description FIELD: agricultural engineering, in particular, machines for surface application of organic fertilizers. ^ SUBSTANCE: spreader has drive part, hopper including charging hole equipped with safety grid and remote-controlled closure, mixing device made in the form of bladed shaft terminating in screw, dosing shutter, and spreading device. The latter has individual drive connected with tractor takeoff shaft. Diameter of ejector of spreading device is twice the diameter of screw and is equipped with at least six blades inclined backward at an angle of 40 deg. Ejector axis is positioned above screw axis and separated therefrom by value making 1/2 of the radius of screw. Ejector has rotational velocity exceeding by 1.5 times that of screw. Spreader of such construction allows labor intensity to be increased by 1.8 times and does not affect the surrounding medium. ^ EFFECT: uniform dosed feeding of fertilizer onto spreading device and uniform distribution of applied fertilizer over the width of spreader, simplified maintenance, and enhanced reliability in operation. ^ 3 dwg
