Speed Control: the new spreading technology!


Focus on the essentials

For your fertilization needs, ECONOV

  • Free your mind by automating all high-risk operations
  • Saves on fertilizer
  • Guarantees even distribution throughout the plot
  • Removes under- and over-dosed areas
The ECONOV works in widths from 18 to 50 meters up to 4200 l

7-year warranty

Sky is now offering a 7-year anti-perforation corrosion warranty for its DX, X, and XT fertiliser distributors, manufactured from 1 September 2019.

SPEED CONTROL: the new spreading homogeneity technology

The fruit of 30 years' collaboration with IRSTEA (formerly CEMAGREF), our knowledge of the fertilizer table is unrivalled.

Control of large widths, taking into account all groundwater parameters Fertilizer distribution by height, width and depth The development of the CEMIB test bench gave us a 3D view of the actual fertilizer slick.

Distribution precision is more than just words...

Forward speed is increasingly important when working in the field, and we are developing our mounted and towed implements to absorb these major variations in speed.

SKY's work with INRAE and AgroSup Dijon has shown that the quality of fertilizer distribution in the field varies with forward speed.

Based on this observation, and following a patented concept, SKY has developed a technology for adapting the spreading pattern to the speed of travel: SPEED CONTROL!

ECONOV, the only technology that manages the actual shape of the spread pattern ... in a curve

Width adjustment by "infinitely" adjustable chute by changing the feed point on the disc Rely on your safety No sprockets, plates or even blades to handle, especially when spreading late. Work width adjustment is carried out at a safe distance from moving parts!

Controlling throughput/ha means controlling margins

Any fertilizer spread using centrifugal fertilization is curved, not straight.

SKY is the only manufacturer in the world to manage this curved shape from its ISOBUS (QUARTZ 800) and non-ISOBUS (Matrix 840 GS) terminals.

Does Sky technology save on fertilizer?

Yes, according to Emmanuel Piron, whose team carried out the study for Irstea: “Overall, there was a 9% reduction in fertilizer application in favor of Econov, i.e. 1,380 kg applied, compared with 1,515 kg in manual mode with DPAE activated. And above all, areas of under- and over-application are virtually erased in Econov mode.”

1 – Without Econov, many under- and overdoses occur; This spreading map also shows that by choosing a test plot with pronounced shapes, Sky has put itself in real operating conditions.

2 – With Econov, areas of under- and overdosing are virtually eliminated.

With ECONOV, any combination of opening and closing sections is possible.

ECONOV in ISOBUS controls 12 equal sections regardless of working width.

1 - When starting a straight field, the sections gradually open up from the outside inwards, thus respecting the true shape of the spread pattern...in CURVE!

2 - If the spreading width is reduced, for example during the last pass, the sections close automatically according to the remaining spreading width.

Right and left modulation doubles the precision of your modulation

Unique on the market, right/left modulation doubles the precision of your fertilizer application modulation.

With this feature, you can take your precision farming approach one step further. This makes it easier for you to reach your profitability targets.

From your recommendation card, your Sky fertilizer spreader automatically modulates the fertilizer dose to the right and left.

This technology lets you :

  • Reduce areas of over- and under-fertilization,
  • Reduce intra-parcel heterogeneity,
  • Optimize yields at all points in the plot.

SKY offers a new hydraulic spreading disc drive solution, independent of engine speed.

The hydraulic drive keeps the spreading discs’ speed constant, allowing the tractor’s engine speed to be kept low (1500 rpm) at all times, separate from the PTO speed. It is available on all X40+ and X50+ ranges.
  • Simplified hanging
  • Homogeneous spreading in all conditions
  • Costs under control
As a second new feature, 2 D/G hopper end sensors let you know precisely when one side of the hopper is almost empty. This gives the driver sufficient warning to refuel his hopper and avoid the risk of working empty. Hopper end sensors are the ideal accessory for optimizing spreading when using GPS right/left modulation or on machines equipped with ECONOV section cut-off. This equipment is available on X40+ and X50+ fertilizer spreaders in ISOBUS version.
