CombiDisc mounted compact disc harrow

The 24 serrated discs, each with a diameter of 410 mm, provide an intensive soil tillage. Working depths of 3 cm to 8 cm are possible with the CombiDisc. Thanks to its ease of pulling, working speeds of up to 15 km/h are possible. Especially on light soil types, the CombiDisc is an efficient and good alternative to the rotary harrow.

Benefits of the CombiDisc discs

• Very shallow working at depths of 3 cm to 8 cm
• Optimum seedbed preparation

The 410 mm diameter discs of the CombiDisc are the ideal solution for the extremely shallow and intensively mixing soil tillage. Due to the small disc diameter, a high disc revolution speed is achieved ensuring a very good crumbling effect. Especially on light to medium soils, the CombiDisc, in combination with a harrow-mounted seed drill, ensures the optimum seedbed.

Steeply angled discs for optimum seedbed preparation
The double-row disc harrow unit loosens, crumbles and levels the seedbed before seed placement. The discs of the CombiDisc are aggressively angled, 14° at the front disc row and 12° at the rear disc row. This angle ensures the optimum levelling of the seedbed. In conservation tillage, additionally, the straw near the surface is further distributed and mixed. In this case the disc position ensures the perfect flow of the soil-straw mixture from the first to the second disc row and results in good mixing.

Thanks to the disc suspension in pairs via elastic rubber sprung buffer blocks on the frame, the each double set of discs is able to follow the ground contours individually. In this way, a very consistent, shallow soil tillage can be carried out even with undulations in the soil surface. The suspension of the discs at the same time allows the optimum through passage of large amounts of organic matter.

The elastic rubber sprung buffer blocks suspending the discs not only serve as an optimum matching to the ground contours but also act as an overload safety device for the individual pairs of discs. The oversized rubber buffers are maintenance-free and are characterised by a large spring deflection providing safety even where large stones prevail.

Practically orientated down to the last detail:

• Contour following of the individual disc elements and with built-in overload and stone release

The CombiDisc features disc arrying arm in the wheel track and at the sides that are individually adjustable in their height to ensure an optimum cultivation and a consistent seedbed even in the tractor tracks and at the outer edges.

The telescopic side plates ensure the perfect bout to bout matching and can, for road transport, be put into the transport position quickly, simply and without tools.

Via the stepless mechanical depth adjustment, the CombiDisc can be matched very quickly and simply to the relevant application. With the mounted compact disc harrow you only need to operate as deep as necessary – thus saving fuel.

In addition, a comfortable hydraulic working depth adjustment is available enabling the easy and precise setting from the tractor cab. The large, easily-visible scale provides orientation. Allowing operation in the field to be as shallow as necessary and yet conveniently deeper on the headland and in any wheel tracks.

For operation on compaction-sensitive soils and at a reduced working depth, the optionally available tractor wheel mark eradicators make sense. They loosen the packed wheel tracks behind the tractor tyres. The position of the wheel mark eradicators can be adjusted horizontally and vertically. Depending on soil type and implementation of the machine, the wheel mark eradicators can be equipped with different wear points. Overload protection ensures a constant trip force in all positions.

The QuickLink quick coupling system allows the easy separation of the CombiDisc with a few hand clamps so that the mounted compact disc harrow can also be used in solo operation for seedbed preparation.

The universal setting tool is the ideal solution that avoids the transportation, and the troublesome searching for, of more than one spanner. Irrespective of whether the soil tillage implement or the seed drill is being used, the universal operating tool provides convenient operation.

The GreenDrill catch crop seeder box is the ideal solution for sowing catch crops or reseeding in a single pass. The GreenDrill seed hopper has a capacity of 200 litres. The seed is distributed across the full width using baffle plates. In the metering system below the seed hopper, a seed shaft is fitted with normal or fine seed wheels depending on the seed type and desired application rate.

The advantages

• Sowing catch crops and fine seeds simultaneously with stubble cultivation or soil tillage
• Various different metering rolls are available
• Wide distribution via baffle plates
• Easily accessible via access steps
• Modern in-cab operating terminal computer in two levels of equipment
