The R4030 Self-Propelled Sprayer has a 3028-L (800-gal), 304 grade stainless-steel solution tank that has been designed for growers and custom applicators who seek a highly productive sprayer. This reliable machine can deliver additional yield potential in many cropping conditions.


The R4030 Self-Propelled Sprayer provides the total solution by delivering value through machine performance such as a smooth ride, boom size options of 18.3/27.4, 18.3/30.5, 22/36.5, or 22/40 m (60/90, 60/100, 72/120, or 72/132 ft), dry spinner spreader, and direct injection compatibility in addition to integrated technologies like the optional BoomTrac™ Pro and JDLink™ system.


Uptime and cost of operation have also been improved through decreased daily service points, corrosion-resistant fittings, and additional boom protection with a full boom breakaway and tri-directional breakaways.


The increased capabilities of this machine take this self-propelled sprayer to the next level in meeting ever-changing needs while offering exceptional value.

4 Series Sprayer operator station4 Series Sprayer operator station

When operators first enter the Command View III cab, they will notice that significant changes have been made. Key sprayer controls are more easily accessible to the operator on the redesigned CommandARM™ control panel and the multifunction handle has a more ergonomic fit and feel.

The multifunction handle has six reconfigurable buttons, a scroll to select speed range, and allows operators to better manage their headlands with the Headland Management System (HMS™) button. To finish out the upgrades, the GreenStar™ display has been upgraded to a faster, more user-friendly 4600 CommandCenter™ display, which allows operators to efficiently capture, manage, and transfer data.

Comfort continues to be enhanced by the ComfortCommand™ seat, which offers both fore-aft and lateral attenuation along with 15 degrees of right-hand seat swivel on all cab options. For first-class comfort, the premium cab offers a heated/ventilated leather seat and light-emitting diode (LED) cab lights.

The 4 Series Sprayers are JDLink™ telematics system capable, which enable features such as John Deere Wireless Data Transfer (WDT), Service ADVISOR™ Remote diagnostics, and Remote Display Access (RDA). These integrated solutions enable additional uptime and reduce cost of operation. All of the CommandView III cab features allow operators to run longer hours, increasing the ability to get more acres sprayed in a day.

Machine performance and operator comfort are requirements during long days of operation. The field-proven dual strut independent wheel air-ride suspension reduces overall machine maintenance. This suspension also provides a best-in-class ride, which is expected from John Deere Sprayers, even in the roughest fields.


Additionally, approximately 9 percent of the machine weight has been transferred to the front axle of the R4030, R4038, and R4044, which leads to improved balance and further increases machine maneuverability. These features lead to less operator adjustment in the field and on the road. At the end of the day, a smooth, stable ride allows the operator the ability to travel faster across the field and cover more acres, leading to increased productivity.

Make fewer passes through the field and reduce compaction, as well as time spent spraying, with John Deere booms.


All John Deere booms are more stable due to the swing link suspension, which helps translate rough areas in the field into horizontal (side-to-side) movement of the boom rather than lateral (up and down) movement. This additional stability means increased productivity as the boom now has the ability to more accurately maintain spray height above the crop, delivering a precise spray pattern. The swing link suspension also translates into uptime as the additional stability means less crop damage, resulting in less mechanical boom damage.


The enhanced design allows the boom to unfold and fold faster, getting the operators into the field quicker, and the flat fold design delivers superior transport visibility.

The John Deere 4 Series Sprayers have been designed to address the trend toward increased application rates and the desire for improved loading efficiencies. In fact, the R4030, R4038, and R4044 offer the most efficient liquid fertilizer application systems and the fastest loading times that John Deere has ever offered on this size of sprayers to date.


The solution system has been redesigned from the ground up to streamline plumbing for maximum efficiency and flow rate. The standard-flow system (standard solution pump and single flow meter) delivers 30 percent higher flow rates than previous models, up to 643.5 L/min (170 gpm) of output. The optional high-flow system offered on the R4038 and R4044 comes complete with a high-flow pump and dual-flow meters and delivers up to a 60 percent increase from previous models, equating to approximately 851.7 L/min (225 gpm) of output.


Additionally, load times using the on-board solution pump are up to 30 percent faster. This means operators can get back into the field sooner and spend less time filling. These improvements to the plumbing system all link to enhanced versatility and productivity for operators as they strive to increase the effectiveness of their application passes and drive towards increased yields year over year.

As solution tank mixes become more complex, operators need a better way to manage the products they are mixing in helping to reduce the risk of chemical residue. The integrated direct-injection system provides an additional carrying capacity for raw chemicals and allows injection of single, dual, or triple products directly into the boom depending on installed configuration.

NOTE: Low-volume tanks and pumps must be configured with at least one high-volume tank and pump. High-volume tank and pump can be configured by itself.


Direct injection helps provide quicker changeovers and faster cleanouts while also helping to minimize the risk of using multiple chemicals. This is accomplished by allowing operators the ability to isolate higher-residual-risk chemicals in the injection system while mixing lower-risk chemicals in the solution tank.

The minimum and maximum application rates for each pump are as follows:

John Deere’s intelligent nozzle control system ExactApply helps producers better manage drift and deliver a precise application. By maintaining target rate and pressure over a wider speed range, ExactApply can improve productivity up to 20 acres per hour*.


*NOTE: Assumes a 3.2-km/h (2-mph) average operating speed increase.


ExactApply is offered as a factory-installed option as well as a performance upgrade kit that can be added to existing 4 Series Sprayer models. 


How it works

The ExactApply system features multiple modes of operation including pulse-width modulation (PWM) and individual nozzle control:

  • 15-Hz PWM pulses one solenoid to achieve a consistent droplet size and maintain spray pressure throughout a wider range of speeds and application rates.
  • 30-Hz PWM (combined mode) pulses both solenoids in the ExactApply nozzle body at 15 Hz, providing superior coverage. Combined mode allows ExactApply to have a 25 percent increased flow over current competitive systems in the market.
  • AutoSelect A/B automatically switches between two nozzles to maintain the desired spray pressure range while spraying conventionally.
  • Turn compensation varies the rate across the boom, ensuring the desired application rate. The rate decreases on the inside of the turn to not subject crop to chemical burn, while the rate on the outside of boom increases, ensuring the crop receives the desired application rate.
  • Individual nozzle control minimizes overlap by controlling product application through individual nozzles. This reduces chemical cost and ensures the product is placed where it is needed most. In comparison, traditional nozzle control functions in 11 sections, meaning section widths vary from 2.4 to 3.35 m (8 to 11 ft), depending upon boom width.
