Abstract: A wheel for a piece of lawn equipment specifically designed not to produce tracks in the lawn as the lawn equipment moves over the lawn. The wheel is made of two parallel circular discs spaced apart by a center spacer. The two discs are relatively thin and thereby have minimal contact with the grass blades when rolling over the lawn. The height of the wheel and the diameter of the axle are sufficient so that glass blades on the lawn are not bent downward and extend upward between the two discs. An optional ring structure made of rubber or similar material is attached over the perimeter edge of each disc to provide greater traction and to protect the edge from damage. Located inside the wheel axle is an optional bushing or wheel bearing.

In this state, to enhance the efficiency of a compressor, the superheat degree can be increased by decreasing the set value of the expansion device.
