Rapid A

A pneumatic seed drill with extreme capacity for optimal drilling

Rapid 25 years


Simplicity is key in the new design

Thanks to its array of front tools and drilling systems, the pneumatic seed drill Rapid is always the right choice, irrespective of cropping system. The unique depth control function and coulter pressure result in optimal seed placement even at high driving speeds. The fan on Rapid A 400-800S is integrated high up on the front edge of the seed hopper, minimising dust intake and noise. Few moving parts and cushioning on all working parts give the machine an extremely long life.

Rapid A 800S


Rapid for drilling in different tillage systems

Drilling directly in stubble, after ploughing or in a reduced tillage system are all possible. Thanks to Rapid’s powerful front tool and soil-cultivating seed discs, it can drill in any conditions. This saves many passes before drilling. The high coulter pressure gives good penetration into the soil and very good possibilities for direct drilling.
The pneumatic seed drill Rapid can drill everything from small-seeded crops such as grass leys to large-seeded crops such as beans.



Wide range of front tools

Rapid with the right front tool makes it possible to achieve the almost impossible.

Maintenance-free bearings

As of year model 2016, V30 hubs are being introduced on the machine’s 410 mm seed discs and on System Disc. The bearings have improved service life and a design that provides better protection against dust and soil, at the same time as they require no lubrication
Maintenance-free bearing 




Large tubeless tyres with big contact surface

Each wheel presses down the soil over two rows of seed and one of fertiliser. This reconsolidation ensures good contact between soil and seed, and thus good water supply to the germinating seedling.
The tubeless tyres allow the air pressure to be lowered to 1.5 bar for good work result also in wet conditions. The tyre has been designed for long life.



Rapid A 800S


OffSet increases capacity

OffSet means that alternate wheels in the carrying press wheel unit are placed 190 mm backwards on a separate axle. This creates a gap between the alternate wheels where soil and crop trash can flow through and pass out behind the seed drill. This avoids soil ridging up in front of the row of wheels in wet conditions.


Interactive Depth Control

This system provides the driver with unique opportunities to fine-tune drilling depth on the go with immediate effect, a great advantage  on variable soils. A separate position sensor indicates the position of the cylinder and displays it on the E-Control screen. After adjustment, the main cylinder is locked in the new position by double hydraulic valves. This makes Interactive Depth Control a very reliable system with no risk of accidental changes in drilling depth. 



Integrated fan and platform


Seed hopper with integrated fan - Rapid A 400-800S

The integrated fan runs at a lower speed, with reduced fuel consumption and quieter operation as a result. This enhancement has no impact at all on performance, as fan capacity is just as high as before. Its high location reduces the amount of dust and plant residue that gets in, increasing drilling accuracy. The seed hopper has also been redesigned with integrated working lights for those days when work continues as dusk falls.

Centralised platform

Rapid A 400-800S has a centralised platform with safe access from both sides, saving time for the operator.



Exact metering


Exact metering

The pneumatic metering system Fenix can handle all seed rates from 1.5 kg/ha up to 500 kg/ha without any parts having to be changed. Thanks to the hydraulic drive, high rates can be drilled without lowering the driving speed. Rapid A 600 and 800 have two seed meters, so half-machine shut-off comes as standard.

The hydraulic fan always provides the right amount of air. The rev count of the fan is monitored via E-Control in the tractor cab. On Rapid A Combi there are two fans, one for seed and one for fertiliser. The rev count is easy to adjust using the tractor hydraulics.



Rapid RDA


Extreme capacity

Rapid A has pneumatic metering and is available in working widths from 4 to 8 metres. The drilling capacity is very high, while the soil cultivating action is exceptional. Despite its impressive dimensions, the machine is easy to operate. Rapid A is also available as a combi model in 6 and 8 m width.



Rapid A 600S


Individual suspension on wing packers

The wing packers on Rapid A 400-800S are equipped with individual suspension of up to 100 kg per packer wheel. The individual suspension provides improved consolidation and seed placement on light soils. Tracking is excellent, even when operating over uneven ground.




Combi for reliable results

The pneumatic seed drill Rapid A is available with and without fertiliser. Interest in fertiliser placement is increasing globally, in pace with the higher costs of inputs and increasing environmental awareness. Väderstad can offer many years of experience within this area.

Nutrient placement during drilling gives a fast and reliable fertilisation effect. Since the fertiliser is placed in moist soil, there is less dependence on rain, while placement also gives high yield and better nutrient use efficiency.

