  • Faster spray and transport speed allow operators to get to the field sooner
    Field speeds increased to 40 kph (25 mph)Field speeds increased to 40 kph (25 mph)
    Road speeds increased to 56 kph (35 mph)Road speeds increased to 56 kph (35 mph)

    Efficiency and productivity are key drivers to any successful application operation. To meet this need, the R4038 and R4045 have increased spray and transport speeds allowing operators to get jobs done faster and move onto the next field sooner. Operators can now travel 25 percent faster across the field, allowing them to spray more acres per day. Transport speed has also been increased by 16.5 percent, which gets operators to the next field quicker. This translates into a 40 km/h (25 mph) spray speed and 56 km/h (35 mph) road transport speed, boosting overall productivity throughout the day.

  • 36-m (120-ft) boom with swing-link suspension eliminates additional passes through the field

    Make fewer passes through the field and reduce compaction, as well as time spent spraying, with the optional 36 m (120 ft) boom.

    All 27-m (90-ft), 30-m (100-ft), and 36-m (120-ft) booms are more stable thanks 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.

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

  • Dry spinner spreader compatibility increases versatility by allowing the conversion of a machine with a wet solution system into a dry nutrient applicator with a 5.6- m3 (200-cu ft) or 8.5-m3 (300-cu ft) carrying capacity

    At the end of the spraying season operators can keep their sprayers working for them by converting them to dry nutrient applicators with the addition of the New Leader® DN456 or DN485 Dry Spinner Spreader dependent upon the dry product they wish to apply. This conversion can be completed in as little as four 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) of dry fertilizer or Ag lime while the larger DN485 features a carrying capacity of up to 8.5 m3 (300 cu ft) of dry fertilizer only. The DN456 is capable of holding 6.6 tons of fertilizer or 10 tons of ag lime and the DN485 is capable of holding 10 tons of fertilizer with variable rate applications from 34 kg/ha (75 lb/acre u)p to 3 ton/ha (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. This equates to a consistent spread pattern across the field and decreased cost of operation for the 4 Series Sprayers.

    The DN456 and DN485 can be ordered with either 304 stainless-steel or 409 painted spreader material, single or dual product bin configuration, with either #4 belt over chain or #5 straight belt conveyor configurations.

    Field-installed 889-L (235-gal.) direct-injection systemField-installed 889-L (235-gal.) direct-injection system

    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 of up to 511 L (135 gal.) on model year 2015 and older R4030/R4038 (serial number 10,999 and lower) machines and up to 889 L (235 gal.) on the model year 2016 and newer R4030/R4038 (serial number 11,001 and higher) and all model year R4045 machines for raw chemicals and allows injection of single, dual, or triple products directly into the boom depending on installed configuration. 

    MachineCarrying capacityMaximum number of chemicals injected
    R4030/R4038 model year 2015 and older (SN 10,999 and lower)511 L (135 gal.)Two -one high volume, one low volume
    R4030/R4038 model year 2016 and newer (SN 11,000 and higher)889 L (235 gal.) Three-two high volume, one low volume
    R4045889 L (235 gal.)Three-two high volume, one low volume

    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.

    Not only can this help provide quicker changeovers and faster cleanouts, it also helps lower 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.

    Direct injection can help expand the versatility that an operator has throughout the day while adding additional performance and uptime as they manage the product that they are applying.

    Model year 2017 direct-injection systems (attachments BKK10302, BKK10303, BKK10304, BKK10305) will have pump rinse functionality added. Pump rinse functionality can also be added to a current direct-injection system by adding a three-way inlet valve to each DI pump. The three-way valve connects on one port to the chemical tank for normal operation (injection) and to the clean water rinse tank on the other port (for daily pump rinse).

    This feature allows for rinse water to be pulled from rinse tank, through the pump head, and out of the boom mixing chamber. This yields the following benefits:

    • Automatic rinse system, integrated with pump operating modes, cleans chemical out of pump
    • Reduce chemical residual buildup in pump
    • Improved maintenance process, while enabling product to be stored in direct-injection tanks between operation
  • Monitor sprayer performance in the cab

  • Load Command™ system offers unmatched loading performance

    Custom applicators are consistently looking for ways to achieve more acres per day. For this, John Deere offers the Load Command system, a fully-integrated solution designed specifically for the R4045 Self-Propelled Sprayer.


    With this solution, load applicators are able to load 4542 L (1200 gal.) of liquid in as fast as 3 minutes. This increased loading time allows for more spraying time or more acres per day.


    The Load Command system is a revolutionary product that further complements the three-season asset-utilization value offered by John Deere’s largest sprayer.


    How it works


    The Load Command system allows the operator to pull the sprayer up to the tender unit, couple the Load Command tender arm to the Load Command coupler on the sprayer, and receive a full 4542-L (1200-gal.) load in as fast as 3 minutes.


    Load Command dramatically reduces the fill time and the amount of operator interface time. When the system completes loading, the couplers automatically disengage from each other. This allows the operator to remain in the cab with the ability to quickly return to spraying.


    By providing improved loading times, the John Deere R4045 Sprayer with Load Command is more versatile, more productive, and will provide a better overall return on investment.


    With the ability to create more spraying time, the Load Command system enables a custom applicator to achieve more value by applying products more efficiently and, in turn, generating more revenue per season.


    NOTE: Load Command and Front Fill are not compatible to be installed on the machine at the same time. Additionally, load Command is compatible as a field-installed bundle for the 4542-L (1200-gal.) 4940 machine as well.
