NZ Aggressive 500-1000 is a seedbed tine harrow, available in working widths from 5 to 10 metres. It has a levelling CrossBoard followed by tines with 7.5cm spacing, distributed across 5 or 6 axles. The highly intensive cultivation saves passes whilst retaining ground moisture. You benefit from a high carrying capacity, giving a constant working depth and enabling early entry into the field.
The ControlFunction on NZ Aggressive allows the working depth to be adjusted to varying soil conditions on the move.
To enable an optimal crop establishment, NZ Aggressive can be set to work slightly harder on headlands or in areas where somewhat deeper cultivation is required.
The intensively vibrating AgrillaCobra tines are made from hardened steel. The vibrations sort the soil moving larger aggregates to the top and smaller fractions in the bottom. This creates a weatherproof surface and at the same time ensuring seed-to-soil contact. The point is positioned behind its mounting, giving a very good stone resistance and long working life. The combination of good ground clearance and tine distribution provides an impressive through-flow and intensive seedbed cultivation.
CrossBoard provides an aggressive cultivation, ensuring that clods are crushed and the soil is levelled. The working intensity is easily controlled hydraulically from the cab.
The CrossBoard is equipped with master and slave cylinders, this ensures a level working result at all times. The five axle models can be equipped with a rear CrossBoard for additional levelling.
The double-acting stabiliser bar ensures that all CrossBoard tines work together as one unit, preventing individual tines to move forward or backward.
You benefit from an extremely level working result, saving passes and providing ideal conditions for the seed drill.
With the SingleKnife fitted on the CrossBoard, the cultivation effect is further intensified. This is a benefit in heavy soils or ploughed land.
SingleKnife is easy to fit, without the need for tools, using the Väderstad QuickChange System.
The support wheels are mounted as a bogie unit with offset, thereby giving the frame two carrying axles. This provides NZ Aggressive with stability lengthwise and ensures that the tines in the first row work at the same depth as the last row.
By distributing the load with 40% on the front bogie wheels and 60% on the rear, impressive contouring and great responsivity on uneven ground is achieved.
To meet differing farming needs, Väderstad offers a wide range of points for cultivators and tine harrows. With the right choice of points you are able to optimise the working result on your fields, providing the best start possible for the next crop.
Equipped with goosefoot points, NZ Aggressive is able to provide a full cut in order to control weeds.
After it has been cut by the goosefoot, the weed residues are left on the field’s surface to dry out.
NZ Aggressive 700-1000 is equipped with suspended transport wheels as standard.
The wheel suspension protects the machines frame by eliminating heavy shocks during transport.
Additionally, this results in a calm ride at higher transport speeds.
To finish the seedbed preparation, the vibrating following harrow tines create an evaporation barrier whilst sorting larger aggregates and weeds to the surface.
The pressure and working angle can be adjusted to adapt to different field conditions. A fold-back function prevents possible damages from reverse driving.
Your farm operations will increase in size over time. With NZ Aggressive, you are always ready for the next step.
The 7 metre NZ Aggressive can be extended to an 8 metre version. In the same way a 9 metre NZ Aggressive can be extended to a 10 metre version.
NZ Aggressive can be fitted with a rear drawbar so a Rollex or Rexius roller can be attached for reconsolidation. This creates a fine tilth, perfect for small seeded crops, such as sugar beets.

The front CrossBoard Heavy levels and crushes plough furrows and shifts large amounts of soil. The CrossBoard Heavy is supplied with stabilizer bars, which connect all CrossBoard tines together so that they help each other. This makes the CrossBoard Heavy even more powerful in order to reduce clods and make the soil more even.
SingleKnife
The CrossBoard Heavy can be equipped with the knife tool SingleKnife. The SingleKnife will cut clods in the top soil in order to reduce clod sizes. Fastened with the Väderstad QuickChange System - no tools needed.
SingleKnife is available both as standard version, as well as the long-life version SingleKnife Marathon enhanced with hard metal plates.
Track eradicators
The track eradicators loosen up the wheel tracks of the tractor effectively and can be adjusted individually to the desired depth.
The AgrillaCobra tines are designed to maximise the movement of soil. The strong and durable tines work the soil to produce an excellent seedbed. The clearance under the frame and the distribution of tines over 5 or 6 axles gives a good flow of soil through the machine. The distance between tines is 7.5cm which distributes the soil so that larger clods are placed on the top and smaller particles deeper, which is favorable for early drilling.
Point options
With the wide range of points available, the working result can be adjusted to fit different farming needs. The tine is constructed as a modular system, enabling quick change of points.
Goosefoot
The goosefoot point gives a full cut out and makes NZ Aggressive a true weed killer. This is particularly useful in organic farming.
6th row of tines
A 6th row of tines increases the space between the tines, which improves throughflow and ability to handle crop residues.
Wing extensions
The 7 and 9m models can easily be extended to 8 and 10m respectively. This improves the capacity at a low cost.
The last working zone provides the possibility to add features for improved finishing.
Single following harrow
The single following harrow loosens and creates an evaporation protection layer. It also protects the surface from crusting after heavy rains. The following harrow further improves the sorting of bigger aggregates on the surface and smaller particles deeper.
Also avaible as Following harrow Marathon.
Double following harrow
The double following harrow maximises the levelling capacity. It finishes the seedbed preparation by creating an evaporation barrier and sorting larger aggregates to the surface.
Also avaible as Following harrow Marathon.
Rear CrossBoard Light
The optional rear CrossBoard including a stabilising bar finishes the levelling work done by the NZ Aggressive. The working intensity of the rear CrossBoard is controlled hydraulically from the cab. With this option the tine harrow contributes to even better depth precision and levelling.
Crumble roller
The crumbler roller leaves behind a very level surface, with the soil structure reduced to a good tilth, perfect prior to drilling of small-seed crops, such as sugar beet. The contact pressure of the crumbler roller is easily adjusted.
Connecting drawbar
A connecting drawbar with hydraulic couplings makes it possible to attach a roller behind the cultivator to add reconsolidation and further reduce the amount of passes.
