ABSTRACT:
A method of removably covering a smooth, rigid surface such as a floor, with a large section of heavy duty, artificial turf which involves pulling it across the surface while supported on a pneumatic cushion to minimize frictional drag and then relieving the cushion after the section is in place to allow it to settle onto the surface. The installation in use comprises such turf supported within its periphery on the pneumatic cushion in contactless overlying relationship above the rigid surface. The apparatus comprises powered rollers for supporting a roll of the turf, rope-like members for attachment to the roll along its leading margin, winches for pulling such rope-like members and a blower for developing the air cushion between the turf and rigid surface.
