The present invention provides a method and apparatus for treating lawns with both granular and liquid treatment materials, at the selection of the operator. The apparatus includes a compact, hand-operated cart having a storage compartment for accommodating a bin or bins of granular treatment materials and a tank of liquid treatment material. A rotatable spreader belt receives and meters the granular material which is spread by a rotatable spinner plate as the cart is driven. Inlet and outlet hoses received within the tank of liquid material cooperate with a pumping disc rotatably mounted on the cart to provide continuous circulation of the liquid material through the hoses. A spray nozzle coupled to the inlet hose by a valve controlled by the operator, enables the operator to selectively spray the liquid material on a surface to be treated. The spray nozzle is mounted in telescoping relationship to the cart to enable the operator to select and adjust the range which the liquid is sprayed. Hand controls for both the granular spreading and spraying operations are mounted to the cart within easy reach of the operator. Accordingly, the lawn treatment cart may be used to selectively spread only granular material, spray only liquid material, or simultaneously spread and spray both types of materials. Although the apparatus is compact, it is designed to isolate the sprayed liquid from the granular spreading components to avoiding “gumming up”of those components.

A compact, hand-controlled apparatus for applying treatment materials to the terrain for enhancing and maintaining growth thereon, said apparatus including: a chassis, wheels mounted to said chassis, and a handle mounted to said chassis for propelling said chassis, said chassis including storage means for accommodating granular treatment material, means for applying said granular material to said terrain to be treated, means defined in said chassis for accommodating a liquid treatment material, hose means having an inlet and outlet received within said means for accommodating said liquid treatment material, valve means coupled to said hose means between said inlet and outlet, discharge means coupled to said valve means for discharging said liquid treatment material from said hose means, said discharge means being mounted to said chassis proximate the outer sidewall of at least one of said wheels, said wheel being disposed between said discharge means and said means for applying said granular material to shield said means for applying said granular material from the spray of said liquid treatment material from said discharge means, said valve means being selectively movable between a first position in which only said inlet and said outlet of said hose means are in fluid communication through said valve means, and a second position in which said hose means is in fluid communication with only said discharge means through said valve means, and means for transporting said liquid treatment material from said means in said chassis for accommodating said liquid treatment material and into said inlet of said hose means whenever said chassis is propelled on said wheels, said transported liquid treatment material being returned to said means for accommodating said liquid treatment material through said outlet of said hose means whenever said chassis is propelled on said wheels and said valve means is in said first position, said transported liquid treatment material being discharged through said discharge means whenever said chassis is propelled on said wheels and said valve means is in said second position, said liquid treatment material being continuously circulated through said hose means when said valve means is in said first position and said chassis is being propelled on said wheels, said continuous circulation of said liquid treatment material providing substantially uninterrupted liquid flow and pressure of said liquid treatment material transported into said hose means when said valve means is switched between said first and second positions.
