The HE VA COMBI-DISC 550 is a disc harrow—a primary soil-working implement that combines deep loosening and fine seedbed preparation in a single pass. Disc harrows are essential in arable farming for breaking up compacted soil, incorporating crop residue, and creating the uniform, crumbly tilth required for sowing.
This machine represents a integrated three-stage system. The front working element consists of cutting discs with a diameter of 470 mm positioned ahead of the tines, which cut and turn surface material before the main loosening action. The central deep-loosening unit comprises nine tines equipped with 200 mm wear points, capable of working to a maximum depth of 400 mm and protected by hydraulic stone safety. The rear element is a short-disc harrow fitted with toothed discs 510 mm in diameter, which further break and level the soil; these discs are protected against stone damage through rubber bearing safety.
The machine operates across a working width of 5.5 metres. A V-profile roller 700 mm in diameter follows the rear discs to consolidate and smooth the seedbed. Working depth is adjusted independently via separate hydraulic controls, and an electric depth stop provides repeatable depth setting. The machine is fitted with LED lighting for visibility and a pneumatic braking system for safe towing. Attachment is via a ball coupling K80.
The unit requires a minimum drawbar pull of 350 PS (horsepower equivalent) and has an unladen weight of approximately kg. It is equipped with warning lights and warning plates for road transport. The machine is located in Austria and was manufactured in 2021. It is offered in used condition.
