NZ Aggressive

A heavy, intensive working seedbed cultivator with Crossboard for effective levelling

After drilling, seedbed preparation is the tillage operation that requires the greatest precision. NZ Aggressive is a precision cultivator that simplifies harrowing operations and has a guaranteed long life. Its exceptional cultivating capability saves passes and releases capacity. The OffSet-positioned bogie wheels give excellent manoeuvrability and depth control, which can easily be adjusted from the cab.

Quality that lasts

The lattice design is a high quality framework structure of square profile steel lying in-line. Each weld is carefully applied and creates a uniformly strong, flexing construction, which prevents stress failures and cracking. In addition, the pipes are angled so that they can absorb impacts and stresses in an optimal way.

 


 

 

CrossBoard clears the way

CrossBoard with double-acting stabiliser bar in specialist boron steel is standard on NZA. The bar ensures that all CrossBoard tines work at the pre-set depth and carry out maximum cultivation, without the individual tines moving forwards and backwards. The bar can easily be removed when working on lighter soils or if greater throughflow is required.  
For NZ models with six axles, the tines on the rear axle can be replaced with a rear CrossBoard for additional levelling.
With the SingleKnife tool fitted on CrossBoard, the cultivation effect is upgraded further. These tools are easy to fit, without the need for tools, using the Väderstad QuickChange System.

 

   

 


 

 

Vibrating tines for best results

The intensively vibrating Agrilla Cobra tines are made from specially hardened spring steel of dimensions 10x45 mm. They are strong and have a unique ability to maintain working depth. NZ Aggressive has 7.5 cm tine spacing, with the tines distributed across 5 or 6 axles. The clearance height and the tine distribution provide impressive through-flow, in combination with intensive seedbed cultivation.

 


 

 

Depth control for increased precision

The ControlFunction on NZA allows the working depth to be adjusted easily on the go. With the help of this device, the cultivator can be set to work slightly harder on headlands or in areas where somewhat deeper cultivation is required. This increases the scope for optimal crop establishment.
The large, clear scale gives exact information about the pre-set depth. Each mark on the scale indicates a change of approx. 1 centimetre. The ControlFunction is standard on NZA 600-1000.

 


 

 

Bogie carriage for greater stability

The bogie units are offset in order to give the frame two carrying lines. This gives the cultivator stability lengthwise and ensures that the tines in the first row tines work just as deep as those in the last row. The bogie is mounted in an angular contact ball bearings unit, which provides stable attachment while allowing the bogie to work friction-free.
Having 40% of the load on the front bogie wheels and 60% on the rear gives impressive contouring on the soil and a ‘fast’ bogie that efficiently deals with uneven ground.

 

 

 


 

 

Reduce passes

A Crosskill packer behind the cultivator reduces the number of passes and gives a better seedbed with less driving. This packer is greatly appreciated by seed and sugar beet growers. In the autumn, when the soil is often cloddy and wet, the Crosskill packer has its rightful place behind the cultivator.

 


 

Extension for NZ Aggressive

 

Easy to extend

NZA 700 can easily be extended to NZA 800 and NZA 900 can be extended to NZA 1000.

 


 

NZA crumbler roller

 

Crumbler roller

NZ Aggressive now gets a further addition to its big range of tools. 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 by means of centrally positioned cranks. We have paid particular attention to fitting bearings that have an extra long life time.  

 


 

 

NZ Aggressive 500 ST, 600 T, 600

NZA ST and T are the simpler models in the NZA-series. The ST model has single wheels on the wing sections. The working depth is adjusted with index-marked crank handles and a control unit on the centre cylinder. NZA 600T has bogie wheels on the outer sections and a hydraulic master-and-slave system controls the working depth. Otherwise, the 5 and 6 m models have the same outstanding properties as the larger NZA cultivators.

 

   

 


 

 

NZ Aggressive 700-1000

NZA 700-1000 are extraordinary seedbed cultivators designed for farmers who want to have the absolute best on the market. Their cultivation effect is phenomenal and the work is often complete after the first pass.

1. Powerful CrossBoard levelling board

The front CrossBoard levels and crushes plough furrows and shifts large amounts of soil. The CrossBoard is supplied with stabilizer bars, which connect all CrossBoard tines together so that they help each other. This makes the CrossBoard even more powerful in order to reduce clods and make the soil more even.


2. AgrillaCobra tines

The upright AgrillaCobra tines are designed to maximise the movement of soil. The strong and durable tines work the soil to produce an excellent seedbed.

The tine depth can be adjusted during operation from the cabin. 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. If goosefoot points are used weed roots could efficiently be cut off. The weight from the NZ Aggressive presses the tine straight from above. The point is positioned slightly behind the tine attachment whereby sideways vibrations are achieved, improving soil throughflow and work quality.


3. Rear CrossBoard levelling

The optional rear CrossBoard including a stabilising bar finishes the levelling work done by the NZ Aggressive and is controlled with a parallel transfer linkage from the front CrossBoard. With this option the cultivator contributes to even better depth precision and levelling. 


4. Following harrow

The 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.