Rapid 600C and 800C have a hopper with an adjustable dividing wall that separates seed and fertiliser. The hopper can be set in three positions: 60/40, 50/50 or seed only. A hydraulically powered auger meters out the fertiliser directly into the air stream in the distributor head. If the whole machine is used for seed, the auger is reversed so that it transports seed to the front hopper where it is metered out by the Fenix metering system. A lever allows easy conversion.




Jumbo for high seed capacity

Rapid A 600J and 800J are versions of the combi machine, but without the fertiliser function.




With Väderstad E-Services, Rapid is set for the future

With the introduction of Wi-Fi (Wireless Fidelity) and iPad Air to the Väderstad programme, the machines can be controlled with the help of wireless communication. User-friendliness, cost-effectiveness and ease of update are just some of the major advantages with the iPad Air solution compared with conventional systems. Väderstad’s control solutions have been gathered together under the family name Väderstad E-Services.

SeedEye - new seed counting technology

The operator sets the desired seed volume per square metre on an iPad without needing to climb down from the tractor to perform conventional calibration test. The radar measures seed drill speed and E-Control continuously calculates how well the "set point" for the desired  volume of seeds per square metre agrees with the actual feed value as attained via SeedEye. The feed, which is electrically powered, is constantly regulated to produce the desired seed volume. The operator gets full control of the sowing process via the iPad display at the control panel. It is easy to vary the seed volume by entering the change on the iPad.

SeedEye will be available for Rapid A 400-800S from July 2016.

Half-machine shut-off saves money

Half-machine shut-off on Rapid A 600-800C/J/S is controlled from the cab.

On irregular fields there are great opportunities for savings. Farmers who regularly use half-machine shut-off appreciate the fact that they can save up to 5% seed and fertiliser.

Save passes with BioDrill

With BioDrill on Rapid, a ley, catch crop or other small-seeded crop can be precision-drilled at the same time as the main crop. This saves passes, time and money.
The seeds are metered out by Väderstad’s own proven Fenix system.
The nozzles for the seed are positioned behind the coulter, but in front of the press wheels, and spread the seed evenly. The seed is covered by the wheels and the following harrow.

1. Cultivation

Depending on the front tools Rapid can work either directly in the stubble or on cultivated/ploughed land.
Rapid can be equipped with different front tools:

  • CrossBoard Heavy - Perfect solution for ploughed and cultivated land with low draught requirement
  • System Agrilla CrossBoard Light - The tines efficiently rip loose large amounts of material which the CrossBoard then breaks up and levelling the soil before seed coulters. System Agrilla efficiently interrupts capillary transport of water to the surface, levels the field after ploughing and moves fine material down into the seedbed
  • System Disc - Our most versatile front tool for min till farming. Intensive soil preparation with individual rubber suspension for each disc. The disc size in combination with the conical shape ensures small soil particles, ideal for a good seed bed. The discs are made of V-55-steel with a diameter of 410 mm for superior life time
  • System Disc CrossBoard Light – our most versatile and popular front tool, perfect for working in tough ploughed or min till conditions
  • System Disc Aggressive CrossBoard Light – our heaviest front tool ideal for working in reduced tillage conditions


2. 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. Rapid has up to 150 kg coulter pressure (empty hopper) which enables penetration also under the toughest conditions.

The fertiliser discs with 250 mm spacing place the fertiliser between every second seed row to a preset depth. For optimum establishment the fertiliser should be placed at 2-3 cm deeper than the seeds.

The seed disc with 125 mm spacing cuts a small slit under the cultivated soil and places the seed in moist soil. Thereafter the seed is covered by fine soil created by the serrated edges of the discs. This is one of the explanations for the good and uniform emergence.

Rapid uses a single seed disc to achieve a seed furrow as narrow as possible. In the protected area behind the disc, the coulter places the seed. The discs are made of Swedish steel, hardened up to HRC55 - Väderstad V-55. This ensures a strong and hard disc and therefore a longer lifetime.


3. Consolidation

Each wheel consolidates the soil over two rows of seed and one row of fertiliser. Consolidation ensures good contact between soil and seed, and therefore good water supply to the germinating seed.

The packer wheels are placed in an OffSet position. This means that alternate wheels in the packer roll have been displaced 190 mm backwards on a separate axle. This creates a channel between alternate wheels through which soil and harvest trash can flow and pass out behind the seed drill. This prevents soil walling up in front of the wheel row, which is an advantage on very light soils. OffSet also allows drilling under much tougher conditions and gives the drill a lower draught requirement.


4. Loosening

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

Working angle and the pressure applied to the soil can be adjusted. This facility permits fine-tuning of the amount of cultivation achieved by the harrow, while at the same time allowing varying levels of crop residue to be dealt with.The harrow is positioned to run in-between the seed rows, so there is no risk of disturbing shallow-drilled seeds.
