Abstract: A subfloor leveling assembly for leveling floor paneling on a subfloor includes a subfloor of a floor system in a building. A leveling compound is provided that comprises wood particles that are mixed with a fluid resin. The leveling compound is spread over the subfloor to completely cover the subfloor thereby facilitating the leveling compound to settle through gravity. In this way the leveling compound defines a level surface on the subfloor. Floor paneling is provided and the floor paneling is positionable on the leveling compound when the leveling compound is spread over the subfloor. In this way the floor paneling is leveled on the subfloor.

Abstract: A mobile cart having a retractable wheel assembly. A control rod engages the gear mechanisms coupled to the deployment rods. As the control rod engages the gear mechanisms, the gear mechanisms rotate the deployment rods between a deployed state and a retracted state. The ends of the deployment rods that are located within each wheel base push against the top portion of each wheel housing, thereby pushing each wheel housing out and away from the wheel bases so that the mobile cart may be pushed on the exposed wheels.
