ABSTRACT:
A field sprayer is self propelled and includes a frame with an engine mounted on the frame, four wheels hydraulically driven, a tank and a boom supported by the frame and extending outwardly to the sides. The frame includes a longitudinally beam, a front transverse channel and a rear transverse channel. Each of the channels supports a pair of axle members separately pivotal about axis adjacent the center line of the frame. Each axle member includes a horizontal portion which can be extended on-the-go and a vertical portion which is attached to the wheel. A gas spring is connected between the channel and the upper surface of the axle member. Articulated steering is provided by a vertical pin connecting the front portion of the frame relative to the rear portion of the frame with the pin being arranged just rearward of the front axle. The boom is adjustable in height to accommodate both fully grown crops and ground spraying conditions. The boom includes a pair of support beams and a spray shield defined by two separate pieces projecting outwardly from the respective support beams.
