XL performance when working in catch crops

AMAZONE offers a rigid compact disc harrow in working widths of up to 4 m and mounted on the 3-point linkage in the shape of the Catros^XL 03. The machine is ideally suited for farms with a high level of harvest residues and heavy soils where deeper working depths are required in order to incorporate the organic matter.

• Catros^XL 3003, 3.0 m working width
• Catros^XL 3503. 3.5 m working width
• Catros^XL 4003, 4.0 m working width

The 610 mm serrated Catros^XL discs allow deeper cultivation whilst still offering maximum mixing. The perfect penetration even under the most arduous conditions guarantees working depths up to 16 cm so that a homogeneous mix is achieved. 

• Working depths from 5 to 16 cm 
• Thickness of disc 6 mm/Disc diameter 610 mm/Coarse serrated 
• Large spacing between the second row of discs and the roller  
• Optimal for incorporating catch crops and grain maize residues

1. Catros^XL 610 mm (coarse serrated)

The X-Cutter disc has a diameter of 480 mm for a high peripheral speed and performs optimally at working depths from 2 to 8 cm. Thanks to the special wavy profile, the discs maintain that full-surface cultivation across the entire working width, even at these very shallow working depths. The special disc profile produces an intensive movement of the full-surface area and is sure to impress with its high mixing intensity close to the surface that generates faster rotting. This provides optimum conditions for the following crop. The X-Cutter disc also scores with its low pulling power requirement.

The combination of the Catros with the X-Cutter disc and the knife roller enables a multi-dimensional cutting action to take place, thereby increasing the longitudinal and lateral shredding intensity in stubbles, straw and catch crops.

Optimum shallow chopping and mixing

Very shallow tillage plays an increasingly important role when it comes to carefully managing the water balance in the soil. Shallow tillage significantly reduces the loss through evaporation of valuable soil moisture, particularly in hot and dry summers. Much less soil is moved than with other discs, which need to operate at much greater depths to move the full soil surface.

Working speeds from 10 to 18 km/h are not a problem with the Catros and Certos compact disc harrows. This enables you to achieve incredibly high work rates and keeps the working time down to a minimum. However, the low costs for fuel, wear and tear and repair are also key factors for profitable farming.

With no need to lubricate the disc bearings, this results in a significantly reduced overall maintenance time. Face seals have been used for decades in road construction equipment where rollers on the running gear of caterpillar-tracked vehicles have to be effectively sealed and work with complete reliability under the toughest of operational conditions.

The Catros⁺ and Catros^XL discs are mounted especially aggressively with an angle of 17° for the front row of discs and 14° for the rear row of discs. This ensures a smooth transfer of the soil/organic matter mix from the first to the second row of discs and results in first-class mixing of soil and plant material. Compared with flat angled discs, the discharge angle in this aggressive disc arrangement is noticeably smaller. In this way, the moved soil/organic matter mix is redeposited on the soil surface well ahead of the rear roller.

• Utilising the slotted holes, the outer discs can be adjusted for depth to ensure a clean join up between one pass and the next.

On all models, be it a Catros⁺, Catros^XL or Certos, each individual disc is suspended from the frame on elastic sprung rubber buffer blocks. This is much better than in machines with a rigid disc suspension, as each concave disc can individually follow the ground contours, meaning that wheel tracks are not simply just filled in but worked intensively. This makes for a consistent shallow tillage, even if the soil surface is uneven. At the same time, the individual suspension of the discs enables the optimum passage of large amounts of organic matter in comparison to machines where the discs are mounted in pairs, thereby increasing the through-flow.

The elastic sprung rubber buffer blocks for suspending the discs, not only ensure optimum contour following, but also act as overload safety protection on each individual disc. The large-dimensioned sprung rubber buffer blocks are maintenance-free and feature a long spring deflection that provides you with peace of mind, even in stony ground.
