FIELD: agriculture.
SUBSTANCE: spreader comprises a body installed onto a wheeled mover with a detachable rear board and a guide plate fixed to a body bottom, a tilling and spreading device. The tilling and spreading device is arranged in the form of rotors that rotate with the help of a hydromotor. Rotors are a set of blades rigidly fixed on the shaft in a radial manner and installed diametrically oppositely, being arranged in a staggered manner relative to blades of other rotors. The device is arranged as detachable and is fixed to the body side walls. The body is installed with the possibility to vary its angle of inclination with the help of a hydraulic cylinder. The guide plate has an arched shape, is displaced relative to the tilling and spreading device towards the rear board and is fixed to the body bottom.
EFFECT: invention makes it possible to expand technological capabilities of a tractor trailer and to increase efficiency.
