A sprayer serves as a small capacity agricultural or lawn sprayer with spot spraying capacity. It is also used for high pressure spraying, such as a high pressure washer. The sprayer has a cone bottom tank of 2 to 200 gallon capacity which supplies a high pressure pump. A high pressure regulator controls the output of the pump and provides the high pressure supply for a high pressure washing wand. The output of the regulator may also be reduced so that the washing wand can be used for spot spraying. The output of the high pressure regulator is also supplied to a valve which, when opened, supplies liquid to a variable agitator valve for returning water to a jet agitator in the tank. Liquid from the valve is also supplied to a low pressure regulator and an on-off spray valve. The low pressure regulator regulates the pressure to the spray valve which feeds a spray boom unit for spraying agricultural chemicals and the like.
