HighlightsPrecision and high work output Economical crop establishment Seed metering rotors for all conditions
For a rapid implementation of cover crops during stubble operation, the pneumatic seeder Kverneland a-drill has been designed to be mounted on the range of short-disc harrows Qualidisc Pro / Qualidisc Farmer the stubble cultivator, Kverneland CTC and subsoiler Kverneland DTX.
The protection of the environment has become a key topic in today’s agriculture. Due to the risk of contaminated groundwater, local over-fertilisation and soil erosion, recent European regulations, rules and policies have defined new standards. One of the main measures is the systematic coverage of soils by a vegetal cover in the autumn.
Not only will the cover crops prevent soil erosion but this will also improve the soil structure, soil fertility and biodiversity.
Kverneland has extended the scope of application even further and offers the option to integrate the pneumatic seeder a-drill also onto the range of power harrow mounted seed drills, e-drill compact, e-drill maxi and e-drill maxi plus. In these combinations the a-drill will allow applying an addditional sort of seeds/fertilser all in one pass.
Two a-drill models are available depending on the seed rate/ha and the output of the machine: a-drill 200 and 500 litres.
Both models have 8 outlets which will spread the flow of seeds uniformly over the working width. In addition, they can also be used for establishing rape or a mix of different diameters seeds (leguminous plant, crucifers, ...).
One response to the Nitrate Directive
The EU nitrate directive aims to protect water resources so-called vulnerable with a rate higher than 50 mg nitrate/l. One of the measures taken into account to avoid leaching, resulting in the generalization of the soil cover in the fall by vegetation cover, which will absorb nitrogen from the soil and air, to convert it into organic nitrogen. The cover crops will then release nitrogen to the next crop (1/3), protect soil against erosion and improve its structure.
Fans adapted to seeds, working speed and width - the a-drill can be equipped with two types of fan:
- An electric fan recommended for small seeds and allowing seed rates of 4 kg/min (for a machine 50 kg/ha - 4m working width at 12 km/h)
- A hydraulic fan (installed systematically on trailed models) for flow rates up to 14 kg/min (100 kg/ha at 12 km/h for a 7m working width)
The a-drills are delivered with two types of rotor: one for small seeds (rape, mustard, cabbage, clover, etc ...), and a medium rotor for seeds (vetch, grass, sunflower, ...). The agitator placed above the rotor ensures a steady stream of seeds. A brush, located at the base of the rotor, will regulate the flow and improve the setting accuracy.
For large seeds (peas, horse beans, etc ...), it is strongly advised to choose the Flex rotor option, which is able of deforming with large seed diameter.
Two control boxes are available:
- Version 1.2 which allows you to control rotor speed, fan speed when electric driven and switch on/off rotor and fan
- Version 5.2 which allows flow speed regulation, ha and hour counter, self-diagnosis, etc ... It can be connected to a radar or 7-pin tractor speed information plug.
