PROBLEM TO BE SOLVED: To reduce the weight to be moved, and to be loaded by a wheel when the wheel is lowered and a truck is floated, by disposing a skirt-shaped seal member for isolating a space of a bottom face of the truck from an external, on a peripheral edge of the bottom face of the truck continuously, and rising the pressure in the space of the lower part of the truck through air supply means. SOLUTION: To improve the rigidity of a plate 4 which receives the natural lawn 2 of the field, plural truss beams 3 are installed in a transverse direction of a bottom face, and the reinforcement ribs 5 are installed in a direction vertical to the truss beams 3. A shock absorbing member 6 for floor grounding, is stuck to the lower face of the truss beam 3, so that it supports the total weight of the field 1 when the field 1 is used. A horizontal plate 7 is extended to a whole lower peripheral edge of the plate 4, and a skirt-shaped seal member 8 is suspended from the all-round lower edge of the horizontal plate 7. The pressure in the space S is risen to a specific value by an air compressor, and then the field 1 is risen by the lowering of the wheel 13 by the operation of a hydraulic cylinder 16. 90% of the weight of the field 1 is supported by the air pressure, and 10% of the same is supported by the wheel 13.
