ABSTRACT:
A towed type crop sprayer for spraying a liquid agricultural chemical upon a standing crop includes a frame having a tank mounted thereon and having a horizontal transversely extending boom assembly thereon for supporting a spray device. A centrally located cylinder and piston unit and cable tensioning mechanism are operable to produce ready vertical adjustment of the boom assembly and spray device carried thereby. The tractor which tows the crop sprayer, and the crop sprayer, are provided with belly pans to smoothly engage the standing crop to minimize damage thereto. The ground engaging wheels of the tractor and the crop sprayer are provided with grain dividers which progressively part the standing crops during movement of the tractor and crop sprayer and thereby minimize damage to the standing crop during the spraying operation.
