摘要： A sled which will allow the user to experience the joy of sledding when there is no snow on the ground. The sled has wheel racks which are attached to the bottom of the base of the sled, and a plurality of oval wheels are attached to the wheel rack, and the wheels extend from adjacent the front of the sled to adjacent the rear of the sled. The foremost wheels on the wheel rack are smaller that the remaining wheels to allow the sled to be used on grassy surfaces which do not have snow thereon. The smaller wheels will make it easier for the sled to roll on non-linear hills.
