Certos-2TX heavy trailed compact disc harrow

The Certos-2TX heavy trailed compact disc harrow is ideal for intensively mixing soil tillage and medium-deep soil tillage. With its 660 mm discs, the Certos-2TX penetrates the soil down to 20 cm and incorporates also large amounts of organic matter, blockage-free. Thanks to its wide application range, the Certos-2TX, in working widths of 5 m to 7 m, is the powerful all-rounder for any farm.

• Certos 5002-2TX, 5.0 m working width
• Certos 6002-2TX, 6.0 m working width
• Certos 7002-2TX, 7.0 m working width

The 660 mm diameter Certos discs are especially well suited for medium-deep and intensive soil tillage down to 20 cm. Due to the large diameter discs, the incorporation of copious amounts of maize stubble, sunflower residues, catch crops or tilling grassland is no problem. Furthermore, the Certos discs also work ideally under extreme conditions such as on hard and dry soils

• Working depths from 7 cm to 20 cm 
• Thickness of disc 6 mm/Disc diameter 660 mm/Coarse serrated 
• Good penetration even on heavy soils due to a high gross weight 
• Deeper, more intensive mode of operation when renovating pasture land

Perfect working results

The disc diameter on compact disc harrows has a significant impact on the working depth and the quality of work. The very large 660 mm diameter serrated discs of the Certos-2TX are set at a very aggressive angle of 22° in the front row and with an angle of 17° for the rear row of discs, which not only results in an excellent working profile, even on heavy soils, but also in an increased undercut. Furthermore, the soil is loosened perfectly and an even working profile is created in between passes as well.

Equipped with air braking as standard, the Certos 02-2TX can be transported quickly on the road with a permissible speed of 40 km/h. Please observe the national traffic regulations!

• “The whole job with the Certos is easily done, not least because the running gear is positioned between the disc rows and the roller which very much benefits the manoeuvrability.” (“profi“ Practice report for AMAZONE Certos 4001-2TX · 07/2017)

The integrated central running gear, equipped with 700/40-22.5, 550/45-22.5 or 400/60-22.5 tyres, ensures excellent manoeuvrability of the machine, both in the field and on the public road. The position of the running gear guarantees good weight distribution and allows the use of all AMAZONE rear rollers – this means that the most suitable roller depending on the soil conditions can be utilised. To avoid any rocking of the machine, the Certos-2TX is equipped as standard with a drawbar shock absorbance system whereby the pressure is matched according to the prevailing situation.

The Certos is equipped with an additional hydraulic top tie bar, in order to be able to compensate for the sideways pulling of the machine. The additional cylinder at the rear of the machine allows the simple and very sensitive correction of the machine. Via a double-acting spool valve, the machine can be set to optimally match up from the tractor cab. Especially for when working on slopes, the top tie bar is of huge benefit.

The Certos-2TX is equipped with hydraulic working depth adjustment as standard. This offers a high degree of comfort as it allows the working depth to be adjusted from the tractor cab, even on the move.

Advantages of the hydraulic working depth adjustment

• Soil tillage only as deep as necessary thanks to infinitely variable adjustment from the tractor cab
• Flexible and quick adaptation to the operating conditions (headland, wheel tracks, …)
• Clearly visible scale for orientation

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 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

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.
