and not spraying with pressure recirculation. Recirculation during rinsing removes any chemical that settled out of the suspension while spraying, resulting in higher rinse water velocity in the spray pipe. Rinse water can be recirculated multiple times to further clean spray pipes and reduce cleanout times. Boom pressure recirculation mixes the solution and primes the boom before spraying to obtain a homogenous chemical mixture throughout the solution system and up to the nozzle tip. This recirculation improves spray quality and reduces time at the start of spraying.

 

Product reclaim transfers chemical out of the boom plumbing into solution tanks to improve boom rinse functions, also reducing exposure when servicing nozzle bodies. Additionally, save on chemical cost and enable easier rinse water collection between rinses when operators are not spraying out of the boom in the field.

 

NOTE: Pressure recirculation and product reclaim kits are available to order as aftermarket upgrade kits through Parts and as Complete Goods through precision upgrade. Precision upgrades offers kits for 400, 600, and most R4 Series Sprayers while Parts offers kits for R4030-R4060 Sprayers.

With the CommandDrive powertrain, save fuel, reduce cab noise, get improved traction in challenging conditions, and cover more acres per day. CommandDrive offers the operator an Auto Mode that automatically directs the engine to run at the lowest rpm necessary to maintain ground speed and hydraulic functions and to meet the demands of the solution system.

 

CommandDrive also allows operators to adjust the aggressiveness of acceleration and deceleration and features an Auto Idle system that reduces engine speed to 900 rpm when the machine is in park. It all adds up to:

• 20 percent or greater fuel savings
• More acres sprayed per day, thanks to fewer fuel stops and improved traction in rough conditions
• Reduced in-cab noise levels by 3to 5 decibels
• Fewer demands on the operator

 

CommandDrive is base equipment on all 408R, 410R, 412R, 612R, and 616R Sprayers, as well as 400R and 600R Dry Spinner Spreaders.

For the highest level of spray accuracy with less drift and reduced risk of boom damage, look to the BoomTrac™ Pro 2 automatic boom-height control system.
