Abstract: A vehicle is controllably powered to be steerably moved over an area. Mountable on the front is a cutter assembly. Also mounted on the vehicle is a hopper. Mowed cuttings are delivered by a conduit from the cutter to the hopper. That hopper is positioned atop the vehicle and coupled to the delivery end of the conduit. Moreover, the hopper is movable with respect to the vehicle into another position wherein the hopper is disengaged from the conduit and at which latter position cuttings may be easily removed.

Abstract: An evaporative cooling system includes a housing with an outlet in one wall and a pair of inlets in opposing other walls. A pair of endless belts are individually disposed inside the respective inlets with each belt being of a material to which a liquid may cling and transparent to air flow so as to achieve evaporation. A portion of each belt extends through a reservoir and the belts are driven in movement therethrough. Blower apparatus disposed between the belts draws air through the inlets and the belts and exhausts the air through the outlet.
