Low-Emission Propane-Driven Power Trowel |
摘要 |
A power trowel for treating a concrete surface includes a support frame configured to be moved on the concrete surface. A propane supply vessel is supported by the support frame and is configured to contain propane. The propane supply vessel is positioned to reduce obstructions to the operator's view of the concrete surface. An internal combustion engine is supported by the support frame and is in fluid communication with the propane supply vessel to receive propane therefrom to power the internal combustion engine. One or more rotatable shafts are driven by the internal combustion engine, and one or more trowel blades connect to the one or more rotatable shafts so as to rotate therewith.
