The silhouette of the R4040i Sprayer shows the benefits of locating major components to optimize weight distribution and stability. The operator sits in the natural control position, between the axles and close to the machine’s centre of gravity. He has better all-round vision, is protected from unpleasant pitching when travelling over uneven ground and enjoys feeling of complete control – like riding a thoroughbred horse, but much more comfortable.
Operating the R4040i Sprayer could not be easier: all control interfaces are familiar to John Deere customers.
XtraFlex individual wheel air suspension
Individual dual strut wheel suspension with automatic pressure adjustment provides much more than operator comfort, the suspension system maximizes stability on uneven terrain and provides greater boom stability for more precise application.
BoomTrac Pro variable boom geometry
Variable boom geometry sensors provide automatic and independent (right/left) boom-height adjustment, according to the contours of the spraying environment. Ideal for working in undulating terrain at speeds up to 20 km/h.
John Deere Section Control
The GPS-based John Deere Section Control takes over full control of the boom sections, automatically switching them on and off when leaving or entering predefined areas. Reducing skips and overlaps automatically reduces input costs for chemicals.
John Deere Section Control - minimize skips and overlap automatically Overlap and crop damage due to overspray can be avoided with John Deere Section control which reduces the application costs and increases efficiency. You can easily calculate the savings per ha or year with our Section Control calculator.
