John Deere has launched its next generation of self-propelled sprayers, manufactured at the company’s Horst factory in The Netherlands.

The new R4140i 4000 litre capacity and R4150i 5000 litre capacity machines have increased performance, precision, safety and operator comfort.

A key upgrade has been the introduction of ExactApply, which John Deere has been offering in the US for two years.

The intelligent solution combines the ability to change spray models from the cab or automatically depending on application rate and speed.

It can also maintain droplet size while changing speed through pulse width modulation technology up to 30Hz.

With ExactApply, each nozzle is controlled individually via GPS-based section control.

With PWM enabled, turn compensation ensures application rates remain consistent across the full boom width even when turning the sprayer.

ExactApply technology enables savings in crop protection products, while at the same time yield can be increased up to 3 per cent by reducing under/overdosing to a minimum.

The premium design cab offers a new generation operator interface with fully integrated technology, with the John Deere universal 4640 display mounted on a new armrest.

JDLink telematics for wirelessly transferring data both to and from the sprayer is available as standard, including free activation for five years.

An upgraded lighting package improves visibility at night, both when working in the field and filling the sprayer with chemicals. The sprayers also feature a new 50km/h transmission option.

The first units are due to arrive on our shores early in 2020. Visit or your local John Deere dealer.
