Disc harrow option
LOBED and flail discs are now available as options on Quivognes range of disc harrows.
The lobed disc comes in five- or six-lobe design. The five-lobe has a diameter of either 660mm (26in) or 710mm (28in) whereas the six-lobe is a 760mm (30in) disc.
In hard conditions the lobed disc has a working depth of 10-15cm (4-6in), using 15% less weight than conventionally shaped discs. Quivogne also claims a 15-20% lower power requirement for the design.
The flail disc has a more aggressive, cutting profile and works to a depth of 20-30cm (8-12in). The French firm claims that this design makes the harrows particularly suited to working in wet conditions. *
