Overview

When application windows are tight and the hours are long, our new cab keeps you at the top of your game in round-the-clock comfort. Ask your John Deere dealer for details on the all-new R4023 Sprayer with 600-gal. (2300 L) tank and spraying widths of 60 ft. (18m) or 80 ft. (24 m). Perfectly sized for smaller, odd-shaped fields.


Sit back and relax. You're looking at one of the most comfortable seats in the business. The all-leather, heated, ventilated seat features nine vertical and lateral adjustments, back support and a larger seat cushion than before.


More peace and quiet. All-new sound suppression enhancements include a noise-reducing hydro-drive plate, cab insulation, gaskets and isolators to help you get away from it all.


Deluxe sound system. Fire up the new first-class stereo system with 4" x 6" speakers and a subwoofer for all-day listening pleasure.


Big screen monitor. You'll be amazed at the crisp clarity of the high-resolution GreenStar™ 3 CommandCenter™ display. All-new cornerpost display gives you key machine information at a glance. You've got to love the latest technological advances all working together so you don't have to.


Sprayer controls at your fingertips. The smart sprayer-specific CommandARM™ gives you fingertip control of important sprayer functions. John Deere integrated technologies help you with the challenges of balancing the right sprayer adjustments all day for peak efficiency.


Conveniences at arm's reach. Integrated BlueTooth® connectivity. A 12-volt power port for your devices. An electronic adjustable right-side mirror for clear view to the rear of the sprayer. A front pull-down sunshade. Plus three cupholders for your favorite beverage. All to help you feel more relaxed and get more done.


Get settled in. If you spray in rougher terrain such as no-till or strip-tilled fields, the R4023 has a new solution — the Soft Shock option. It's built to absorb the forces these rough terrains can generate, ensuring a smooth ride and accurate spray patterns up to 20 miles per hour.


Easy delivery. The compact size allows for easy trailer loading and storage in smaller buildings.

Provides 129-kW (173-hp) turbocharged PowerTech™ PSS 4.5L Tier 4 diesel engine
    • 4.5L John Deere PowerTech PSS diesel engine

      4.5L John Deere PowerTech PSS diesel engine

    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 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.

Wide or narrow axle available to fit a variety of cropping row widths
    • Wide axle, 234 cm to 307 cm (92 in. to 121 in.)

    • 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.

Redesigned CommandARM™ console and multifunction handle improves operator experience
  • R4023 operator stationR4023 operator station

    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.

Huck®-bolted C-channel frame lays the foundation for a smooth ride

    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.

Soft Shock option for rough or uneven terrain applications
  • 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.
