Full control with Väderstad SeedEye
Väderstad SeedEye is a unique system for seed counting and seed monitoring. With SeedEye farmers can easily set the number of seeds per square foot, without the need for calibration. SeedEye ensures excellent seeding results with full control.

Depth setting from the cab
To be able to instantly adapt to varying soil types or differing conditions in the field, Rapid A 400-800S can be equipped with the unique depth control system Interactive Depth Control (IDC). The system enables fine-tuning of the seeding depth with 1mm accuracy on the move.
Combined with the possibility to alter the seed rate, the driver is constantly in full control of the seeding operation.
By optimizing output, the crop get the best start possible, leading to perfect emergence.

Full access
Rapid A 400–800S has a centralized platform with access from both sides, saving time for the operator. Both the hopper and the fan can be accessed when required from the platform.
To minimize downtime in the field, all discs are equipped with maintenance-free bearings.

Easy-to-use tramlining
The dynamic tramlining function makes tramlining simpler and more reliable than ever before. The function is easy to setup with the iPad-based control system Väderstad E-Control. When seeding the field, the seed drill automatically shuts off specific rows when needed to match the tire tracks of the sprayer.

Modern control system
The iPad-based control system Väderstad E-Control wirelessly delivers an extensive control and monitoring of the seeding process, while driving on the field. Additionally, you benefit from user-friendly remote set up and calibration
With the iPad you can upload the most recent program software which allows you to benefit from future developments.

Multiple operations in one pass
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 496 lbs, 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 fertilizer. 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.
