Rapid

Works the soil so thoroughly that it is often possible to drill directly after ploughing or cultivation

Flexibility - Rapid is always right

Rapid is fantastic in all situations - ploughed, minimum tillage or direct drilled. 20 years of experience makes the Rapid concept outstanding.
With Väderstad Rapid you obtain a powerful, soil cultivating drill that produces quality results under all conditions. Rapid is right regardless of cropping system. It makes no difference whether you want to drill directly into stubble, after ploughing or after minimal tillage.

Thanks to the powerful front tools and the soil cultivating ability of the seed coulter discs, Rapid can drill in all conditions at high speed. You save on the number of passes needed before drilling. The high coulter pressure gives good penetration ability and very good possibilities for direct drilling.

Rapid - a reliable partner

Rapid 300-400C/S has a large seed hopper, high capacity and is easy to operate. Rapid is a reliable machine with well proven technology. The machine is available in 3 m and 4 m working width, as seed only and combi.

Depth control

Rapid is fitted with a 'memory cylinder' for setting drilling depth from the cab. Drilling depth can be altered on the go if required. A clear scale on the front of the seed hopper shows the value selected.

Customize your own Rapid

RD in field

With a wide range of front tools you are able to build your own Rapid for your conditions.

  • With only Crossboard Heavy you get a very compact machine with high flexibility that is easy to manouver. Perfect solution for the conventional farmer.
  • System Agrilla has its rightful place on lighter soils where thorough loosening is required or on soils where the surface is hard.
  • System Disc is ideal for min till farming.
  • System Disc with Crossboard is our most aggressive front tool, perfect for working in tough ploughed or min till conditions.

Mechanical metering system

Metering systemThe metering system on Rapid is simple yet ingenious, and gives precise metering of seed sizes from rape to beans, regardless of driving speed. It is easy to set and calibrate.

Large drive wheel follows the soil surface and drives the gearbox. Distribution can be set stepless. In each seed house a cell wheel provides continuous flow of seed to the seed coulters. In order to improve the precision when drilling small seeds a fine cell wheel can be used.

Tested in very tough conditions

The Rapid has a robust construction and has been tested in the toughest conditions possible in the Väderstad stone quarry. This is the reason why thousands of farmers every year invest in a Rapid. We also continuously improve the lifetime for our wear parts on the machine. A good example is the Väderstad V-55 disc.

Rapid concept

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.

Pivot Packer consists of two pairs of pivoting wheels that are pulled by the tractor lower link arms. The Pivot Packer has two major tasks:

  • To consolidate the soil in-between the tractor wheels to achieve uniform condsolidation all over the machine width.
  • Radius of headland turning is considerably reduced.

2. 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 - 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 V55-steel with a diameter of 410 mm for superior life time.
  • System Disc Crossboard Light. Crossboard Light in front of the System Disc levels off the field with good flexibility and can handle some trash.
  • System Disc Crossboard Heavy. Crossboard Heavy in front of System Disc levels off uneven fields also in difficult conditions. In some conditions this front tool works direct in ploughed land.

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. 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 V55. This ensures a strong and hard disc and therefore a longer lifetime.


4. 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.


5. 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.
