Devices and methods are disclosed which relate to the transportation of loads. A strong and flexible platform has a plurality of ball casters attached to its underside to carry a load by dragging the platform along the ground. The plurality of ball casters on the bottom allow it roll while the flexible platform allows it to match the contour of the ground surface. The platform is outfitted with a removable rigid frame, handles, and grommets. A wagon attachment can be attached on top of the platform to transport loose loads such as leaves and other yard waste, and a rigid tub can be inserted into the wagon attachment for denser loads such as soil and sand. The platform can be pulled by hand, animal or vehicle.
