FIELD: agricultural engineering, in particular, straw grinding equipment.

SUBSTANCE: grinder-spreader has frame mounted on chassis and adapted for carrying of successively arranged pickup, feeder and grinding chamber with grinding working member and vertical dividers for dividing of air-and-straw flow. Discharge throat and widening baffler are arranged behind vertical air-and-straw flow dividers. Discharge throat has hopper with dosing device and rotating disks with blades. Dependence of distance between spindle of rotation of grinding working member and spindle of rotation of disks cited in Description is to be satisfied for preventing grinding chamber from clogging with ground straw. Detachable hopper with dosing device allows mineral fertilizers to be introduced into ground straw to provide for fast decomposition of straw after spreading over field.

EFFECT: increased efficiency and wider operational capabilities.
