The Dale Drills Cover Crop Cutting Disc Kit has been specially designed to help cut through heavy crop residue (particularly Cover Crops) ensuring good seed-soil contact and excellent establishment. As the Cutting Disc is designed for heavy residue conditions, it is used at a 10" (25cm row spacing). This is achieved by removing the front drilling tine on each assembly and bolting the Cutting Disc in its place. The rear tine on each assembly can be fitted with a duet style coulter which allows for both the air seed pipes to be attached to it. If placing Fertiliser the duet coulter allows both seed and fertiliser to be sown behind the rear tine. The Cutting Disc is best used to cut through the green cover crops. When bolted onto the drilling assembly the disc is designed to be align itself with the rear tine, effectively slicing a path through the residue for the rear tine to run down, creating a tilth and placing the seed. The Cutting Disc has the added benefit of reducing the amount of surface disturbance that the rear tine creates. This is due largely to the fact that the surface of the soil has been sliced by the disc reducing the amount of boiling created as the tine passes through.
