Technology: John Deere previews new sprayer at Cereals Event

A 5,000-litre spray tank is allied to spray width of up to 36m in John Deere’s new R4050i self-propelled sprayer, which will make its UK and Ireland show debut at Cereals 2016 in Cambridgeshire in June.

Despite the extra weight of spray liquid, weight distribution has been improved, by using a carbon fibre boom, thus removing around 900kg from the rear.

Able to spray at widths of 18m or 36m, the high-performance spray boom is considerably lighter than steel or aluminium designs.

However, the carbon fibre material used in its construction is about 5.5 times stronger than steel, and it can flex, which relieves the boom structure from stresses that could cause fractures in metal booms.

The carbon fibre boom is designed to withstand loads created at high application speeds of 20km/h to 30km/h, even with very wide booms.

The boom is five times lighter than a steel equivalent, and therefore more stable, allowing automatic boom levelling systems to control it with greater precision, enabling lower boom heights and higher speeds.

The R4050i is powered by the 6.8-litre John Deere PowerTech PSS engine, producing 235 rated horse power (boosted to 255hp with intelligent power management/IPM).

The sprayer chassis features dual-strut independent wheel suspension, and hydraulic track width adjustment as standard.

There is a choice of two-wheel, four-wheel or crab steering to suit different crop and field conditions.

The R4050i is equipped as standard with the John Deere GreenStar 3 2630 touchscreen display with full FieldDoc spray documentation and ISOBUS compatibility.

Other standard features include Solution Command electronic sprayer control for automatic filling, mixing, spraying and rinsing.

John Deere’s established BoomTrac automatic boom levelling system can be upgraded to the new variable geometry BoomTrac Pro option, for increased application accuracy and efficiency. BoomTrac Pro automatically adjusts the height of the individual boom wings independently to match the terrain.

To reduce input costs by minimising overlaps or skips, John Deere’s automatic Section Control system switches individual boom sections on and off when entering or leaving predefined areas, including headlands.

LED boom lights help to maintain high productivity at night.

Scheduled to be in full production in the Netherlands for the 2018 season, the R4050i will be available in limited numbers from early 2017.
