Väderstad Rapid A exact seed metering system

Exact seed metering

At the base of the seed hopper, the seed enters the hydraulic metering system and is distributed pneumatically to the distribution heads.

The metering system Fenix can handle seed rates from 1.5kg/ha up to 500kg/ha without any parts having to be changed. Thanks to the hydraulic drive, high seed rates can be metered without lowering the driving speed.

The integrated fan runs at low speed, resulting in low fuel consumption and quiet operation. Its high location reduces the amount of dust and crop residues that gets in, increasing drilling accuracy.

Väderstad BioDrill mounted on Rapid A clearcut image

Multiple operations in one pass

By equipping Rapid A 400-800S with the mountable small seeder BioDrill 360, a small seeded crop such as cover crops or ley, can be drilled together with the main crop.

The spreader plates distribute the seed evenly in front of the packer wheels, thereby securing a good seed-to-soil contact.

BioDrill provides an accurate seeding at the same time as saving passes on the field.

Product concept

Zone 1 - Consolidation

Before drilling, the soil is consolidated by the tractor wheels. The pivot packer on Rapid ensures that the same reconsolidation is exerted on areas between tractor wheels.

Zone 2 - Seedbed preparation

To fit different farming needs and tillage practices, Rapid comes with a wide choice of front tools.The intensity can be set hydraulically from the driving seat on the move, depending on what the conditions require.

Zone 3 - Drilling

Rapid has an amazing ability to keep the seed depth under the most difficult conditions. Each packer wheel controls the drilling depth of two coulters by a unique mechanical linkage. The coulters are rubber suspended which ensures a calm operation also at high speed. Depending on model, Rapid A 400-800S has a coulter pressure up to 255kg, thus enabling an exact seed depth also under the toughest conditions.

Zone 4 - Consolidation

Each packer wheel presses the soil down over two rows of seed and one row of fertiliser. This beds the seed in thoroughly and provides optimum conditions for germination.

Zone 5 - Finishing

The following harrow creates a loose evaporation barrier that prevents surface crusting after heavy rain.
