Narrow axle, 183 cm to 224 cm (72 in. to 88 in.)Narrow axle, 183 cm to 224 cm (72 in. to 88 in.)

Two axle widths are available to best fit a variety of cropping row widths.

The narrow width axle has a tread width from 183 cm to 224 cm (72 in. to 88 in.) and a clearance of 112 cm (44 in.). The wide axle has a tread width from 234 cm to 307 cm (92 in. to 121 in.) and a clearance of 127 cm (50 in.). Axle range for wide machines varies slightly depending on the option (hydraulic vs. manual tread adjust) that is being used.

 

NOTE: In order to achieve 229-cm (90-in.) tread spacing, IF320/80R42 tires must be used with AN401678 rims. Please see your local John Deere Dealer for more information.

 

With these tread spacings, the R4023 Sprayer holds an impressive 46-54 weight split when unfolded, fully loaded. This weight split helps to reduce compaction through the field and keeps the power to the ground.

The wide axle is ideal for the Midwest grain farmer. With the wide axle option, the operator can straddle three rows at 76.2-cm (30-in.), 81.3-cm (32-in.), 86.4-cm (34-in.), 91.4-cm (36-in.), 96.5-cm (38-in.), or 101.6-cm (40-in.) spacing or four rows at 76.2-cm (30-in.) spacing.

The narrow axle is ideal for the cotton or specialty crop farmer. With the narrow axle option, the operator can straddle two rows at 91.4-cm (36-in.), 96.5-cm (38-in.), or 101.6-cm (40-in.) row spacing.


Cast mount for connecting rods Cast mount for connecting rods

The suspension design on the R4023 Sprayer uses a four-bar link system along with an air bag and shock combination to provide a comfortable ride.

Two large air springs sit atop each axle, similar to those used on over-the-road trucks and other John Deere sprayers. These air springs are dampened with oil-filled shocks to smooth the ride.

Connecting rods link the axle to the large cast mount that is bolted to the C-channel frame with a Huck® bolt. The axle-connecting rods are parallel for vertical motion and cross linked for lateral stability.

Air bag/shock suspension Air bag/shock suspension
#

The R4023 Sprayer's standard suspension provides for 152 mm (6 in.) of travel at the air bag. The air springs are underneath the frame; therefore, visibility of the rows passing underneath is free of suspension components.
 
The air springs are adjusted by adding or removing air through a standard air-stem valve on top of each spring or, if the sprayer is equipped with auto air-spring leveling, the air springs will inflate to the optimum level for the best-possible ride.

Auto air-spring leveling system adjusts for optimal field performance

The auto air-spring leveling system is standard equipment. This feature maintains ride height, ensuring 102 mm (4 in.) of travel up and down at all times for 203 mm (8 in.) of total travel. The operator does not have to individually fill each bag or deflate each bag for transport, saving as much as 10 minutes. A switch located near the solution loading system deflates all four bags at one time. Once the machine is running, the on-board air compressor automatically inflates the bags to the optimal set ride height.

Huck is a trademark of Alcoa Incorporated.


Huck bolt outside frameHuck bolt outside frame
Huck bolt inside frameHuck bolt inside frame

The R4023 Sprayer's great ride begins with the frame. The frame construction allows the R4023 Sprayer to absorb rough field conditions that the operator may encounter. 

The frame consist of two strong parallel C-channels that are connected by suspension castings and reinforcement cross members. The cross members are connected to the frame using Huck bolts. Huck bolts combine the advantages of a high-strength bolt and rivet.

These fasteners provide greater vibration resistance and a joint that will never loosen compared to standard bolts. 

This style of frame and fastener is commonly used on over-the-road trucks and trailers.

Huck is a trademark of Alcoa Incorporated.


The R4023 now offers two factory installed shock solutions to accommodate various field conditions. For optimal comfort in rough or uneven terrain conditions such as no-till or stripped fields, a Soft Shock option is now available.

The Soft Shock will take the place of the adjustable shock dampener used on the 4630 and will be offered as a factory-installed option. This fixed shock provides 50 percent less dampening force which allows for a smooth ride up to 32.2 km/h (20-mph) spray speed in those uneven field conditions. The Soft Shock may also provide a more responsive feel for operators in turns or when starting/stopping quickly.

