Foldable pneumatic Seed-drill Airspeed AS4

The folding pneumatic seed-drill Airspeed AS4 is a revolutionary machine, thanks to its Alpego patented system, which allows the transfer of the seeds from the front hopper to the small container placed at the rear on top of the power harrow, thereby guaranteeing a better drilling precision, less waste of seeds and a very good balance of the tractor. Its combination with the Alpego Rubber disc coulter bar is particularly efficient, since it makes drilling possible under any type of soil: sandy, hard or very wet and sticky.


Total volume 1550 lt

Total volume 1550 liter (1400 lt in the front + 150 lt in the rear)

Two hoppers for the best balancing of the weights (Patent)

Volumetric metering unit DOSAL

Highest use flexibility of the volumetric metering unit: suitable for small and large seeds and fertilizer (from 1.8 to 350 Kg / hectare) with a few simple adjustments.

Built in wear-resistant stainless-stell materials for maximum reliability.

Suited also for processed seeds of fertilizers.


  • Multi-function computer for the control of: fan + metering unit + hectare counter + tramlines + sowing management
  • Distribution head outside of hopper
  • Radar for detecting forward speed
  • Hydraulic distribution fan
  • Pneumatic transfer of the seeds by means of an hydraulic suction pump
  • Intermediate hopper with a total volume of 150 liters
  • Volumetric metering unit for large and small seeds
  • Conveying hose between the hoppers
  • Quick emptying of the hopper
  • Electronic motor for the volumetric metering unit
  • Electronic sowing test this allows to change sowing quantities without acting directly on the metering unit
  • Dynamic variation of the seed quantity
  • Pre-Start function: early start-up of the calibrating unit
  • Reduced transport width (2
  • 50 meters) for folding implements

  • POWER-PLUS EQUIPMENT (Adds to Power equipment):
    -Tram-Line system (4 exits)
    -Second seed level for front hopper
