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 as an extra seeder with separate hopper and metering device to ensure a rapid implementation of cover crops 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 power harrow mounted seed drill, the e-drill maxi plus. In this combination, the a-drill will allow applying an additional sort of seeds/fertilizer 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.
|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.
Two control boxes are available:
