摘要： The invention concerns a rear guard (109) for a spreader (104) for spreading natural fertilisers, as e.g. manure or compost, the spreader including comminuting means (105) for cutting up and comminuting the natural fertiliser as well as spreading means (107), where the rear guard is adapted for disposition behind the comminuting means and above the spreading means. The rear guard on the spreader according to the invention includes at least one conveying surface (203) which conveys the comminuted natural fertiliser in direction against the spreading means. The rear guard is furthermore adapted to be disposed so that at least one conveying surface is inclined in relation to the plane defined by the comminuting means. This rear guard may include a rotating belt, a vibrating surface or a super-smooth surface. Furthermore, between the rear guard and comminuting means there is provided a space which is narrowed in direction against the spreading means. Hereby is achieved a continuous and even feeding of all comminuted material down onto the spreading means with consequently large spreading width, and it is also prevented that the material clogs and blocks the spreader.
