Designed for quick coupling with the Venta 1030 pneumatic drill, Kuhn reckons that the new disc cultivator option offers significant drilling flexibility as an alternative to the power harrow combination.
Called the CD, and currently available in widths of 3.0 and 3.5m, two rows of 400mm diameter shallow working notched discs are designed to create a fine seedbed in light soil conditions.
The unit can be fitted with the company’s new Megapacker 590mm diameter roller, or other roller options. Designed to operate in combination at up to 15km/hr, or up to 4ha/hr in the 3.0m format, the CD can also be used as a stand-alone cultivator.
The discs are supported by a single vertical arm, each holding two discs per arm. Kuhn reckons that the good under frame clearance and notched disc design creates a self-driving action in plant residues, allowing the CD to operate effectively in trashy conditions.
The disc arms are fitted onto a cross-shaped profile, with polyurethane blocks. Side deflectors, fitted on a parallelogram and extending as far as the roller, leave a level finish.
Linkage between the Venta 1030 drill and the tillage tool is kept compact thanks to a specially designed (and patented) roller frame, which says Kuhn, allows for quick interchange of tillage tools, with coupling estimated to take less than 10 minutes.
