After drilling, seedbed preparation is the tillage operation that requires the greatest precision. NZ Aggressive is a precision tine harrow 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. The tine harrow 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.
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.
Easy to extend
NZA 700 can easily be extended to NZA 800 and NZA 900 can be extended to NZA 1000.
The tine harrow 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.
