Adjustable sprayer assembly

An operator-propelled agricultural sprayer assembly of the push-pull type, comprising:

• (a) an elongate horizontal frame;
• (b) a pivoting wheel assembly vertically adjustably supporting said frame at a first end thereof, to selectively vary the height of the frame first end above a supporting surface;
• (c) a pair of laterally- and vertically-adjustable side wheel assemblies at a second end of said frame, each said side wheel assembly comprising:
• (i) a horizontal, laterally slidable arm;
• (ii) a wheel;
• (iii) vertically-adjustable support means mounting said wheel at a lower end thereof and joined at an upper end thereof to said laterally slidable arm, to selectively vary the height of the frame second end above a supporting surface;
• (d) a slot structure on said frame in which said laterally slidable arms of said side wheel assemblies are opposedly received and laterally slidably adjustable relative to one another, to selectively vary the lateral spacing between the wheels of the side wheel assemblies;
• and
• (e) a spray boom assembly vertically adjustably mounted on the frame, comprising:
• (i) laterally spaced-apart vertical bars, each of said vertical bars having a slot at an upper end and a lower end thereof;
• (ii) means for selectively and vertically adjustably securing each of said laterally spaced-apart vertical bars to said frame first end;
• (iii) a laterally extending cross bar, and laterally spaced-apart horizontal bars joined to said cross bar, said laterally spaced-apart horizontal bars being selectively and longitudinally adjustably securable in either the slots at the lower ends of the vertical bars, or the slots at the upper ends of the vertical bars;
• and
• (f) spraying means mounted on said frame.
