• New efficient 4.5L Tier IV engine

Features may include:

• 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.

• Equipped with up to a 27.4-m (90-ft) fold feature, the R4023 allows the operator to fold the boom in quickly for headland turns. With the ability to add precision ag productivity boosting features, the R4023 enables more accurate, efficient, and comfortable spraying applications.

• 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 3D 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 boom plumbing and nozzles are set between and up inside the two bottom square tubes of the boom structure. This protects the nozzle bodies from hitting objects that could damage the sprayer or affect the spray pattern.

• The R4023 boom comes in an 18.3-m/24.4-m (60-ft/80-ft) or 18.3-m/27.4-m (60-ft/90-ft) configuration. Simply fold in the outer wing and go from spraying at 24.4 m/27.4 m to 18.3 m (80 ft/90 ft to 60 ft). When the outer wing is folded over top, it is supported by cradles to ensure it remains in place and secure while spraying in the 18.3-m (60-ft) configuration in rough fields.

• Increased boom sections provide the operator more precise application:

• 24.4-m (80-ft) boom-five sections

• 27.4-m (90-ft) boom-seven sections

• The breakaway ends of the boom offer the operator protection against damaging the boom if the boom unexpectedly hits an obstacle. The breakaway section of the boom uses a design that holds the breakaway from breaking backward while operating normally in the field, but when something is contacted, it moves rearward and out of the way to prevent major damage.

• Each breakaway section resets using a spring, and then resets back to the spray position.

• When the booms are folded in, the transport cradles on the machine support a large portion of the boom that, in turn, spreads out the stress.

• While in transport position, the booms are cradled so that visibility is maximized to either side of the sprayer. By folding the booms flat, visibility is increased and overall height of the machine is not affected.

• Turbocharged PowerTech™ PSS 4.5L (274.6-cu in.) Tier 4 diesel engine delivers 129 kW (173 hp)

• 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.

• Four-cylinder, eight-valve head (two valves per cylinder)

• Cooled exhaust gas recirculation (EGR)
