The particular form of the hopper and the slow-turning agitator (77 g/min) allow an easy flow of compost with a specific humidity up to 38%.
Model SCU/DD (PATENTED) double disc has been mainly designed for the distribution of humid fertilizers (as compost, humus, concentrated manure) but it is able to distribute also gypsum and lime besides of any other type of fertilizer, guaranteeing uniformity of distribution both in full field and localized (possibility to distribute only to the RIGHT, only to the LEFT or on both sides).
