John Deere R4040i

Engineering Architecture of the Sprayer

The John Deere R4040i self-propelled sprayer is a precision tool engineered for minimal setup time and maximum application uniformity. At the heart of the machine lies the 6.8L PowerTech PSS engine, designed to maintain consistent output across varied terrain without dropping RPM under load.

Dosage Precision and Boom Stability

The core of the machine's efficiency is the Solution Command system. It automates filling, mixing, and rinsing, virtually eliminating the risk of human error. Practically, this drastically reduces downtime, allowing the operator to manage all application tasks via the CommandCenter display without exiting the cab.

• BoomTrac Stabilization: This system maintains the boom at a precise height parallel to the ground surface. When operating at high speeds over uneven terrain, it prevents boom bounce and dipping, ensuring uniform chemical coverage and preventing overlap burns.
• Nozzle Control: Integration of Section Control with individual nozzle control minimizes overlaps during headland turns and on irregularly shaped fields, directly reducing expenditure on expensive crop protection products by up to 5-10%.

Undercarriage and Performance

The XtraFlex chassis, featuring independent pneumatic suspension on each wheel, allows for higher field speeds while minimizing soil compaction through weight distribution. Combined with the variable ground clearance system, the R4040i serves as a versatile asset, suitable for both early-season application and late-stage treatment of tall crops, where delicate handling is essential to avoid crop damage.
