Air cushioned spraying apparatus for spraying vegetation with chemicals while being supported above the ground by an air cushion effect has a unit with at least three air cushion cells. Each cell has a substantially cylindrical rigid body with a closed upper end and an open lower end, and a flexible skirt secured to and extending around the periphery of the open lower end of the rigidbody. Each cell also has a spray nozzle projecting downwardly into the body fromthe closed upper end and an air inlet in the body adjacent the upper end thereof. The cells are connected together so that the path of travel of each cell laterally overlaps the path of travel of another cell. Air under pressure is supplied to the cell inlets to cause air to pass therethrough and downwardly in the cell body to disperse the chemicals from the nozzle onto vegetation within the lower open end of the cell and to cause air to pass from the cell between the flexible skirt and the ground to create an air cushion effect.
