1. A method of treating an agricultural target object, the method comprising:
providing an agricultural treatment fluid through a first pressurized fluid line from a fluid source within an agricultural treatment system to a first fluid port of a treatment head assembly of the agricultural treatment system, wherein the treatment head assembly comprises:
a treatment head extension comprising the first fluid port and a second fluid port;
one or more spraying tips; and
a fluid regulator;
wherein the treatment head extension is coupled to a linkage assembly that moves the treatment head assembly;
wherein the fluid regulator is coupled to the treatment head extension;
wherein the treatment head extension is rotatably coupled to a frame;
wherein the treatment head extension rotates about a first axis, and
wherein the frame rotates about a second axis;
preventing the progress of the agricultural treatment fluid along at least one fluid route within the treatment head assembly when the fluid regulator of the agricultural treatment system is at a first position, wherein the fluid regulator is located at the treatment head assembly;
moving at least a portion of the treatment head assembly, via the linkage assembly and/or via the frame, based on the location of an agricultural target object located outside of the agricultural treatment system, wherein the treatment head extension and the fluid regulator move together when the treatment head assembly is rotated about the first axis or about the second axis;
actuating the fluid regulator to a second position;
delivering the agricultural treatment fluid from the first fluid port to one or more spraying tips when the fluid regulator is actuated to the second position, wherein the one or more spraying tips are located at the treatment head assembly; and
spraying the agricultural treatment fluid from the one or more spraying tips onto the agricultural target object.
