Abstract: A portable agricultural sprayer comprises a narrow elongated wheeled frame having the wheels closely spaced to permit operation between rows of plants. The frame is provided with a handle for hand-moving. The frame supports an electrically operated compressor as a source of compressed air and an electric storage battery for providing power for operation of the compressor. A storage tank is supported on the frame for containing a solution of agricultural chemicals or fertilizer or the like and is connected at one end to the output side of the compressor to be provided with compressed air for pumping the liquid to be sprayed. The other end of the storage tank is connected to valved connections to the outlet end of a pair of swivelled booms which carry adjustable nozzles for spraying agricultural chemical solutions. The booms are supported for angular movement and are provided with a suitable locking device to support the booms in a horizontal position or in a vertical position or any intermediate position.
