Fill faster and spray more accurately with the unique hydraulically driven dual-circuit PowrSpray system. It allows you to fill your sprayer in just in 10 minutes* and gives you 98 percent* rate control accuracy.
*NOTE: Measured without priming; dependent on tank size. The 98 percent accuracy figure is derived from MyJohnDeere™ Field Analyzer Beta work totals application quality.
The dual-circuit layout maximizes efficiency and ease of use. Each circuit is completely independent, features a dedicated centrifugal pump, and is optimized for specific functions. Cross contamination between the two circuits is not possible, helping to reduce rinsing requirements and residual liquid disposal.
Filling circuit consists of the self-priming centrifugal filling pump (1) which fills the solution tank and provides clean water to the eductor.
The filling circuit is separated from the spray circuit and not used during spraying, therefore is not contaminated with chemicals and does not need to be rinsed.
Spraying pressure and application rate are controlled by adjusting the speed of the centrifugal spray pump via the load sense hydraulic pump drive. This load sense hydraulic drive enables a fast and accurate rate control.
Active Pause enables the operator to incorporate crop protection chemicals and rinse chemical containers with clean water and pauses filling from the solution tank. Once the eductor is switched off, the filling pump revs up again to maximum fill capacity.
The spraying circuit is equipped with a centrifugal spray pump that provides liquid to the spray boom and agitation. Only the spray circuit gets in contact with the chemicals and therefore is the only part of the machine that needs to be rinsed.
Solution Command makes filling, spraying, and rinsing automated. The electrically controlled solution system takes away the guesswork in valve settings by automatically positioning the valves without operator mistakes.
The design of the operator’s station makes operation easy and convenient. Icons on micro keypad makes selection easy and helps to limit the risk of mistakes when filling, spraying, or rinsing.
The PowrFill™ chemical eductor hopper, spray gun, and clothing lockers stored behind the shielding with filters and hose connections are easily accessible for operation. The chemical safety card holder is located near the platform, making information about the load readily available.
Benefits of the operator’s station design include:
To match different applications five different spray systems are available. All spray systems have one thing in common: pressure recirculation. The pressurized liquid flows up to the nozzles even when not spraying. This ensures that the right concentration and the correct pressure is quickly reached and prevents underdosing or weed triangles at spray start. Even when weather conditions suddenly change, the full circulation functionality enables the operator to rinse out spray lines without spraying.
Available spray systems:
Benefits of pressure recirculation functionality includes:
TerrainCommand Pro automatically maintains a constant spray height above the crop per wing on uneven ground and in changing crop conditions, resulting in an effective deposition of spray liquid and less dissipated chemicals, better crop penetration, and reduced spray drift.
TerrainCommand Pro is offered with three sensors (one sensor per wing and one sensor next to the center frame) or five sensors (two sensors per wing and one sensor for the center frame). The five-sensor system is only available for 27-m (88.6-ft) booms or wider.
Ultrasonic sensors mounted at each end of the boom measure the height of the boom wings above the target. If the slope of the field changes and the spray boom is no longer at the desired distance to the ground or crop surface, TerrainCommand Pro controls the boom variable geometry, tilt, and height automatically.
Benefits of TerrainCommand Pro include:
TerrainCommand Pro in combination with AutoTrac™ automatic guidance system and Section Control offers better machine utilization. It enables spraying at night when spraying conditions are often much better (less wind and drift).
TerrainCommand Pro uses a dedicated proportional hydraulic valve to control the variable geometry on each boom wing. Proportional hydraulics offer both faster and smoother operation, with response modulated to the amount of boom movement necessary. The proportional hydraulic valve is also equipped with a temperature sensor that measures oil temperature. This feature provides compensation for the flow difference of the oil in different temperatures, enabling accurate variable geometry adjustments.
The round-shaped polyethylene tank is fully cradled by the frame and gives the machine a low center of gravity. This comes together with standard double-linked ProRoad axle suspension, providing stability on the road or in the field.
With its low center of gravity and even weight distribution, the R900i Series is built for stability. The entire mainframe is designed especially for the job. The heart of the mainframe is the cross structure in the center section to redirect forces, providing the strength for a long lifetime. The frame design cradles the large polyethylene tank perfectly. The special tank shape offers deep sump while the steeply sloping bottom limits chemical residue. Due to the special tank design, additional tank baffles are not needed. It is easier to agitate liquid due to the smooth tank that has less risk of spray solution sticking to the inside of the tank.
The heavy-duty axle is fully integrated and comes standard with ProRoad double-linked axle suspension.
The frame, tank, and single axle design offers better maneuverability. Regardless of the boom position, the level weight distribution helps to always keep the machine steady.
Benefits of tank, frame, and axle design include:
