The spreader of liquid organic fertilizers is designed for self-loading, transportation and uniform surface application of organic fertilizers into the soil. Liquid fertilizers are recognized as the most effective; nutrient mixtures are in demand in arid areas, where the soil instantly absorbs the liquid introduced into it. The devices are equipped with a volumetric container, which is made of a high-strength metal alloy to give the iron the property of resisting oxidation and corrosion. The ARLIN has a low-slung design, off-road tires and a rugged chassis for use on any terrain. Loading is done by a vacuum system through a filling hose. HILLKON AGRO provides powerful pumps (local and Italian) for rapid suction of suspension and application of fertilizer with a wide spray range. There are indicators of pressure and filling level of the barrel, a high and low pressure valve, as well as protection against overfilling the tank. The work process is controlled from the tractor cabin.
