Manipulating large sections of artificial turf

A method of removably covering a floor with a large section of substantially impervious, heavy duty artificial turf which comprises:

• (a) dragging the leading margin from a roll of said artificial turf across an initial portion of a floor via the application of a pulling force at plural locations along said leading margin, wherein said roll is supported on at least one powered support roller;
• (b) turning said roll of said artificial turf comprising the remainder of said section in place in an unwinding direction, while continuing the application of said pulling force to further advance the section across the floor, wherein said turning occurs via frictional contact between the periphery of said roll and said at least one powered support roller;
• (c) generating pneumatic pressure between the floor and the overlying section of artificial turf to lift the overlying section within its margins off the floor and minimize friction between the floor and the artificial turf, wherein the margins of the artificial turf section over the floor are in sealing contact with the floor;
• (d) continuing the application of pulling force until the floor is covered with the section;
• and then
• (e) relieving the pneumatic pressure to permit the section where lifted to settle onto the floor.
