An agricultural sprayer (10) comprises a mobile frame (12) supporting a spray system (90) in which the water and chemical concentrate are stored in separate tanks (92, 94, 96 and 98) for mixture in the desired ratio as needed responsive to travel of the sprayer so as to facilitate application at the proper rate. The frame (12) preferably comprises a main frame section (14) with outboard pairs of pivotal frame sections (16, 18) which are individually supported by adjustable gauge wheels (34, 54) movable between raised and lowered positions relative to the ground by actuator assemblies (60). The spray system (90) includes a water tank (92) and a plurality of chemical tanks (94, 96 and 98) connected through individual shut-off valves, adjustable, positive displacement pumps, and an electrostatic water treater, to a plurality of spray heads.

A frame for an agricultural implement, such as a sprayer, comprising: a mobile main frame section having front and rear ends and opposite sides; a hitch secured to the front end of said main frame section; a pair of inner frame sections connected to opposite sides of said main frame section for pivotal movement about first generally-longitudinal, laterally spaced-apart axes; a pair of outer frame sections connected to the sides of said inner frame sections opposite said main frame section for pivotal movement about second generally-longitudinal, laterally spaced-apart axes; a first gauge wheel mounted on each inner frame section; a second gauge wheel mounted on each outer frame section; a movable slide mounted on each inner frame section; a rigid link pivotally connected between each slide and the associated outer frame section; and actuator means coupled between the main frame section and each slide for selectively effecting relative pivotal movement of said inner and outer frame sections between raised and lowered positions.