NOTE: The standard shock option is unchanged from previous models and is recommended for general use.

When operators first enter the model year 2018 R4023 cab, they will notice that there have been significant changes made. Key sprayer controls are more easily accessible to the operator on the redesigned CommandARM 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.


Having the optimal weight distribution results in a lighter footprint leaving less compaction and less damage to the field, allowing the operator to get into the field earlier. 

The R4023 Sprayer was built with the optimal weight distribution.

Interchangeable inner boomsInterchangeable inner booms
3-D boom structure3-D boom structure

The R4023 Sprayer's booms are built with high-strength square tube. 

The boom incorporates a strong 3-D design. This design gives the boom more strength to resist fore-aft loading generated by starts, stops, and turns, as well as twisting loads caused by folding and unfolding operations.

The boom plumbing and nozzles are set between and up inside the two bottom square tubes of the boom structure. This protects the nozzle bodies from hitting objects that could damage the sprayer or affect the spray pattern.

The R4023 boom comes in an 18.3-m/24.4-m (60-ft/80-ft) or 18.29-m/27.44-m (60-ft/90-ft) configuration. Simply fold in the outer wing and go from spraying at 24.4 m/27.44 m to 18.3 m (80 ft/90 ft to 60 ft). When the outer wing is folded over top, it is supported by cradles to ensure it will remain in place and secure while spraying in the 18.3-m (60-ft) configuration in rough fields.

Increased boom sections provide the operator more precise application:

  • 24.4-m (80-ft) boom-5 sections
  • 27-m (90-ft) boom-7 sections

The breakaway ends of the boom offer the operator protection against damaging the boom if the boom unexpectedly hits an obstacle. The breakaway section of the boom uses a design that holds the breakaway from breaking backward while operating normally in the field, but when something is contacted, it will move rearward and out of the way to prevent major damage.

Each breakaway section resets using a spring, and then resets back to the spray position.

When the booms are folded in, the transport cradles on the machine support a large portion of the boom that, in turn, spreads out the stress.

While in transport position, the booms are cradled so that visibility is maximized to either side of the sprayer. By folding the booms flat, visibility is increased and the overall height of the machine is not affected.


Increase productivity up to 20 acres per hour* through wider spray speeds and rate ranges. Better manage drift and improve spray quality and precise application.

 

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

 

Wider speed range while maintaining target rate and pressure

Consistent droplet size is critical to drift management and precise application. The ExactApply system produces a consistent droplet size through:

  • 15/30-hz pulse width modulation that maintains spray pressure throughout a wider speed and rate range
  • Automatic nozzle switching between two nozzles that maintains the desired spray pressure range while conventional spraying
Turn compensation
Control gallons per acre throughout turnsControl gallons per acre throughout turns

Conventional spraying technology applies the same rate throughout the width of the boom while turning, causing under application on the outside of the boom and over application on the inside of the boom.

 

ExactApply 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

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.

Avoid spraying waterways while ensuring coverageAvoid spraying waterways while ensuring coverage

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.

Individual nozzle control mode Individual nozzle control mode

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.

Built with the same kind of innovative thinking as its popular 4 Series siblings, the R4023 Self-Propelled Sprayer combines versatility, productivity, and affordability in a 2271-L (600-gal.) sprayer.

 

The option of either a wide or narrow axle configuration enables this sprayer to fit a wide range of row spacing needs. Additionally, the R4023 offers key features that provide for a smooth ride that is necessary for those long days in the field.

 

Equipped with up to a 27.4-m (90-ft) fold feature, the R4023 allows the operator to fold the boom in quickly for headland turns. With the ability to add precision ag productivity boosting features, the R4023 enables more accurate, efficient, and comfortable spraying applications.

When you buy John Deere equipment, you expect reliability. You also know that problems can happen, and a product is only as good as the support behind it. That’s why John Deere equipment is prepared with technology that senses potential issues and can alert you and your dealer promptly—in the cab or anywhere you are.

