Apparatus for Spreading Granular and Liquid Materials James J. Wise John A. Doherty ABSTRACT OF THE DISCLOSURE A granular and liquid material spreading system mounted on a vehicle. Granular material is moved from a hopper to a delivery means using hydraulic pumps and motors. The hydraulic system also drives a liquid delivery system. A control system is provided to control the amount of granular material and liquid material applied to a surface. The feed rate of liquid delivery is dependent upon the feed rate of the granular material. The liquid feed rate may be changed within a predetermined range. The level of liquid may be sensed to disengage the liquid delivery system. Initiation of liquid delivery reduces the feed rate of granular material by a variably selected percentage.
