Take advantage of the R4023 designed for versatility

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.

24.4-m and 27.4-m (80-ft and 90-ft) booms can fold in outer wing to spray in tight spaces

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 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.

Provides 129-kW (173-hp) turbocharged PowerTech™ E 6.8-L Tier 3 diesel engine

The R4023 Sprayer provides 129 kW (173 hp) with a five 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.

A 280-L (74-gal.) fuel tank makes it possible to spray for up to 16 hours without refueling. By equipping the R4023 Sprayer with a 280-L (74-gal.) fuel tank, the operator will have plenty of fuel to spray for a full day.

Handle rough and uneven terrain with ease through soft shock technology

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.

Air bag/shock suspended axle provides a comfortable ride even in rough conditions

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.

Fit variety of cropping row widths with wide and narrow axle options

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.

Optimal weight distribution means operator can get into field earlier

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.

ExactApply™ nozzle control delivers precise application with up to 20 acres per hour of added productivity

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*.

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.
