Catros⁺ 03-2TS trailed compact disc harrow

The trailed compact disc harrow with bogey chassis

The folding mounted compact disc harrow Catros⁺ 03-2TS demonstrates its capability in shallow stubble cultivation. The 510 mm discs penetrate well into the soil and ensure a shallow and intensively mixed soil tillage. The X-Cutter, also available from AMAZONE, offers a special disc for very shallow soil tillage from 2 to 8 cm. The Catros can be combined with various different front tools on account of the bogey chassis.

• Catros⁺ 4003-2TS, 4.0 m working width
• Catros⁺ 5003-2TS, 5.0 m working width
• Catros⁺ 6003-2TS, 6.0 m working width
• Catros⁺ 7003-2TS, 7.0 m working width

The basic version of the Catros-2TS, having working widths from 4 to 7 m, includes the bogey chassis mounted to the rear of the machine. The weight of the chassis can be used to give better penetration on heavier soils. In addition, the TS chassis serves to provide vibration damping under extreme conditions. However, it is not required for turning at the headland. The machine can easily turn on the roller.

The new Catros generation – for higher work rates

With the Catros 03, AMAZONE offers a perfected compact disc harrow of the latest generation. The working depth is no longer set via the rear roller on the Catros⁺ 03 but is now done by rotating the complete disc element. A fixed linkage between the two rows of discs ensures that both rows always work at the same depth. Setting the disc stagger is a thing of the past.

Advantages of the Catros 03

• Smart Frame System 
• Simple setting of the working depth by rotating the complete disc module 
• Open frame design for optimum through-passage

Modular design of the compact disc harrows

• Choice of a variety of front tools 
• Smooth, fine or coarse serrated discs 
• Wide choice of different rollers 
• Possible combination with the GreenDrill seeder box

The Smart Frame System from AMAZONE is a completely new design of working depth adjustment for compact disc harrows. The complete row of discs is turned to adjust the working depth. The discs are either turned away from the frame to work deeper or up towards the frame to work shallower. In this respect, the main frame always remains parallel to the ground.

• Completely independent depth adjustment of the front tools and main working section
• The first and second row of discs always work at the same depth
• Convenient for a quick change of the working depth, e.g. in order to work deeper in tramlines or on the headland

Huge through-passage, always perfectly adapted to the working depth

• The distance between the discs and the main frame automatically increases the deeper you work. When the working depth is increased, the discs are turned away from the frame and the rear roller.

A top argument for the Catros 03 is the Smart Frame System with flexible working depth adjustment of the individual tools

• Independent adjustment of the front tool and the disc
• Independent adjustment of the front tool and the disc in relation to the frame

• The Smart Frame System offers maximum comfort in combination with the infinitely variable hydraulic working depth adjustment
• There is no need to leave the cab to change the working depth
• The scales display the current settings and are perfectly visible from the tractor seat
• In addition to the independent setting of the front tools and the discs, the rear harrow setting remains unchanged when the working depth is changed

1. Easy depth adjustment of the base machine
Models in the Catros 03 series feature a unique of working depth adjustment concept. The roller has a fixed connection with the main frame. The two rows of discs are completely rotated to adjust the working depth.

• Comfortable working depth adjustment, as the main frame remains in the same position.
• Blockage-free in extreme conditions. Turning the rows of discs leaves more space between the discs and the frame and roller.

2. Flexible working depth adjustment of the front tools
AMAZONE offers the right tool combination for all conditions with a wide selection of front tools.

• Independent adjustment of the front tool and the disc
• Independent adjustment of the front tool and the disc in relation to the frame

3. Independent depth of the roller and the rear harrow
With more than 10 different rollers and therefore probably the widest roller range on the market, AMAZONE offers the ideal roller for every soil type. The various rollers ensure optimum reconsolidation according to individual requirements. The working depth of the roller is independent of the working depth of the discs, so there is no need for time-consuming setting and adjustment of the height!

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.

The serrated, 510 mm diameter Catros⁺ discs are characterised by their more aggressive operation and a more reliable penetration even under difficult conditions. The optimum operational range of these discs is for stubble tillage, seedbed preparation and also the incorporation of catch crop residues.

• Working depths from 5 to 14 cm
• Thickness of discs 5 mm/disc diameter 510 mm/smooth, fine serrated or coarse serrated
• Universal use for more intensive incorporation
• More aggressive operation
• Incorporation of organic fertilisers

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 benefits

• Maintenance-free disc bearings with face seals and life-long lubrication
• Maintenance-free overload protection via rubber spring elements
• Individual disc suspension for optimised contour following and excellent through passage

1. 2-row angular contact ball bearing
2. 2 x seal ring (O-Ring)
3. 2 x cast rings with face seal
4. Face seal built into conical seats
5. Gear oil filled housing
6. Proven 1,000,000 times over!

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.
