Deere launches new SP sprayers
Next generation self-propelled sprayers due to touch down in Oz in early 2020It has been a busy couple of weeks for the iconic green and yellow brand. First it announced a new four tracked tractor addition to its stable, the 8RX; then the updated 7R high horsepower tractor range and now two new self-propelled sprayer models that the company claims offer increased performance, precision and comfort.
The next generation of sprayers – the R4140i with a 4000-litre capacity and R4150i with 5000-litre capacity are manufactured at the company's Horst factory in The Netherlands.
The focus of the latest developments, Deere said, has been on improving sprayer output while ensuring that the highest possible application quality is maintained and also delivering an improved operator environment.
The premium design cab offers a new generation operator interface with fully integrated technology, such as 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.
Both models also come with upgraded lighting packages for improved visibility at night or in poor light conditions. The new cab is available at two specification levels depending on customer requirements, as well as with optional Category 4 operator protection to meet the latest safety regulations.
The R4140i is available with a choice of carbon fibre or steel booms, while the R4150i is available with carbon fibre only. Both are available with widths from 24 to 36m and feature John Deere's PowrSpray solution system with direct rate control for fast filling and highly accurate application rates, Deere said.
An automated AirRinse system helps reduce the PowrSpray system's dead volume to a low 5-litres.
Another new piece of technology on the R4140i and R4150i sprayers is the innovative ExactApply system which changes spray nozzles automatically depending on application rate and speed. Producers can also change nozzles manually from the cab if they need. ExactApply maintains droplet size while changing speed through the use of pulse width modulation (PWM) technology up to 30Hz.
With ExactApply, each nozzle is controlled individually via GPS based section control. With PWM enabled, turn compensation ensures that application rates remain consistent across the full boom width even when turning the sprayer.
Deere said the ExactApply technology enables savings in crop protection products, while at the same time increasing yield by up to three per cent by keeping under/overdosing to a minimum.
The sprayers also feature a new 50km/h transmission option.
Production of the John Deere R4140i and R4150i has started , with the first units due to arrive on Australian shores early next year.
