An air driven hydraulic system for spraying liquids comprising a double acting cylinder positioned relative to a rail or track, said cylinder having a piston positioned therein, said piston having a first end and a second end, and having an oil supply to said first end of said piston and an air supply to the second end of said piston, said hydraulic system having means for alternately controlling the supply of air and oil to said cylinder to move said piston in alternating directions, said rail or track having a mobile carrier positioned thereon and being moved by means attached to said piston and said carrier, the acceleration of said carrier being controlled by bleeding off air from said means for controlling the supply of air and oil, and the speed of said carrier being controlled by the flow of oil from said piston, and means for adjusting the bleeding off of air and the flow of oil to independently control the acceleration and speed of said carrier.
