A bottomless, rectangular, elongated box type housing has a center section, a first outer section, and a second outer section. The center section is attached to a first section of the first outer section and a first section of the second outer section by hinges, which permit the first outer section and the second outer section to rotate rearwardly in a horizontal plane. A pin passes through apertures in gussets on the center section and the first section, thereby securing the first outer section in a forwardly extended position. Likewise, a pin passes through apertures in gussets on the center section and the second outer section, thereby holding the second outer section in a forwardly extended position. A hinge permits a second section of the first outer section to pivot vertically relative to the first section of the first outer section. Likewise, a hinge permits a second section of the second outer section to pivot vertically relative to the first section of the second outer section. A carriage has a hitch attached to the forward portion of a frame, and a wheel assembly attached to the rear portion of the frame. The center section of the housing attaches to the frame of the carriage. A first wheel assembly is mounted near the end of the second section of the first outer section of the housing to provide support for the extended length of the housing. A second wheel assembly is mounted near the end of the second section of the second outer housing, also to provide support for the extended length of the housing. Nozzles connected by hoses extend through the housing for spraying vegetation there beneath.
