发明名称 Tool for holding a rotatable lawn mower blade
摘要 A tool for holding a lawn mower blade in a mower during removal and replacement. The tool comprises a U-shaped bracket having a horizontal web and a pair of upstanding horizontally-spaced flanges. A bolt extends through bolt holes in the flanges at a level above the web. The web, flanges, and bolt encircle the lawn mower blade and define a space for retaining an end portion of the lawn mower blade. Alternate bolt hole arrangements in the flanges enable the bolt to be repositioned at different spacings and angles relative to the web, to accommodate lawn mower blades having different size air vanes with different angular dispositions. An elongated handle is attached to the underside of the web and is offset downwardly to clear the bottom edge of the skirt of a lawn mower housing.
