Rapid A

Rapid A

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.

A reliable partner

Rapid A is available in working widths from 4 to 8 metres in seed only version and 6 to 8 metres in combi and Jumbo seed only version.

The Rapid A is easy to set up, calibration is done with a few simple steps.
Push the remote control button to fill up the bag. Weigh the sample and enter the value in the Control-Station. The Control-Station then automatically adjusts the metering unit after setting. Enter the desired seed rate in kg/ha – ready for drilling.

Customize your own Rapid

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 a front tool designed to crush clods and create a good surface before the coulters. Ideally suited for both ploughed and min till conditions.

System Disc Aggressive with Crossboard Light (RDA 400-800S) is our most aggressive front tool, perfect for working in tough ploughed or min till conditions with high demands and a lot of residues.

Precision drilling combined with extreme work capacity

Rapid is characterised by high capacity and extraordinary precision.

The seed rate is controlled with the help of soil radar so that it remains constant regardless of driving speed. During work, the soil radar measures speed and sends information to the Control-Station, which controls the hydraulic motors of the seed metering units. This always allows an exact amount of seed to be metered out in relation to driving speed. A tried and tested solution without mechanical wear that gives precision and is generally maintenance-free

The exact Fenix pneumatic seed metering system can handle all seed sizes without the need to change cell wheel. Thanks to the hydraulic drive, high rates can be drilled without driving speed having to be reduced.

The metering system together with large hopper (3300 l for seed only version and 6000 l for combi version and Jumbo seed only version) gives Rapid A very high capacity.

Tested in very tough conditions

The Rapid has a high quality 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 decide for a Rapid. This also forces us to increase the lifetime for our wear parts on the machine. A good example is the Väderstad V-55 disc.

Features

Packer between the tractor wheels (RDAC/RDAJ)

The big packer wheels on Rapid A Combi and Jumbo version is a part of the main machine carrying a part of the machine weight. Patented links to the main frame gives active steering which reduce the turning radius on the headlands significantly.

Hydraulic fan

The hydraulic fan is superior to a PTO-driven fan as it is not depending on the tractor engine rpm. Fan speed is displayed in the Control-Station and is easily adjusted using the tractor hydraulics. There is an acoustic warning if the fan rpm is deviating.

Metering system

The seed rate is controlled with the help of soil radar so that it remains constant regardless of driving speed. During work, the soil radar measures speed and sends information to the Control-Station, which controls the hydraulic motors of the seed metering units. This always allows an exact amount of seed to be metered out in relation to driving speed. On Rapid A combi version the fertiliser is distributed with a hydraulic driven auger. This powerful system allows a distribution of up to 500 kg/ha.

Control-Station

Our user friendly Control-Station is standard on all Rapid drills. Many important functions are controlled and displayed in the Control-Station. It is easily mounted in the tractor cab.

Unique depth control – not sensitive to stones

One of the great advantages of the Rapid drill is its ingenious depth control system. Each wheel in the packer roll controls two seed coulters to a preset drilling depth, while at the same time applying careful reconsolidation. This takes place continuously, without any delay and with good contouring. The depth control system gives the seed coulters a smooth and stable passage even in stony conditions.

Tramlining

Rapid A is equipped with tramlining as standard. Hatches in the distributor head stop the air and seed flow in the tramlined rows

Half machine shut off for Rapid A, 6 and 8 metre

Electrical controlled half machine shut off is a standard feature on Rapid A 600-800.

Rubber suspension

The maintenance-free and practically indestructible rubber suspension absorbs impacts and collisions, which markedly increases the lifetime of discs and bearings and therefore of the entire drill. Thanks to the rubber suspension Rapid is a good choice also in stony conditions.

Sharp, serrated seed discs

The serrated discs (410 mm diameter) of special swedish V-55 hardened steel, work aggressively in the soil. The discs cut powerfully down into the soil and provide Rapid with its ability to drill in the most variable conditions

Large hopper with roll-top

The hopper has a modern design and a large size. The hopper of the 6 and 8 m Rapid A seed only versions has a capacity of 3300 litres. On the 4 m machine this hopper is 3000 litres.
For Rapid A Combi versions, the hopper has an adjustable wall to separate the seed from the fertiliser. The entire hopper can also be used for seed, in which case it has a total volume of impressive 6200 litres.  The Rapid A Jumbo seed only versions use the same hopper as Rapid A Combi but without the adjustable wall.

OffSet wheels for consolidation

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.

Scrapers

Each wheel on the Rapid is equiped with a scraper to reduce the risk of soil stucking on the wheels.

Disc- and pre-emergence markers

Rapid has disc markers that leave a clear mark also in min till conditions. The disc angle can be adjusted.

The pre-emergence marker is operated automatically when using the tramline function of the drill. The discs leave a clearly visible mark for following operations and can be adjusted for position and cultivation effect.

Following harrow

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.

