WORK VEHICLE WITH BOOM LOCK SYSTEM AND ASSOCIATED METHOD
A work vehicle (10) includes a frame (16) including generally upwardly extending laterally spaced side members (20). A boom structure (18) includes a pair of arms (24) pivotably connecting the boom structure (18) to the frame (16). A pressurized fluid system (54) is operably associated with the boom structure (18) for raising and lowering jointly each of the arms (24) along a path of travel adjacent a corresponding side member (20). A stop member (56) selectably extends outwardly from at least one of the side members (20) between a locking position (62) and a retracted position (64), the locking position (62) extending at least a portion of the stop member (56) into the path of travel of a corresponding arm of the boom structure (18) to prevent a lowering movement of the boom structure (18) beyond a predetermined height. A boom lock system (58) prevents the fluid system (54) from applying a fluid force to lower the boom structure (18) when the stop member (56) is in the locking position (62).
