With this free application you can get the right values for your LEMKEN fertiliser spreader quickly and easily. You can determine the correct setting of your fertiliser spreader in just four steps: 1. selection of the spreading material: mineral fertiliser, natural fertiliser, slug pellets or seeds 2. selection of the exact type of the chosen spreading material 3. selecting the fertiliser spreader model and entering the type of throwing vane, working width, forward speed and the distribution rate 4. print or export the recommended settings The determined values can be easily transferred to an ISOBUS terminal via USB stick, memory card or manual input. Forget about hours of studying spreading charts - LEMKEN Fertitest makes it easy for you! Disponible en franΓ§ais DostΔ™pny w jΔ™zyku polskim Beschikbaar in het Nederlands
