Cobra-2TX trailed shallow cultivator

Precision via support wheels and roller

1. Exact depth control via support wheels and packer roller
The depth of the Cobra is adjusted via the packer roller and the large support wheels. These are integrated in the tine element to provide better matching to the topography of the terrain. Both components are mechanically connected by a coupling rod, in order to keep the relationship between the support wheels and packer roller constant at all times.

2. Exact depth control via support wheels and transport wheels when using the double harrow
When working with a double harrow, the depth is controlled via the front support wheels and the transport wheels. A particular feature is that there are tines mounted behind the transport wheels to loosen any tracks produced by the running gear. The running gear is raised completely if the Cobra is being used with following rollers.

Working depth adjustment from the cab
The coupling rod (3) between the depth control elements provides uniform adjustment at both the front and rear of the implement. The working depth can be infinitely variably adjusted from the tractor cab, in order to enable individual reaction to the changing conditions within a field. An easy-to-read scale helps with the orientation for the driver. As an alternative, the working depth can also be mechanically adjusted. A spindle is provided on each of the support wheels for this purpose.

Levelling and roller control
Owing to the parallelogram-guided following roller, a continuous constant surface pressure is applied, even if double rollers are installed. Since the levelling unit (4) is connected directly to the roller, time-consuming working depth adjustment is not required here. The levelling unit consists of trailing tines. It is automatically protected from overload thanks to leaf springs and can be easily deactivated if there is excessive organic matter. 

Various packer rollers for reconsolidation of the soil are available from AMAZONE. The right roller for every farm!

*DUW 580 pro: 4 arms instead of 3, ideal for high working speeds and stony ground.

Standard roller bearing

All following rollers on AMAZONE cultivators are equipped with bolt-on bearing shafts. This keeps repair work to a minimum in the case of bearing damage.

HD roller bearings

The HD bearing can be selected as an option for all trailed TX implements. 

• Extreme service life thanks to a metallic face seal 
• Completely maintenance-free with life-long lubrication thanks to the gear oil filling 
• Robust and hard-wearing due to a spherical roller bearing instead of a ball bearing 
• Ideal for high forward speeds and stony conditions

For seedbed preparation for maize or sugar beet, the Cobra can also be equipped with a harrow in addition to a large number of the rollers. The following harrow creates a very fine-crumbled soil surface structure and thus the perfect germination conditions for the following crops. An additional advantage when using the harrow is the optimised straw distribution.

The double harrow and duckfoot shares are the ideal combination for mechanical weed control and shallow soil tillage. The Cobra works at a shallow working depth and cuts the weeds off across the full working width. The following double harrow pulls out the weeds without any further reconsolidation. Weeds and volunteer cereals lie exposed on the soil surface and are dried out by the sun.

Advantages of the Cobra double harrow: 

• Hydraulic adjustment of the inclination of the harrow tines from the cab 
• The harrows pull out the volunteer cereals and weeds and bring them to the surface 
• Vibration of the harrow tines separates the soil from the roots 
• The sun dries out volunteer cereals and weeds Reduction in the weed pressure without the use of herbicides
• Additional straw distribution and levelling behind the combine harvester

Result: improved field hygiene and reduction in the use of plant protection agents

Double harrow system
Changing from a packer roller to a double harrow is quick and easy, as the frames are secured via clamps to enable a quick-change system (1).
