Mounted machines for three point hydraulic linkage on the tractor
The strengths of the linkage mounted Catros compact disc harrows can be exploited especially on shorter runs and wedge shaped fields.
With working widths of 3 m. 3.5 and 4 m, the rigid three point linkage models are ideal for smaller and medium sized farms.
The hydraulic folding machines in working widths of 4 m, 5 m and 6 m are ideally suited to medium to larger sized farms and contractors.
Catros T trailed machines
When tractors with less lifting power or tractors without a hydraulic lift system at all are used, the Catros T trailed models in 3 m, 3.5 m and 4 m working widths are the ideal choice. For these models, the AMAZONE wedge ring roller serves at the same time as running gear during road transport.
The Catros T trailed models in 5.5 m and 7.5 m working widths with the wedge ring tyre roller serving simultaneously as running gear for road transport, as well as for depth control, are operated on large farms but also by contractors where more than 1,000 ha maybe have to be worked within a short period of time.
Catros 2 TS trailed machines
The standard equipment of the Catros 2 TS trailed models in 4 m, 5 m and 6 m working widths includes a bogey chassis with drawbar. Catros 2 TS models travel more smoothly, because during operation, the running gear folds completely over the centre frame. In addition, the weight of the running gear increases the soil penetration of the machine. An additional "plus" of these machines is their flexibility in operation, because depending on the prevailing field conditions, this model can be equipped with a choice of cage, tandem, tooth packer, leaf spring, knife ring or wedge ring rollers.
AMAZONE coupling frame
High output 9 m and 12 m working widths are achieved when three compact disc harrows are mounted onto the AMAZONE coupling frame. When turning on the headland, and for road transport, these three lifting frames are hydraulically raised. The AMAZONE coupling frame is also suited for operation with the ED precision air seeder or a D9 seed drill. This technology has been designed for operation on single site, large estates in Eastern Europe.
Ideal: the Catros for the incorporation of liquid manures
Whether as a three point linkage mounted machine mounted on a self-propelled tanker or via a separate operational pass, Catros compact disc harrows are also superbly suited for the incorporation of liquid manure. The unique disc technology with its maintenance-free bearings and the perfectly matching rear roller ensures utmost functional reliability even under these extreme conditions.
Extremely precise, extremely shallow
Catros discs with their smooth rims are the ideal solution for the precise, extremely shallow and intensively mixing stubble work at working depths of 3 cm to 5 cm resulting in optimum conditions, for both the germination of volunteer grain and weed seeds, and quick straw breakdown.
For larger amounts of plant organic matter

Catros+ discs with their serrated rims and a larger diameter really show their strength when incorporating large amounts of straw or plant organic matter. They are, for instance, used for incorporating maize straw and stubble, the ploughing up of grassland or for the replanting of fallow land. For stubble work, in cereal fields, the Catros + discs work slightly deeper at 5 cm to 7 cm.
Perfect contour following – individually suspended discs
Whether Catros or Catros+, on every model, each disc is individually suspended in the frame via elastic rubber sprung elements. Better than machines with rigid disc suspension, every Catros concave disc can individually follow the ground contours, so that not only are the tracks filled up, but they are actually worked, ensuring an evenly shallow soil tillage operation even with prevailing undulations on the soil surface. The individual suspension of the discs – without a continuous shaft – at the same time allows the optimum passage of material through.
Aggressively angled discs
With a cutting angle of 17° at the front and 14° to the rear, the Catros discs are arranged especially aggressively ensuring the uninterrupted transfer of the soil-straw mixture from the first to the second row of discs resulting in a first class mixing of soil and plant material. Compared with shallower angled discs, the discharge angle of the more aggressive disc arrangement is noticeably smaller. So the boiling soil-straw mixture settles down again on the soil surface in front of the following roller.
The result: a superb levelling effect via the perfect smooth running of the machine.
Safe and absolutely maintenance free
The sprung rubber mountings allow for the optimum adaptation of the concave discs to the soil surface. The large diameter of the rubber buffer blocks gives a high spring pressure to prevent impact.
High quality sealing for bearings
The combined sealing of felt ring and high quality face seal ensure the 2-row angular contact bearings of the levelling discs are completely sealed. This is why one initial oil fill is sufficient for lifetime lubrication making grease nipples unnecessary
Face seals have been used for decades in military and road construction equipment where the rollers on the running gear of caterpillar-tracked vehicles have to be effectively sealed and continue to work absolutely reliably under the toughest of operational conditions.
