A method and apparatus for manipulating large sections of artificial turf for the removable covering of a smooth, rigid surface such as a floor, with a large section of 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 apparatus comprises powered rollers for supporting a roll of the turf, said roll being prevented from significant horizontal motion upon the rollers by thrust bearing block members, rope-like members for attachment along a truss-like spar removably attached along the leading margin of the roll, recessed winches for pulling such rope-like members across a supporting pup-up roller assembly, motor speed controls for adjusting the rate of such rolling or unrolling, and a detachable blower and air transmission duct for developing the air cushion between the turf and rigid surface.

[ I claim:] [13.] An apparatus for removably covering a rigid, relatively smooth surface with a large section of substantially impervious, heavy duty artificial turf having a leading margin, a trailing margin and at least two side margins comprising:(a) at least one powered roller adapted to support and drive a roll of such artificial turf, said roll having two opposed ends;(b) a plurality of rope-like members secured to the leading margin of the roll of the artificial turf;(c) a winch for tensioning the members to unroll the artificial turf; and(d) a pneumatic generator for developing air pressure within the margins of the section wherein the margins are in sealing contact with the surface, the pneumatic generator comprising at least one low pressure air blower connected to the underside of the turf section by at least one portable air transmission duct joined to a duct panel releasably fastened within the margins of the turf section.
