The material moving blade has a moldboard assembly with a lower moldboard portion and an upper moldboard portion. A hinge connects the upper moldboard portion to the lower moldboard portion for pivotal movement about a horizontal axis. An upper cutting bar with an upper bar working edge is clamped to a top edge of the upper moldboard portion. A lower cutting bar with a lower bar working edge is clamped to a bottom edge of the lower moldboard portion. An actuator pivots the upper moldboard portion about the horizontal axis in one direction to a position in which the upper cutting bar is above the lower moldboard portion and in another direction to a position in which the upper bar working edge is below the lower bar working edge and the upper moldboard material contact surface faces rearward.

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).