Highly comfortable – the offset slide mechanism
Thanks to the uncomplicated and compact build is the need for adjustment kept to a minimum. So, in cases where the soil has not been loosened across the full working width, the setting of the disc rows can, via the offset slide mechanism, be quickly, simply optimised and without tools. The adjustment is carried out via the four-sided eccentric block that acts as the limit stop.
When, due to wear, the disc diameters decrease in the course of time, with the aid of the offset slide mechanism the disc position can also be adapted in such a way that the soil can still be moved across the full working area. This results in a noticeable extension of the service life.
Optimum setting of the disc row stagger
On a rigid Catros, in 3 m and 3.5 m working width, the full working width can be always made use of with the aid of the offset slide. For transport the disc rows are pushed close and locked into the transport position. Prior to operation, they are unlocked again and separated. The shifting is actuated by utilising the resistance in the soil, the physical locking and unlocking is via a rope from the tractor cab.
Unique and almost always ideal – the wedge ring roller
For reconsolidating the soil after the discing operation, various following rollers are available for all three-point linkage machines with or without a bogey chassis. Choose the right roller for your individual situation.
In most applications the AMAZONE wedge ring roller is the ideal tool. It perfectly levels the soil surface whilst the reconsolidation is only carried out in strips. These strips provide an optimum soil contact resulting in ideal germination conditions for volunteer grain and weed seeds. The open, unconsolidated areas in between are still able to let water infiltrate, so that the risk of capping is minimised – even on pressure sensitive soils.
The alternatives
The simple cage roller {1) is mainly used where smaller tractors with limited lifting power are available as the towing vehicle. This roller is comparatively cheap, achieves less reconsolidation and is less suited for operation in wetter soil conditions.
Tandem rollers {2) are often used for seedbed preparation. As the rear, smaller roller, rotates faster than the one in the front, it slightly loosens up the top soil enabling wet soil to dry better. Where wet conditions, and/or too many stones prevail, tandem rollers are not recommended.
With tooth packer rollers (3) an even, however, not so intense, soil reconsolidation is left over the entire working width. They are favoured for use in vegetable production systems.
The advantage of the knife ring rollers is their cutting effect mainly on clayey soils so that they are particularly well suited for reconsolidating dry, heavy and clayey soils.
The leaf spring rollers are superbly suited for the use on light sandy soils. Their large diameter and the open design ensure high functional reliability under these conditions.
Integrated running gear
All Catros-T compact disc harrows (working widths 3 m, 3.5 m, 4 m, 5.5 m and 7.5 m) are equipped with wedge ring rollers or wedge ring tyre rollers. The latter offer the same advantages as the wedge ring roller and serve at the same time as integrated running gear. With roller diameters of 580 mm and 800 mm they work perfectly even on light and sandy soils!
High Speed technology for optimised efficiency
When the Catros is lowered into the soil operational speeds of 10 to 20 km/h in a teamwork with the blockage free operating disc segments provide astonishingly high acreage outputs.
Under optimum conditions even higher speeds can be achieved at full area operation.
A high acreage output is not solely determined by working width and forward speed. The quick transfer of the implement from one field to the other due to the speedy, sophisticated folding technology and short turning periods at the field's edge have a strong effect on the acreage output.
The very compact and operator friendly design of the compact disc cultivator here sets standards irrespective whether the implement is mounted or trailed. Whereas the mounted can bring his strength into play in small fields with short plot lengths or in wedges, the trailed Catros impresses by the quick folding procedure and a clever headland management.
Benefit from the extremely low fuel consumption
With the Catros compact harrow, operational speeds of 10 km/h to 20 km/h are achieved problem-free, enabling outstandingly high work rates and reducing the operational time to a minimum. Important, however, for economical success, are both the fuel, and the wear and tear costs. In order to determine reliable figures for these costs AMAZONE has carried out trials in collaboration with the DLG test centre in Gross-Umstadt.
In all the tests, the Catros compact disc harrows proved to be extremely fuel efficient. So when stubble cultivating at a medium working depth of about 6 cm – depending on soil type and ground topography – an approximate fuel consumption of only 4 l/ha was measured. Similarly favourable were the consumption figures during seedbed preparation.
Minimal – the wearing costs
The concave discs of the Catros offer outstanding durability. Depending on the prevailing conditions – that means around 500 ha per metre of implement width.
At an average of only 1 €/ha the wearing costs are extremely low and, more importantly, noticeably more favourable than at, for instance, cultivator shares. Thanks to the maintenance-free bearings with their integrated face seals and the overload safety mountings even the repair costs are minimised.