Combi drilling (Rapid A Combi version)

Placing seed and fertiliser at the same pass between every second seed row was developed in Scandinavian conditions 40 years ago. Still this method is one of the most precise, cost efficient and environmental correct way to distribute the whole or part of the fertiliser that your crop needs for its development. The depth of the fertiliser disc is stepless adjusted, and we recommend to place the fertiliser around 2-3 cm lower than the seed.

Front tools Rapid A Seed only version

Crossboard Heavy

The Crossboard Heavy toolbar makes the Rapid drill short and responsive. The turning circle on headlands is impressively small and it is easy to reverse the machine out of corners in the field.
Crossboard Heavy consists of hardened Crossboard tines with angled wearing plates to provide aggressive cultivation. Clods are crushed and the soil is leveled. The Crossboard tines do not draw up stones and is therefore suitable for stony fields.

Crossboard Light System Agrilla

Crossboard Light System Agrilla has its rightful place on lighter soils where thorough loosening is required or on soils where the surface is hard. The tines efficiently rip loose large amounts of material for the Crossboard to break up. System Agrilla efficiently breaks capillary transport of water to the surface, levels the field after ploughing and moves fine material down into the seedbed.

Track eradicators

Rapid A 400-800S can easily be provided with Agrilla X-tra track eradicators to effectively loosen the soil in the tractor tracks. The track eradicators are individually adjusted to the desired depth.

Wheel press packer Pivot (Rapid A seed only version)

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 Packers two major tasks is to consolidate the soil in-between the tractor wheels to achieve uniform condsolidation all over the machine width and reduce radius of headland turning.

Extra wheels Packer Pivot

The Pivot Packer can be fitted with two extra wheels, increasing the carrying capacity with 50%. This option is an advantage on very light soils to prevent the Pivot packer sinking too low.

CanAGRO filling auger

The filling auger is made in stainless steel, used for filling of both seed and fertiliser. The hydraulically driven filling auger allows practical and easy filling at a comfortable working height. This simplifies filling from small bags, big bags or bulk seed, for example.
For RDA 600-800C, the dimension is 5,5m x 200mm which gives a high capacity of 50m³/h. For RDA 400-800S the dimension are 4,8m x 170mm and gives a capacity of 35m³/h.
It is operated by the hydraulic fan circuit through a 3-way valve. On the hydraulic valve there is one lever to operate hydraulic lift and one lever to operate auger feeding.

BioDrill

With BioDrill, grass seed or a catch crop can be spread with precision during drilling of the main crop. The seeds are broadcasted in front of the seed coulters. The capacity of the hopper is 360 litres. The system is monitored by the same Control-Station.

Interactive depth control

This system provides the drill operator with unique possibilities to fine-tune drilling depth on the go, with immediate action, on varying soils. With one press of a button on the control box in the cab, the drilling depth adjustment function is activated. The depth can then be adjusted with 1 mm accuracy using the hydraulic lever. After adjustment the head cylinder is locked in its new position by double hydraulic valves. This makes Interactive Depth Control a very secure system with no risk of involuntary changes in drilling depth.

Distributor head for maize

As a mounting kit for the Rapid A there are special lids that enable you to drill double rows of maize with a row distance of 75 cm. Fertiliser can be applied at the same time with combi machines at desired row distance and amount.

Hopper extension Rapid A Seed only version

Fitting a hopper extension to Rapid A Seed only increases the hopper volume by approx. 900 litres.

Digitroll Seed Master Integra

Together with Digitroll, Väderstad offers a reliable seed monitoring system that gives the driver full control of the seed and fertiliser flow in every hose of the machine. Immediately when a blockage occurs the system gives an alarm. The system is self calibrating and requires a very low maintenance.

PTO Hydraulic pump

Hydraulic PTO pump is available as option if oil flow is to low from the tractor. The PTO pump is easy to mount and you easily connect it to the tractor.

Support wheel

Support wheel for RDAS is built on the same support wheel concept as our well known construction on RDAC (standard on RDA 600-800C). Equipped with tractor pattern and scrapers to work good in all conditions. It has a step-less adjustment to ensure stable work in tough conditions. The support wheel is easy to retrofit on the machine and is suitable on all front tools in the RDAS family.

Seed coulter

The seed coulter is especially made for large seeds, such as beans ensuring that you can drill large seeds with high capacity in high speed and precision. lt also works very well for normal sized and small sized seed as wheat and rape.

Reinforced tyre

The reinforced tyre is built on the Väderstad original Rapid tyre where an aramid layer is added inside. This means that even if the tyre is reinforced, it maintains its integrity in both field conditions and in transport.
The reinforcement prevents cutting marks from becoming punctures. In conditions with flint stones for example, the punctures reduce up to 90%. The tyre is also more resistant against punctures caused by stubble and thorns.
The tyre is easily recognized with its name XPR and it is marked with a coloured line in the thread.
