A hand held granular material spreading device including a housing with holding storage chamber for a flowable dry material where the chamber is located over a horizontally rotating impeller where there is an opening from the chamber to the impeller whereby rotation of the impeller spreads the material over an area forward of the location of the device. A valve member,,is provided in the opening from the storage chamber to the impeller and an opening is defined by the valve member and is determined by a linkage arrangement which is operated by a lever device which is rotated to adjust the position of the valve member in the opening. Stops can be provided for positioning the lever member to allow the retention of the position of the valve member without continuous pressure on the lever member.
