Pneumatic seeder integrated on cultivator or seed drill for the simultaneous application of cover crops or an extra sort of seeds/fertiliser
The Kverneland a-drill has been designed to ensure a rapid implementation of cover crop during stubble operation at minimum costs.
Moreover, Kverneland has extended the scope of application and offers the option to integrate the a-drill also onto the range of power harrow mounted seed drills, e-drill compact, e-drill maxi and e-drill maxi plus. In this combination 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, ...).
|Hopper capacity||Hopper||Weight w/o stairs & guards|
|a-drill 200||200 litres||translucent plastic hopper||110kg|
|a-drill 500||500 litres||translucent plastic hopper||153kg|
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:
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.
