Features

CommandView™ III cab offers unsurpassed amenities
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.

36.6-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 36.6 m (120 ft) boom.

 

All 27.4-m (90-ft), 30.5-m (100-ft), and 36.6-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.

Faster spray and transport speed allow operators to get to the field sooner
Field speeds increased to 40 km/h (25 mph)Field speeds increased to 40 km/h (25 mph)
Road speeds increased to 56 km/h (35 mph)Road speeds increased to 56 km/h (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.

Plumbing efficiencies lead to increased application rates, additional versatility as well as faster loading times

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.

Smooth, stable ride enables operator comfort and better maneuverability

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.

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) 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 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) of dry fertilizer and is capable of holding 6.6 tons of fertilizer (not approved for ag lime) with 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. This equates to a consistent spread pattern across the field and decreased cost of operation for the 4 Series Sprayers.

 

The DN456 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.
