Combination lawn mower tool

Abstract

A tool for use as a special wrench, flywheel puller, valve remover, and valve and valve seat grinder. The tool includes two rectangular bars of steel which may be bolted in one of two positions to either provide an extension handle when the tool is used as a special wrench or to provide a double thickness of steel when the tool is used as a flywheel puller. One of the bars carries a pair of angle iron sections which define therewith a C-shaped clamp, and a threaded bolt protrudes through one of the angle sections for compressing a valve spring when using the tool for removing a valve. The threaded bolt also includes a handle for turning the same which carries a rubber disc which may be removed and chucked in a speed drill to grind a valve or valve seat.
