CatrosXL from 4 m to 8 m
New compact disc harrow for covering large areas and the incorporation of large amounts of organic matter
AMAZONE continues to write the success story of the CatrosXL compact disc harrow and is now supplementing its portfolio by offering machines having working widths from 4 to 8 m. The CatrosXL 4003-2, 5003-2 and 6003-2 will therefore be available as a folding mounted model having working widths of 4, 5 and 6 m. These models are also available in a towed TS version equipped with a drawbar and bogey chassis and can therefore also be used by smaller tractors. In addition, the CatrosXL with TX centre running gear is available as the 7003-2TX and 8003-2TX model having working widths of 7 and 8 m.
For the CatrosXL 4003-2 to 6003-2 3-point linkage mounted models, attachment categories of 3N, 3 and 4N are available. The CatrosXL 4003-2TS to 6003-2TS trailed models are equipped with a bogey chassis and drawbar and can be pulled with a Category 3–5 lower link cross shaft, a K80 ball coupling or various drawbar eyes, depending on the tractor. These attachment options for the trailed TS variant are also available for the two CatrosXL 7003-2TX and CatrosXL 8003-2TX models. For a high degree of customer flexibility with varying tractors, the different attachment options can be quickly replaced via the connecting flange if required. When working with the various different categories of lower link attachment, the drawbar cross shaft remains on the machine since only the pins need to be changed.
Perfect working quality even in areas containing a lot of organic matter
Due to the large 610 mm discs and the greater distances between the first and second row of discs and between the second row of discs and the roller, the CatrosXL excels, above all, by its high level of passage. Whether in maize stubble or when working in catch crops: The CatrosXL models having a working width of up to 8 m, combined with a high travel speed of up to 18 km/h, which are currently being introduced are a byword for maximum surface area coverage with perfect quality results and minimal fuel consumption. In addition to the coarse-serrated 610 mm discs for dry and heavy ground, customers can also choose the fine-serrated 610 mm option. This ensures a full-surface cut and maximum crumbling effect during seedbed preparation, even in cases of extremely shallow working depths.
The discs, which are individually suspended on sprung rubber mountings, ensure perfect soil contour following. The rubber elements have a special profile, with a high release force, so that the large discs maintain their working depth even under the toughest of conditions. The specially-shaped cast disc arm on the CatrosXL has been redesigned to meet the increased demands and guides the disc at a consistent depth through the soil under all conditions.
In order to further improve the contour following at the larger working widths with the Catros 7003-2TX and Catros 8003-2TX, these machines can be optionally equipped with the ContourFrame, which is unique on the market. The two wings of the disc harrow unit are hydraulically preloaded and can therefore adjust upwards and downwards to compensate for any unevenness in the ground.
With the proven disc spacing of 25 cm within a row of discs, even a large amount of crop residues can pass through the machine without any problems. The tine spacing of 12.5 cm also ensures a complete working of the entire oil surface. The special angle of attack of the front row of discs at 17° and the rear row of discs at 14° to the direction of travel ensure safe, straight running behind the tractor, as well as an ideal mixing of harvest residues with the lowest tractive power requirement. In addition, this ensures a fast soil penetration even under the toughest of conditions. The disc bearings, with maintenance-free face seal and lifetime lubrication, are well-known across the complete Catros product range and have proven themselves a million times over. They are larger in diameter to meet the increasing demands of covering bigger areas than in the case of the 100 mm smaller diameter discs on the Catros+ models.
Adjustment of the working depth
The working depth adjustment of the disc element is carried out by rotating the disc arms around the rectangular tube carrier. A connection between the two rows of discs in the machine ensures that both rows always work at the same depth. By using this type of adjustment, the entire machine always stays parallel to the ground, whereby both rows of discs always work at the same depth, even in instances where the working depth is changed, thereby preventing the machine from being slanted as a result of a change in working depth. Furthermore, as the working depth increases, the clearance between the disc element and the roller increases, so that sufficient clearance is available in front of the roller, even at increased working depths and with the movement of more soil. This enables the earth in front of the roller to settle again.
Adjustment of the working depth is infinitely variable and can be carried out mechanically using adjustable spindles on the machine or hydraulically from the cab during operation for maximum comfort. All pivot points on the disc element are maintenance-free. The height of the side discs of the machines can be adjusted separately. This enables a level working profile even when driving track-to-track.
Running gear for transport - TS or TX
The folding CatrosXL 4003-2, 5003-2 and 6003-2 models in working widths of 4 m, 5m and 6 m can be carried on the 3-point linkage or specified in the trailed TS variant with bogey chassis and drawbar. The CatrosXL-2TS is characterised by a high degree of smoothness in work because the running gear can be completely swivelled up over the frame. In addition, the weight of the running gear ensures uniform penetration of the discs into the soil, even under the toughest of conditions. As standard,models with TS running gear have an anti-vibration function, which can be activated under certain conditions, to ensure the smooth running of CatrosXL-2TS. When manoeuvring, the machine can be driven on the roller, in order to achieve quick turn-round times and high surface area coverage.
The 7 and 8 m wide CatrosXL 7003-TX and CatrosXL 8003-2TX models have an integrated centre running gear i. Thanks to the optimum distribution of weight, the machines can be transported safely on the road. At the same time, the position of the running gear offers maximum driving comfort due to the high manoeuvrability on the headland. The running gear can be equipped with oversized 700 mm tyres, so that the ground pressure during manoeuvring is minimised and the self-driving effect of the wheels is guaranteed, even in very sandy or wet locations.
Optimum reconsolidation for all soils
11 different rollers are available for the new CatrosXL, which means that AMAZONE can offer the ideal roller both for reconsolidating the soil and for depth control of the machine, depending on the type of soil and soil conditions. For light land locations, for example, a U-profile roll or double-U profile roll is available. On medium to variable soils, the wedge ring roller or wedge ring roller with matrix tyre profile is the ideal solution. Although water is retained in the soil owing to the strip-wise reconsolidation, water can still seep into the loose strips during high rainfall, and the risk of erosion or soil capping is minimised. AMAZONE offers a solution for heavy ground and clay soils with the disc roller or double disc roller. These combine a high crumbling effect, good self-driving effect and load-bearing capacity with high insensitivity to stones. Especially for a second stubble cultivation or for seedbed preparation, trailing tine harrows are also available for many rollers.
