Abstract
This invention relates to a sprayer having a center boom and pivotal wing booms. The wing booms can be pivoted from an extended spray position to an elevated transport position by lifting and lowering each wing boom about a longitudinal lift pivot axis. In addition, each wing boom can bi-directionally breakaway relative to the center boom by virtue of a breakaway pivot arranged between the lift pivot axis and the innermost end of the wing boom. The breakaway pivot has at least one pair of nested cams that are biased into their nested condition by at least one spring. The center boom carries a pair of support cradles that direct or cam one wing boom forwardly and the other wing boom rearwardly as the wing booms are lifted into the transport position such that the wing booms form an X-shape relative to one another. The support cradles are partially flexible to allow the wing booms to release from the cradles if they strike an obstruction.
