x40 and x50 fertiliser spreader

Manage and control your fertilisation sites

  • Performances to delight even the most demanding
  • Exceptionally regular spreading
  • over very large widths up to 50 m
  • Extraordinary site application rate
  • Very high capacity up to 4200 l
  • Simplified logistics
  • Simple stress-free adjustment

3D view = actual spreading

The result of 30 years’ collaboration with IRSTEA (Ex-CEMAGREF), our knowledge of fertilisation is unparalleled.

  • Control of large widths, taking all area parameters into account
  • Fertiliser spreading in accordance with
    • Height
    • Width
    • Depth

Accuracy of spreading pattern – not just words …

The Epsilon System patent enables multi-coverage and guarantees optimum distribution

4 “pure” layers of fertiliser per disc

  • Continuous pipeline of granules in 2 flows as the vane takes the material
  • Pattern maintained during centrifugal acceleration whatever the rate per hectare.

Digital technology that ensures full overlap

  • Optimal back-crossing between return run speading.
  • Consistent spreading for very wide widths.

“Large width” setting becomes simple!

“Continuous” width setting with adjustable chute – modification of placement point on the disc

Invest in your safety

No gears, no discs, even no vanes to handle, especially in late spreading. Working width setting is carried out away from moving parts, in complete safety!

Manage application rate/hectare – manage your margins

1. Oscillating rate regulator:

Better than an agitator, it is self-clutching in headlands and at the ends of fields!

2. Record application rate

Up to 520 kg/min

Independent right/left modulation by GPS – you’ve been waiting for it … Sulky has produced it

Resulting from our collaboration with farmers at the cutting edge of precision agriculture, independent left and right dose modulation by GPS makes greater control over fertiliser inputs possible in transition zones, where the recommended application rate changes.

SULKY is the 1st manufacture in the world to provide the solution with its ISOBUS QUARTZ 800 Terminal or the ISOBUS John Deere Green Star 2630 Terminal.

A technology which makes it possible to:

– Reduce areas of fertiliser over-and under-application of fertiliser,

– Reduce intra-plot divergences,

– Optimise yields throughout plots.

With Right/Left modulation, no more differences between actual spreading and the recommended maps!

Second new piece of equipment available, 2 R/L low level sensors make it possible to know exactly when one side of the hopper is almost empty. The driver therefore has sufficient warning to refill his hopper and not risk working empty. The low level sensors are the ideal accessories for optimising fertiliser spreading in cases of R/L adjustment by GPS or on machines fitted with the ECONOV section cut-off. This equipment is available on the ISOBUS versions of the X40+ and X50+ fertiliser spreaders.
