A sprayer attachment is designed for mounting upon a swather tractor and includes a central frame with a tank which can be carried upon the front arms of the swather tractor. Two masts each carry a respective one of a pair of booms, each for extending outwardly to a respective side of the tractor for movement with the tractor in a spraying action. Each boom includes an inner section, an outer section and a tip portion. In the folding action the outer section and tip portion are folded about a horizontal axis so as to move to a position overlying the inner section. The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle. The tip portion is also moved to the retracted position during the folding action so that the maximum height of the outer section during folding is reduced to avoid contact with power lines and the like. The booms are inclined outwardly and rearwardly in the extended position to move the center of gravity rearwardly. The tank has two recessed sides to receive the arms of the swather tractor and a front which is inclined forwardly and downwardly to improve vision. Each boom is movable vertically along a vertical supporting mast independently for height adjustment. A hydraulic and electrical coupling allows the existing control lever of the swather tractor to control the boom movement.
