ABSTRACT:
A vehicle mounted spray boom assembly includes a breakaway spray boom and shock absorbing means for absorbing the shock on the boom assembly when a boom returns to normal position after striking an obstacle. The shock absorbing means includes a swing cylinder for rigging in and rigging out the spray boom and a tilt cylinder for tilting the boom when the boom has been rigged out. Upon occurrence of shock after an obstacle is struck, a portion of the hydraulic fluid in the swing cylinder is forced into the tilt cylinder to lift the spray boom to dissipate the shock. In addition, another cylinder may be provided for absorbing shock imparted to the boom due to vertical movement of the boom. Also the swing cylinder and tilt cylinder are hydraulically connected in parallel so that when rig out has been completed, pressurized hydraulic fluid continues to be ported to the tilt cylinder to elevate the end of the boom.
