SUBSTANCE: invention relates to the field of construction, in particular to a device for removing snow from the roof of an unheated greenhouse. Device is made in the form of external guides along the longitudinal sides of the upper part of the greenhouse guides with end stops, along which the cart is reciprocally moved. On the trolley, a blade and a sail are installed with a clearance in relation to the roof surface of the greenhouse, which drives the working stroke of the trolley with a gust of wind.
