R4044 Sprayer

Experience fuel saving and noise reduction with CommandDrive

Spray more acres per day at a lower cost of operation with the CommandDrive powertrain. You will see an improved system response to maintain consistent application and transport speeds in challenging conditions, while reducing overall fuel consumption and cab noise.

The CommandDrive powertrain comes in base on all R4060, R4045, R4044, R4038, and R4030 Sprayers. This powertrain has the following features:

• Auto Mode dynamically commands engine speed depending on load requirements
• Reduce engine speed and save up to 20 percent on fuel consumption
• 3- to 5-decibel reduction in noise for long hours in the cab
• Single pump flow instead of two
• Improved traction control

4 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.

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.

Solution Command offer push button loading

12-button keypad and micro-display

4 Series Sprayers are available with the SCS and have been completely redesigned to allow quick and easy operation at the load station for all operator skill levels. The optional system allows complete automation at the load station with a 12-button keypad. The features include the following:

• Fill station light on/off
• Pump on/off
• Agitation
• Pump speed increase
• Pump speed decrease
• Eductor on/off
• Master on/off
• Automated rinse cycle
• Visual nozzle check
• Pull-on fill
• Push-on fill
• Target fill

The system also features a micro-display, providing real-time feedback on the system operations, as well as ability to select a rinse method and the ability to monitor progress during the automated rinse function. Overall, the enhanced Solution Command System increases operational performance by increasing ease of use through automation at the load station.

Turn compensation 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.

Connect Mobile actual rate map and pressure map in split screen gives the operator deeper understanding of machine performance

Connect Mobile overview

John Deere Connect Mobile is a solution that utilizes an Apple® iPad® tablet in the cab that provides the operator a better understanding of the sprayer’s performance. Connect Mobile documents and displays several sprayer performance attributes, helping the operator monitor and more easily detect problems that can occur while spraying. Connect Mobile also has a common user interface that makes it easy to use between different pieces of John Deere equipment. Once the job is done, the iPad with the spraying data can be utilized to perform basic crop scouting activities in the field.

Spraying attributes

Monitor key performance indicators in map layers and dashboard tiles such as:

• Actual rate
• Rate deviation
• Pressure
• Ground speed
• Droplet size
• Target rate
• Flow rate
• Tank volume
• Productivity
• Fuel rate

In base equipment

Connect Mobile hardware is factory installed on all model year 2017 and newer R4030, R4038, R4044, R4045, and R4060 Sprayers, making it easy to get started with Connect Mobile.

Keep your machines working for you by converting them to dry nutrient applicators with the addition of a New Leader® DN456 Dry Spinner Spreader. This conversion can be completed in as little as 4 hours and involves the removal of the wet solution skid and the installation of the dry spinner spreader.

The DN456 features a carrying capacity of up 5.6 m³ (200 cu ft) or 6.6 tons of dry fertilizer (not approved for ag lime) and is capable of variable rate applications from 34 kg/ha (75 lb/acre) up to 3 ton/acre. The 1.83-m (72-in.) spinner heights allow spread width up to 32 m (105 ft) as it propels material across the pass. The New Leader G4 spinner technology provides a consistent spread pattern across the field for uniform pass to pass application.
