  • Patent number: 4069540
    Abstract: A machine for removing painted stripes from artificial turf, comprising an automotive vehicle carrying an engine-driven blower, water pump, water tank, and a conditioner head that is flexibly connected to the vehicle and slides on the turf. The conditioner head includes an open-bottom housing that is spring-pressed down against the turf so that there is virtually no clearance under the bottom edges of the housing. The blower pulls a vacuum inside the water tank, and the latter is connected by hoses to the conditioner housing. A rotary brush inside the housing scrubs the turf to scour away previously-softened stripe paint. Behind the brush is a nozzle that directs a high pressure spray of water down into the turf to wash away the loosened paint particles, and this is followed by a roller that presses down against the turf and rolls water ahead of it.
