HYDRAULIC POWER AND CONTROL SYSTEM FOR GRANULAR FERTILIZER SPREADERS OR THE LIKE ABSTRACT OF THE DISCLOSURE A trailer-type vehicle for transporting and dispensing solid materials over the ground includes a self-contained, hydraulic power and control system driven by one of the vehicle's ground engaging wheels which operates a first dispensing mechanism at a selectable speed pro- portional to the vehicle's rate of travel over the ground, but operates a second dispensing mechanism at a constant speed regardless of the vehicle's rate of travel. A single hydraulic motor driven by a selectively engageable drive train connected with one of the vehicle's wheels is novelly em- ployed as a hydraulic pump for delivering a force transmitting fluid through a pair of control valves to a pair of hydraulic motors respectively powering the dispensing mechanisms. One of the control valves includes provision for selectively adjusting the flow rate to the associated hydrau- lic motor thereby allowing adjustment of the volume of material being dispensed per area of ground covered by the vehicle.
