John Deere 400R

Application timing can make or break yield potential, but unpredictable weather and tight windows make it difficult to execute at the right moment. John Deere application solutions help you stay prepared and ready, with integrated technology and equipment that streamline setup, reduce delays, and keep you moving - so you can apply when conditions are right and protect crop performance across every acre.

The CommandDrive™ powertrain system delivers the confidence to tackle the most challenging terrain while maximizing efficiency in self-propelled spraying. Continuously monitoring for wheel slip, CommandDrive automatically transfers power to the wheels that need it most, providing real-time traction control so you can maintain a consistent speed and spray pattern over large hills and variable field conditions. When additional power is required, the system seamlessly increases engine rpm; on flat terrain, Auto Mode intelligently matches engine speed to demand, maintaining your selected ground speed and application rate at lower rpm. The result is over 20% fuel savings, reduced DEF consumption, quieter in-cab operation, and improved traction - helping you spray more efficiently, comfortably, and confidently in any conditions.

Maximize multi‑season versatility with the New Leader® DS20 Dry Spreader, engineered to keep your application equipment working longer and more efficiently throughout the year. The DS20 delivers up to 200 cu ft (5.6 m³) or 6.6 tons of dry fertilizer - helping you cover more acres with fewer stops. The 400R can be converted from liquid application to dry spreading in as little as four hours and support variable‑rate application from 75 lb./acre (34 kg/ha) up to 3 tons per acre. With a spinner height of 72 in. (1.83 m), spread widths extend up to 105 ft (32 m), while New Leader G4 spinner technology ensures a consistent, uniform spread pattern across every pass. Available in Single Bin or MultApplier Dual‑Bin configurations and built with either the durable 304 stainless steel or 409 painted steel with a #4 belt‑over‑chain conveyor, the lineup delivers proven reliability. The G4 remains the only fully integrated option with John Deere SpreadStar™ dry rate control, while new G4 Edge and G5 spreader options expand the portfolio with Ag Leader ISO‑VT dry rate control on 400 and 600 Series machines.
