A new high specification 4400-litre capacity trailed sprayer from John Deere will be making its UK show debut at Cereals 2015 in June.
The R944i model on display, together with its new M Series mid specification equivalent the M944(i), mean that John Deere now offers a wider range of specifications and configurations than ever before in a machine of this size, with a choice of manual, semi-automatic or fully automated sprayers.
The latest models offer the same basic features as the larger M & R Series sprayers up to 6200 litres, but with a smaller tank size. Both new versions have the same low profile tank design and low centre of gravity for maximum stability under all spraying conditions, while the established axle steering system provides accurate tracking on the headlands to reduce wheeling damage.
Powerful, high-capacity twin piston diaphragm sprayer pumps supply liquid at 560 litres/min for fast automatic filling and spraying. An optionally available centrifugal pump boosts filling capacity to 700 litres/min.
A wide choice of durable steel spray booms is available, from 24 to 30m (double-folding) and 24 to 40m (triple-folding). These feature a central pendulum for boom levelling, anti-yaw suspension system, vertical and horizontal boom breakaway protection and durable pivot points.
Optional intelligent solutions for more accurate and efficient spraying include the BoomTrac automatic boom height control system, pressure recirculation and AutoDilute. The SolutionCommand automatic solution management system with AutoDilute lets the operator accurately fill, agitate, spray and multi-cycle rinse the sprayer, disposing of residues at the push of a button on the tractor’s GreenStar display.
The standard GreenStar 2630 display in the tractor cab supports a full range of automatic guidance, documentation, ISOBUS implement control and performance monitoring features; this and the multi-function joystick are the only two operator controls in the cab.
The new M944(i) and R944i also offer a wider range of tyre options than ever before on trailed sprayers of this capacity, to reduce ground pressure and thus help avoid compaction and soil damage. In addition, larger diameter tyres offer less rolling resistance, reducing the power required to pull the sprayer especially in difficult ground conditions.
The full range of R900 & M900 Series sprayers replace the previous 800 Series trailed models, which will stop production later in 2015.