John Deere Connected Support is a revolutionary change to support that leverages technology and the connectivity of JDLink© telematics to prevent downtime and resolve problems faster. These tools decrease downtime by an average of 20 percent, enabling faster responses to unexpected problems and reducing technician trips to your machine. For some issues, unplanned downtime can even be prevented altogether through prediction of the issue.

With your permission, John Deere Connected Support:

  • Keeps you running by monitoring machine health and promptly alerting you and your dealer of issues
  • Saves time by remotely viewing in-cab displays, reducing trips to the machine
  • Reduces or even eliminates technician trips to a machine through remote diagnostic and remote software reprogramming capabilities
  • Connects experts with the information needed to respond to downtime faster and prevent it altogether

With more than a decade of experience leveraging connectivity to solve problems, no one else has the experience, tools, and knowledge to keep you running as John Deere and your John Deere dealer can. Connected Support is an in-base feature on all John Deere products with factory- or field-installed JDLink.

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.

 

ExactApply is available as a factory-installed option, as well as through Precision Upgrades and aftermarket attachments. Precision Upgrades for ExactApply are available for 400, 600, and 4 Series Sprayer models. ExactApply aftermarket attachment kits are available for 4 Series Sprayer models.

Built with the same kind of innovative thinking as its popular 4 Series siblings, the R4023 Self-Propelled Sprayer combines versatility, productivity, and affordability in a 2271-L (600-gal.) sprayer.

 

The option of either a wide or narrow axle configuration enables this sprayer to fit a wide range of row spacing needs. Additionally, the R4023 offers key features that provide for a smooth ride that is necessary for those long days in the field.

 

Equipped with up to a 27.4-m (90-ft) fold feature, the R4023 allows the operator to fold the boom in quickly for headland turns. With the ability to add precision ag productivity boosting features, the R4023 enables more accurate, efficient, and comfortable spraying applications.

The R4023 Sprayer provides 129 kW (173 hp) with a 5 percent power bulge to 136 kW (182 hp) and 6071 kg/cu m (538 lb-ft) of peak torque to get through tough field conditions.

John Deere PowerTech PSS (two-valve) 4.5L (274.6-cu in.) engine features include:

  • Four-cylinder, eight-valve head (two valves per cylinder)
  • Cooled exhaust gas recirculation (EGR)
  • Exhaust filters
  • Selective catalytic reduction (SCR)
  • Air-to-air charge air cooler (CAC), aftercooled
  • High-pressure common rail (HPCR) fuel injection system
  • Series turbocharger

In addition to reducing emissions and lowering engine idle noise, its compact size allows it to fit neatly under the hood for great visibility of the rows passing underneath the operator.

An increase in fuel tank size makes it possible to spray for up to 16 hours without refueling. By equipping the R4023 Sprayer with a 310-L (82-gal.) fuel tank, the operator will have plenty of fuel to spray for a full day.

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.

 

Thanks to the addition of an inertia-monitoring sensor that helps correct for chassis roll, BoomTrac Pro 2 offers up to 22 percent greater spray accuracy (composite score over a variety of terrains) compared to the previous BoomTrac Pro system, and a five time increase in the amount of time the boom maintains its target height, which is a real plus in rough or hilly conditions. Along with the improved accuracy and reduced drift, operators will appreciate having one less function to perform and one less thing to worry about.

 

NOTE: BoomTrac Pro 2 is required on all carbon fiber booms.

When operators first enter the R4023 cab, they notice that there have been significant changes made from previous years. Key sprayer controls are more easily accessible to the operator on the redesigned CommandARM console, and the multi-function lever has a more ergonomic fit and feel.

 

The multi-function lever has six reconfigurable buttons, a scroll to select speed range, and allows operators to better manage their headlands with the HMS© headland management system 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.

The BoomTrac Pro auto-boom height-sensing system is designed to help make operators more productive by providing the following advantages:

  • BoomTrac Pro increases application accuracy and efficiency by maintaining a more consistent boom height above the crop; drift and skips can be greatly reduced.
  • Operator fatigue is reduced because the operator has fewer operations to perform. The operator will feel better at the end of the day and pay more attention to the surrounding environment and field conditions.
  • By reducing opportunities for the boom to contact the ground the likelihood of boom damage decreases, which reduces downtime and repair costs.
