A portable distributor for particles, especially of grass seed and fertilizer, has a platform connected to a strap which goes over the shoulder of the individual carrying the distributor. The platform has a turn crank for rotating a set of gears connected to a shaft that rotates a circular finned spreader. The spreader is located over a slot in the platform through which the particles fall and are distributed in a circular pattern. The gears and other movable parts of the distributor are contained within a cover between the platform and spreader so that it caps the gears and a portion of a plate that adjusts the width of the slot. The cover prevents the gears to be clogged by the particles being distributed and also enhances safety by preventing the individual operating the crank and carrying the distributor from engaging the gearing with his or her hands or clothing.
