FIELD: agriculture； machine building.SUBSTANCE: fertilizer applicator comprises a frame, a fertilizer container with a fertilizer supply pipeline, a pump with a drive, a transverse beam, to which by means of attachment units working members are attached, each of which contains a cutting disc, behind which there are a ploughshare with a knife, which is attached to the cutting disc by means of a bracket, which is connected by means of a bracket through a spring safety mechanism to the stand, and a tube for supply of fertilizers. Axles of transport wheels have the possibility of changing wheel track for different spacing width. Transverse beam is equipped with hydraulic cylinders for its lowering and hydraulic cylinders designed for its folding. Frame consists of front half-frame, which is a drawbar with towing device, on which folding transverse beam is installed with working members for subsurface introduction of liquid or loose fertilizers, or cross bar with nozzles for external spraying of liquid fertilizers, and rear half-frame installed on transport wheels with fixed on it capacity for fertilizers. Both half-frames are interconnected by a horizontal hinge. Pump station includes pump for supply of liquid fertilizers and hydraulic motor for pump drive, connected to each other by means of elastic coupling. Additionally, the fertilizer applicator comprises a canister. In the tractor cabin there is a control panel of the electronic distribution unit for dosed supply of fertilizers placed on the front semi-frame. Holder of the working tool attachment is rigidly connected to the post and located under the transverse beam.EFFECT: enabling creation of convenient, simple and reliable unit, which allows efficient and qualitative introduction of different types of fertilizers in different ways.1 cl, 3 dwgИзобретение относится к области сельскохозяйственного машиностроения.
