Abstract
A sprayer boom assembly (14) includes a center boom (72), left inner and outer wing booms (100 and 106), and right inner and outer wing booms (110 and 116). A left wing hydraulic cylinder (120) pivots the left inner and outer wing booms (100 and 106) between a horizontal working position and a folded transport position. A right wing hydraulic cylinder (134) pivots the right inner and outer wing booms (110 and 116) between a horizontal working position and a folded transport position. The center boom (72) is pivotally attached to an intermediate frame (30) by a left leveling link (60) and a right leveling link (64). A left sprayer boom lock assembly (150) limits pivotal movement of the left and right leveling links (60 and 64) in a first direction when the left wing hydraulic cylinder (120) pivots the left inner wing (100) from a horizontal working position. A right sprayer boom lock assembly (152) limits pivotal movement of the left and right leveling links (60 and 64) in a second direction when the right wing hydraulic cylinder (134) pivots the right inner wing (110) from a horizontal working position. Valves (210, 212 and 214) control the supply of liquid chemicals to the nozzles (16).
