Megjegyzések:	Spinning disc centrifugai fertilizer spreader is important since 90% of the 140 millióntons/annum worldwide fertilizer production is spread using this simple and robust tool. Modelling isalsó important because of possible substitution of expensive indoor experiments. A combination of arecent analytical modelfor description of motion on a spinning disc and the hodographic ballistics isachieved. The combined model can be considered nearly exact for single particles leaving a conicaldisc with pitched straight vanes. The ballistic flight is approached with constant drag coefftcient thatis validated by the hodographic method. "In-silico" spreading experiments using experimentallycharacterized partiele clusters are sensitive to spreader and fertilizer properties. Parameters likeloading area on the disc and drag coefftcient in the air however, may need empirical corrections toreliably simulate transversal spreading patterns and the quality of spreading as afunction of workingwith. The present software tool may be put to good use in machine construction and teaching. Aspreader with two spinning discs is implemented in the calculations. Two minutes CPU times of alaptop are suffteient for calculations with clusters of250 particles.
