A riding lawn care vehicle may include a frame, an engine, a steering assembly, a support platform and a front platform. At least a pair of drive wheels may be operably coupled to the frame. The engine is operably coupled to the frame via an engine platform. The engine is disposed between the drive wheels to selectively provide drive power to the drive wheels via respective hydraulic pumps. The steering assembly includes control levers operably coupled to respective drive wheels via the respective hydraulic pumps. The steering assembly enables steering of the lawn care vehicle based on drive speed control of the drive wheels responsive to positioning of the control levers. The support platform is operably coupled to the frame at a rear portion of the lawn care vehicle. The front platform is operably coupled to the frame forward of the engine platform. The front platform supports the hydraulic pumps.

Modular Structures preferably usable to form human habitations in outer space are fabricated by molding. A mold comprising progressively surrounding flexible walls defines progressively surrounding cavities. A selected cavity or cavities are inflated or pressurized, as with gas, to distend to assume a predetermined configuration. Another selected cavity or cavities are injected with mold material, which is then allowed to harden. A pressurized cavity or cavities may be evacuated and then filled with mold material. In this manner, a strong structure is progressively formed is subsequent injection and hardening steps. In alternative embodiments of the molding method, supports or reinforcing members are placed within cavities prior to inflation and material injection. These supports space apart adjacent flexible mold walls and force the flexible walls to assume a desired configuration under inflated conditions. The supports can be rigid and solid; rigid, telescoping, and biased to expand; and flexible and resilient. The supports can thus resist tensile and compressive forces imposed on the flexible walls by inflation. In further alternative embodiments, magnets are placed within the mold, employing attraction and repulsion to maintain desired alignment of molded parts and to urge selected portions toward and away from others. A system of cylindrical and spherical hollow objects can be formed and connected. Connection can be solid or rotatable. The habitations can be rotated independently of one another even though connected, when an appropriate connection is provided.

The present invention pertains to the construction of modular structures used as a building blocks to create an habitation or integrated structures which form habitations. In both cases flexible molds are injected with mold materials to form the final structure created. An outer cavity of the mold is first inflated to create either a finalized shape of the structure or a partial shape for the structure. If internal constraints of the innermost cavity are already included, a finalized structural shape is obtained. If internal constraints for the innermost cavity have to be added, the final shaped is obtain after those constraints are placed within the innermost cavity.
