Abstract:
A new and improved blade removing tool for rotary lawn mowers to facilitate the safe and convenient removal of a bolt holding the rotary blade to the motor of a lawn mower comprising, in combination:a central support assembly having a short horizontal upper plate, a long horizontal lower plate and a horizontal intermediate plate there between, with a circular aperture formed in each of the plates in axial alignment to form a vertical guide there through, the assembly having tapering sides plates coupling the horizontal plates together to hold the support assembly in a rigid trapezoidal orientation, the support assembly and apertures forming a guide adapted to be positioned over a bolt holding a rotary lawn mower blade in position and to allow the passage of a socket wrench there through for loosening and/or tightening a bolt axially aligned beneath the aperture of the lower plate:an elongated handle having an interior end extending through one of the side plates and an exterior end adapted to be held by a user to retain the support assembly against rotation during operation and use;a pair of projections each in an inverted T-shaped configuration extending downwardly from the lower plate parallel with the handle and adapted to be positioned on opposite sides of a blade during operation and use to contact the blade when a socket wrench tends to turn a bolt and the blade with resistance being provided by the user through the handle; andan optional adapter formed of an elongated plate having an upper surface in contact with the lower surface of the lower plate with a central aperture adjacent with the aperture of the lower plate and with downwardly extending end sections adapted to contact the lawn mower blade during the loosening and/or tightening of the bolt the end sections extending away from the lower plate a greater distance that the pair of projections, the optional adapter and lower plate being provided with small apertures there through in mutual alignment and with bolts extending there trough and associated nuts to hold the supplemental plate in position.
